• SQL Server 2008 R2 mirroring failing

  - by andriusn

  I have two Windows 2008 R2 (Amazon EC2) instances running SQL Server 2008 R2. I use 9TB striped disks (9x1TB EBS volumes) for storage. One server is running as principal and second one as mirror. Both started from the same image, database and tlog files located on striped disk. Mirror server failed 3 times in last 2 months with errors: EventID 823 The operating system returned error 2(The system cannot find the file specified.) to SQL Server during a write at offset 0x00000048058a00 in file 'D:\TLogs***_log.ldf'. Additional messages in the SQL Server error log and system event log may provide more detail. This is a severe system-level error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online. and EventID 1454 Database mirroring will be suspended. Server instance 'xxxxxxxxxx' encountered error 823, state 6, severity 24 when it was acting as a mirroring partner for database '***'. The database mirroring partners might try to recover automatically from the error and resume the mirroring session. For more information, view the error log for additional error messages. followed by EventID 19019 The MSSQLSERVER service terminated unexpectedly. After this rebooting instance is necessary to restore mirroring. First two times I thought it was hardware related (striped disk failure) and relaunched instance on new hardware. But the issue is back after few weeks again. It only affects mirror instances. Any help would be really appreciated. Thanks.

• Linux: prevent VNC from swapping like mad

  - by Weezy

  I'm accessing a MacMini (with MacOS X 10.4) from my Linux machine using VNC and there's an issue that is driving me crazy... My Linux machine has 4 GB of ram and I run a lot of various apps on it and I've got no issue at all. It's all snappy and don't hear the hard disk swapping/read/writing too often. Now with VNC, the hard disk is swapping like mad... When I'm moving things on the OS X desktop. So I was thinking of creating a ramdisk and forcing the temp VNC files to go into that ramdisk but the problem is I can't find any temp files. I've attempted to do that: #!/bin/bash while [ true ] do lsof | grep vnc done And eyeball parse the output to try to find some temp file: no luck. The VNC version I'm using is this one: $ vncviewer -version VNC Viewer Free Edition 4.1.1 for X - built Jan 30 2009 19:33:16 Copyright (C) 2002-2005 RealVNC Ltd. No matter how much data is coming from the Mac, there should be plenty of memory (4 GB of ram) so there's really no reason to swap like crazy. This is driving me mad. Any help as to how I could solve this problem is most welcome because this is literally driving me nuts.

• Upgrading Visio 2000 to Visio 2007

  - by dirtside

  I have Microsoft Visio 2000 SR 1, and recently purchased Microsoft Office Visio Standard 2007 with the understanding (supported by the product info and some other research) that I'd be able to upgrade. However, when I install 2007, it tells me it can't find a previous install of Visio, but... it's right there! Here's the exact message: "Setup can't find a version of Microsoft Office on your computer. If Office is installed on a disk or network share, click the browse button to select the appropriate disk or share... (etc.)" No matter which directory or drive I pick (various Office installs, the old Visio install, various subdirectories) it gives the following message: "The path you have chosen does not point at a qualifying upgradeable product. Click 'Retry' to try again or 'Cancel' to quit setup." Any ideas? This is a legit copy of Visio 2007 (purchased from Amazon) and the copy of Visio 2000 is legit as well. I'm not sure what exactly the installer is looking for that it would consider a "qualifying upgradeable product". A specific file?

• Setup.exe called from a batch file crashes with error 0x0000006

  - by Alex

  We're going to be installing some new software on pretty much all of our computers and I'm trying to setup a GPO to do it. We're running a Windows Server 2008 R2 domain controller and all of our machines are Windows 7. The GPO calls the following script which sits on a network share on our file server. The script it self calls an executable that sits on another network share on another server. The executable will imediatelly crash with an error 0x0000006. The event log just says this: Windows cannot access the file for one of the following reasons: there is a problem with the network connection, the disk that the file is stored on, or the storage drivers installed on this computer; or the disk is missing. Windows closed the program Setup.exe because of this error. Here's the script (which is stored on \\WIN2K8R2-F-01\Remote Applications): @ECHO OFF IF DEFINED ProgramFiles(x86) ( ECHO DEBUG: 64-bit platform SET _path="C:\Program Files (x86)\Canam" ) ELSE ( ECHO DEBUG: 32-bit platform SET _path="C:\Program Files\Canam" ) IF NOT EXIST %_path% ( ECHO DEBUG: Folder does not exist PUSHD \\WIN2K8R2-PSA-01\PSA Data\Client START "" "Setup.exe" "/q" POPD ) ELSE ( ECHO DEBUG: Folder exists ) Running the script manually as administrator also results in the same error. Setting up a shortcut with the same target and parameters works perfectly. Manually calling the executable also works. Not sure if it matters, but the installer is based on dotNETInstaller. I don't know what version though. I'd appreciate any suggestions on fixing this. Thanks in advance! UPDATE I highly doubt this matters, but the network share that the script is hosted in is a shared drive, while the network share the script references for the executable is a shared folder. Also, both shares have Domain Computers listed with full access for the sharing and security tabs. And PUSHD works without wrapping the path in quotes.

• PC only boots from Linux-based media and won't boot from DOS-based media

  - by xolstice

  I have this problem where the PC only seems to boot from a floppy disk or CD if it was created as a Linux-based bootable media. If it was created as a DOS-based bootable media the system just freezes at the starting point of the boot process. I originally asked this under question 139515 for CD booting only, and based on the given answers, I was under the impression the problem was with the CD-ROM drive; however, I have since installed a newly purchased CD-ROM drive and the same freezing occurs. This then made me try the DOS bootable floppy disk approach and I was quite surprised that it exhibited the same freezing problem. I then tried try a Linux bootable floppy and everything booted from it without any issues. As I mentioned in my original question, the PC was booting just fine from the DOS-based bootable CD, and then it suddenly decides to pull this freezing stunt. I can't remember if I changed anything in the BIOS settings that may I have caused the problem, but I am wondering if that could be the case - it is currently using the Award Module BIOS v4.60PGMA. Can anyone help?

• Windows 7 Not Starting and System Repair Not Loading

  - by Mark

  I have a Dell Inspiron 1545 running Windows 7 When turning on my PC I keep receiving a black screen with the option to use System Repair or Start Normally. Both options lead me to the System Repair background except no matter how long I wait the system restore options never show up. Choosing F8 and running all of the options including safe mode encounters the same result above. I tried to to use 2 system recovery disks 32x and 64x I downloaded and both lead to similiar results. When I choose System Repair running from the disk the System Repair Question asking to select a language pops ups but after this no matter how long I wait no other options appear. Next after restarting and selecting F8 (after hitting f12 and running from CD) I choose 'Run From Safe Mode with Command Prompt' I am able to run all of the options from System Restore with differing results: Startup Repair: Choosing this ends up in system repair indefinitely (left running 12 hrs) System Restore: Does Nothing. PC thinks for a second and then stops. When selecting ShutDown I see an error message stating there are no restore points. System Image Recovery: Service Cannot be started in Safe Mode Windows Memory Diagnostic: Runs test but then leads to system repair background which never loads system repair Command Prompt: chkdsk /r -Cannot Lock Current Drive...write protected. chkdsk /f -Cannot Lock Current Drive...write protected. bootcfg - Cannot open Boot.Ini file bootcfg - Ran all 3 (rebuildBcd, FixMbr and Fixboot) but PC still goes to System Repair background with no repair options popping up upon restart (without recovery CD). I'm on the verge of purchasing a boot utility disk for $50 unless there is anything else short of "take it to a computer shop" that somebody can suggest I try.

• Eclipse: Slow startup time

  - by ct2k7

  Hello, I've got Eclipse 3.6.1 on my MacBook Air (2010), and I'm getting slowish startup times. Well, slow, compared to my Desktop, which is somewhat less powerful and a few years old). The startup generally takes 15 seconds, and of this, 4 is spent just on the Eclipse splash screen, before Eclipse loads anything. No projects are open at startup. Here's a copy of my eclipse.ini. -startup ../../../plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar --launcher.library ../../../plugins/org.eclipse.equinox.launcher.cocoa.macosx.x86_64_1.1.1.R36x_v20100810 -showsplash org.eclipse.platform --launcher.XXMaxPermSize 512m --launcher.defaultAction openFile -vmargs -Xms256m -Xmx512m -Xdock:icon=../Resources/Eclipse.icns -XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts -Dosgi.requiredJavaVersion=1.6 -Xverify:none -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled -XX:+UnlockExperimentalVMOptions -XX:+AggressiveOpts -XX:+StringCache -XX:+UseFastAccessorMethods -XX:+UseLargePages -XX:LargePageSizeInBytes=4m -XX:AllocatePrefetchLines=1 -XX:AllocatePrefetchStyle=1 -Dide.gc=true The problem doesn't seem to be related to plugins - I've disabled the ones which I don't need, and regardless of this configuration or whether all of them are selected on startup, it only takes 1second to load the plugins. I'm running Eclipse 3.6.1 Cocoa x64 build (vanilla) with the Zend Studio plugin. The machine has 4GB RAM, an SSD with over 64% free space, 1.6GHz (4MB L2 Cache). OS is Mac OS X 10.6.6, latest Java available, 1.6. For comparison, my Desktop, an old P4 3GHZ (512K L2 Cache) with a 7200RPM drive, under 40% free space, Eclipse (same config) loads in under 7 seconds, consistently. Note, this one is a Windows machine, with latest Java installed.

• A tiered approach to cloning linux partitons

  - by Djurdjura

  I'm looking at a strategy for cloning Linux (root) partitions without having to use a Live CD. Literature suggests rightly that the source and target partitions must be umounted to be able to get a clean clone. This assumes that you need to use a LiveCD. I was wondering if instead of requiring a LiveCD, if using a 3rd partition that would emulate the LiveCD functionality, if we can't achieve the same functionality. In other words, at a high level a system with 3 partitions (all bootable): Rescue Partition (LiveCD emulation) Running Partition (Source) Backup Partition (Destination) All 3 partitions are LVMS. When it's time to clone the source partition to the backup (destination) partition, we would boot to the rescue partition, unmount the other 2 partitions (is it required?), run disk check on the source, copy to the destination (dd or simple copy to avoid replicating the defragmentation from the source), run disk check on the destination partition, update Grub menu list to force boot from either partition, and reboot into that partition. My question, is it an approach that you'd recommend? MBR in all this? Any gotchas or extra checks required? Thanks, D. PS. On recommendation from members, posting here instead of stackoverflow.com.

• Script errors when run by launchd at startup, but not when run in Terminal

  - by Mechcozmo

  Hello. I'm attempting to create a RAM disk that loads the previous contents when the system starts up, and every six hours writes the contents to a disk image. Currently, when you run the script from the terminal ("sudo bash LogToRAM.sh") everything works fine. But when run from launchd during startup, it doesn't work. Here's the lines from the log; the first line just gives some idea as to where in the boot process we are: SecurityAgent[202] Showing Login Window com.mechcozmo.LogToRAM[51] + /Developer/usr/bin/SetFile -a V /Volumes/LogfileRAMdisk com.mechcozmo.LogToRAM[51] ERROR: File Not Found. (-43) on file: /Volumes/LogfileRAMdisk com.mechcozmo.LogToRAM[51] + /usr/sbin/asr -source '/Library/Application Support/LogToRAM/RAMdisk_store.dmg' -target /Volumes/LogfileRAMdisk/ -noverify Here is the script and plist file in question. Note that 'set -vx' is up at the top of the script; it give a lot of information about what is happening in the script. My current theory is that the /Volumes directory does not exist at this stage of the boot process, but that seems unlikely to be honest.

• SQL Server 2005 standard filegroups / files for performance on SAN

  - by Blootac

  Ok so I've just been on a SQL Server course and we discussed the usage scenarios of multiple filegroups and files when in use over local RAID and local disks but we didn't touch SAN scenarios so my question is as follows; I currently have a 250 gig database running on SQL Server 2005 where some tables have a huge number of writes and others are fairly static. The database and all objects reside in a single file group with a single data file. The log file is also on the same volume. My interpretation is that separate data files should be used across different disks to lessen disk contention and that file groups should be used for partitioning of data. However, with a SAN you obviously don't really have the same issue of disk contention that you do with a small RAID setup (or at least we don't at the moment), and standard edition doesn't support partitioning. So in order to improve parallelism what should I do? My understanding of various Microsoft publications is that if I increase the number of data files, separate threads can act across each file separately. Which leads me to the question how many files should I have. One per core? Should I be putting tables and indexes with high levels of activity in separate file groups, each with the same number of data files as we have cores? Thank you

• SSD cache to minimize HDD spin-up time?

  - by sirprize

  short version first: I'm looking for Linux compatible software which is able to transparently cache HDD writes using an SSD. However, I only want to spin up the HDD once or twice a day (to write the cached data to the HDD). The rest of the time, the HDD should not be spinning due to noise concerns. Now the longer version: I have built a completely silent computer running Xubuntu. It has a A10-6700T APU, huge fanless cooler, fanless PSU, SSD. The problem is: it also has (and needs) a noisy HDD and I want to forbid spinning it up during the night. All writes should be cached on the SSD, reads are not needed in the night. Throughout every day, this computer will automatically download about 5 GB of data which will be retained for about a year, giving a total needed disk capacity of slightly less than 2 TB. This data is currently stored on a 3 TB noisy hard disk drive which is spinning day and night. Sometimes, I'll need to access some data from several months ago. However, most times I'll only need data from the last 14 days, which would fit on the SSD. Ideally, I'd like a transparent solution (all data on one filesystem) which caches all writes to the SSD, writing to the HDD only once a day. Reads would be served by the cache if they were still on the SDD, else the HDD would have to spin up. I have tried bcache without much success (using cache_mode=writeback, writeback_running=0, writeback_delay=86400, sequential_cutoff=0, congested_write_threshold_us=0 - anything missing?) and I read about ZFS ZIL/L2ARC but I'm not sure I can achieve my goal with ZFS. Any pointers? If all else fails, I will simply use some scripts to automatically copy files over to the big drive while deleting the oldest files from the SSD.

• repair partition table

  - by m.sr

  Hallo. I've just overwritten my partition table of my system's hard disk. i made a cfdisk on the wrong device (/dev/sda instead of /dev/sdd), deleted all partitions, made one new primary spanning over the whole device, set its type to 07 (NTFS) and hit write. So here i am with my system running. Until i reboot, i hope/guess nothing will change - meaning: all my data is accessible (I'm currently making a dd-backup of the whole device and plan to make a .tar.gz-backup of the most important data later). I also backed up /proc/partitions, /proc/diskstats (even though i guess this is more about throughput and stuff like this ...) and /sys/block/sda/sda?/{start,size}. Some further things i know: 4 primary partitions 1st partition: ~100Mb, ext3, /boot 2nd partition: ~100Mb, "Win7 Boot Partition", ntfs(?) 3rd partition: ~20...30GB, Win7, ntfs 4th partition: ~20...30GB, luks-encrypted device The luks- de crypted device is a LVM-PV The /, /home & swap-partitions are all LVs on the (VG on the) above noted PV So my questions: What is the simplest way to just write the kernels partition table to the disk? What is the simplest way to take the above mentioned (and perhaps other I don't know of ...) data and generate the partition table? Are there any problems to take care of regarding to luks and/or lvm? Is there any data I should backup before rebooting (meanig stuff from kernel [ /sys/..., /proc/...] and so on, which could help me regenerate the partition table)? Thanks a lot! P.S.: debian sid, Kernel 2.6.34-1-amd64 from debian-experimental, 80GB Intel SSD

• Computer locking up, looking for bootable hardware diagnostic tool.

  - by Carl Menke

  Well today I helped my friend build a computer. All went pretty well until we got to installing Win7. Thing is, we thought, it was crashing constantly. I adjusted pretty much every setting in the BIOS and removed as much hardware as possible to try and prevent a crash. No dice. So far I've tried running an Ubuntu live cd without the harddrive installed. Nope, crashed on boot. And then I just tried Microsoft's ram utility disk and it eventually locked up on that (the ram passed though). So it seems to me like it's either the CPU (AMD PhenomII x3) or the motherboard that could be bad, but I don't know how to test them individually for problems. I thought it could be a overheating issue, but the BIOS reports that the CPU temp is fine idling around 34C. Any advice or diagnostic disk that could help me out? TL;DR: Computer locks up frequently during use (cannot even boot/install an operating system), memory is fine, probably CPU or Mobo, BIOS says CPU temps are fine. What should I try?

• Toshiba External Hard Drive freezes computer

  - by Ephraim

  I bought a Toshiba Canvio Basics E05A032BAU2XK Portable External 320GB 2.5 Hard Drive: My computer has two Os's on it Win7 and Win XP. I need both. The main one I use is XP. When booting my computer in any OS the computer and hard drive work fine. The same holds true for plugging in the hard drive while running Win7. However, when running WinXP, if the hard drive gets plugged in the computer freezes(my main point is that the HD is portable so it is essential that it does not do this, as I said I usually run XP). After reading some online forums I was informed that there is a compatibility issue with the newest version of Eset Smart Security(I still don't understand this because it works fine in Win7 or when connected on boot...). I disabled the AV and plugged in the HD... Walla! The comnputer did not freeze. However the disk is not recognized in explorer or disk management. In device manager I removed the device and did a scan and installation of device failed. It pretty much sounds like a driver issue but I cannot find any drivers for this HD. In fact, Toshiba claims that there are no downloadable drivers for it and that XP should take care of the drivers itself. What to do? As far as I can tell, all other USB devices work just fine on both OS. Please Help!

• VNC failure on Xen

  - by BCable

  The following config works and creates a good VM in Xen: # Kernel Setup kernel = "/boot/vmlinuz-2.6.18.8-xenU" # Memory memory = "256" # Disk disk = [ "file:/opt/xen/domains/110/sda1.img,sda1,w", "file:/opt/xen/domains/110/swap.img,sda2,w" ] # container name name = "110" hostname = "boo" # Networking vif = ["type=ieomu, bridge=xenbr0"] # VNC vnc = 1 #vfb = [ 'type=vnc,vncdisplay=2,vnclisten=0.0.0.0,vncpasswd=110' ] # Behavior Settings root = "/dev/sda1" extra = "fastboot" But when I uncomment the VFB line, I get the following error after it hangs for at least 30 seconds: [root@customer 110]# xm create boo.cfg Using config file "./boo.cfg". Error: Device 0 (vkbd) could not be connected. Hotplug scripts not working. Any ideas? Part two of this question: Sometimes it actually works, and a port is opened. When this happens, nmap shows the VNC ports open and I can connect via the VNC client, but it just hangs at "Connection established." and no VNC display shows up. I've tried multiple VNC clients (TightVNC, TightVNC Java Console, RealVNC), but they all fail to connect. Does VNC through Xen require X to be started in order to function? I was under the impression that it would show the console screen, so I'm confused as to why all these issues are occurring. Thanks!

• Acer recovering windows vista

  - by Charlie Pigarelli

  My computer history is very long even of my computer has 4 years of life. An year ago I installed Windows 7 on this acer m1610 that had Vista before. My technic left me 2 recovery disc for "acer vista" before updating it to Windows 7. Then the computer had some trouble. The graphic card broke and we decided to use another computer. Yesterday I had the great idea to fuse the two computer to have a better one... So I moved the graphic card of the latter computer to the acer and everything gone well. Then the trouble of speed, it had before, come back. So I decided to reinstall the very first Windows: Vista back again. I booted the computer with those 2 DVD-R my technic left me and at the end of the process it asked me to insert "the backup cd number one or the system disk". I found 2 original Acer "Blank Recovery Disc" DVD-R and tried with those: rejected. Tried with empty DVD-+R: rejected. I tried with CDs: rejected. I don't have any system disc with me. Except for those 2 DVD-R my technic left me. What am I supposed to do now? I even tried with these fantomatic alt+f9/f10 that should start the recovery without any disc... But nothing happened. PS: the installation cannot complete if I do not insert the right disk. (The recovery disc uses Acer eRecovery Management as recovery software.

• Drobo FS vs Lime Technology unRAID vs FreeNAS

  - by elluca

  I already decided to by a drobo fs until I just found these two tests: http://www.digitalversus.com/data-robotics-drobo-fs-p889_9543_487.html http://www.digitalversus.com/lime-technology-unraid-p889_8992_473.html The two cons agains drobo for me: loudness price What disadvantages has the unraid stuff against the drobo fs? Has it also got that ease of use like swapping drives on the go, simply extend capacity by plugging in new drives, notify me of drive errors, disk failure protection, dynamic space of "partitions", better/worse effective capacity, etc. Which is more secure? Am I able to simply replace a bad drive with a new one on unraid? What happens if my pc fails? Lets say the cpu overheats. Since I have a complete pc which is going to be replaced, I only have to pay the software to use unraid. I am going to use my nas for: music library (how well does it integrate with iTunes? ) picture library movie library development (i need to be able to be to use time machine) I am going to use this nas with a MacBook pro. My current disks: 2x 500Gb 1x 1.5Tb 1x 2Tb On a drobo fs I would have 2.26 Tb of space. What would it be on unraid? Is FreeNAS also an alternative?

• ubuntu - Best way of repartitioning a (running) production server

  - by egarcia

  I've got an (externally hosted) production server running Ubuntu LTS. It serves webpages (rails) and has an svn repository accesible through Apache, and a PostgreSQL db. I've got ssh access to the server and root privileges. Most of the "interesting" stuff is located in /var/ : svn repositories are inside /var/svn, web pages under /var/www, etc. Yesterday I was curious about how much disk space had it left, so I did the following: $ df -h Filesystem Size Used Avail Use% Mounted on /dev/md1 950M 402M 500M 45% / varrun 990M 64K 990M 1% /var/run varlock 990M 0 990M 0% /var/lock udev 990M 76K 989M 1% /dev devshm 990M 0 990M 0% /dev/shm /dev/md5 4.7G 668M 4.1G 15% /usr /dev/md6 4.7G 1.4G 3.4G 29% /var /dev/md7 221G 28M 221G 1% /home none 990M 4.0K 990M 1% /tmp My 'var' partition, which holds most of the interesting part, is only 4.7G big. The /home/ partition, on the other hand, is 221G, but it is mostly unused. I should have checked the disk layout before starting installing stuff. Ideally I would need /var/ and /home/ to be "switched" - /home/ should be the one with 4.7G, and /var/ the one with 221G. Is there a way to solve this without having to reinstall the whole thing?

• Home server hard drive: 186k start-stop cycles in 325 days?

  - by j-g-faustus

  I set up a home server about a year ago, using Ubuntu server (10.04 LTS at the moment), four disks in RAID 5 for storage (WD Green 1.5 TB) and a laptop drive for the OS. Today the output of smartctl, a command line utility for checking the SMART attributes of a hard drive, tells me that the primary OS drive has had no less than 186,000 start-stop cycles in 325 days and may be nearing the end of its lifespan. The smartctl output is in "normalized values", in this case a number between 200 and 000, where 200 is "brand new" and 000 means "worn out". My disk gets 001. So I wonder what happened: 186k start/stop cycles in 7820 hours is about one start/stop per 2.5 minutes around the clock. This seems somewhat excessive for a computer that sees actual use once or twice per day. (The RAID disks are normal, averaging to one start/stop per day, as expected.) Does anyone have similar experiences, or pointers to what might be the issue here? Specifically I'd like to know Why the massive start/stop count? Do I have some sort of configuration issue? Could there be a background service that is causing trouble? Could having a laptop disk as the OS drive be part of the problem? Can anyone confirm or deny this? Here is the /etc/hdparm.conf configuration /dev/sda { apm = 127 spindown_time = 120 } and the most relevant parts of smartctl --attributes /dev/sda: smartctl version 5.38 [x86_64-unknown-linux-gnu] Copyright (C) 2002-8 Bruce Allen === START OF READ SMART DATA SECTION === SMART Attributes Data Structure revision number: 16 Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 1 Raw_Read_Error_Rate 0x002f 200 200 051 Pre-fail Always - 0 4 Start_Stop_Count 0x0032 001 001 000 Old_age Always - 185875 9 Power_On_Hours 0x0032 090 090 000 Old_age Always - 7820 12 Power_Cycle_Count 0x0032 100 100 000 Old_age Always - 109 193 Load_Cycle_Count 0x0032 118 118 000 Old_age Always - 246833 194 Temperature_Celsius 0x0022 107 098 000 Old_age Always - 36 As I generally prefer my drives to last more than a year, any advice is appreciated.

• Very slow browsing shared folder XP client/host

  - by Ickster

  I have a pretty straightforward setup where I'm storing media files on an XP pro machine, and sharing the folder to be accessed by other XP pro machines around the house. (Typically, there's only one client accessing the share at a time, although there may be several with the share mounted.) It's been working just fine for years, but I've recently started having some problems. A couple of days ago, the host PC had power disconnected while it was running. It was restarted and everything seemed fine initially, but since then browsing the shared folder from client machines has been extremely slow and actually reading data is all but impossible. The problem exists in every access method I've tried: Windows Explorer, VLC dialogs, command line, etc. My first thought was that the disk was experiencing problems, but there are no problems viewing the files locally on the host machine. My second thought was that there was a network problem on the host machine, so I removed and reinstalled drivers for the NIC with no change. My third thought was that there might've been a problem elsewhere on the network, so I swapped out hardware to no avail. I'm regrouping and trying to come up with a methodical approach to figuring out what might be wrong. I would of course be thrilled if you can suggest specific problems (Microsoft KB articles, etc.) that I might check, but I'm not expecting a silver bullet. If you can help me outline an approach to identify the problem (including recommended tools, e.g., disk checkers, network analyzers, etc.) I'd greatly appreciate it.

• Missing boot files in Windows 8

  - by Alex F. Sherman

  I had a partition with Windows 8 Release Preview, Windows' System Reserved partition and the empty space of the beginning of disk. I moved two partitions to the beginning of disk using Ubuntu Live CD and GParted. After that, the Windows Loader didn't boot and throw an error about missing files. I fixed it using the commands: bootsect /nt60 sys /force /mbr bootrec /rebuildbcd bootrec /fixboot bootrec /fixmbr When I used "Automatic repair" option from "Advanced boot" menu, it throw an error like: Windows can't fix your boot problems. For more information see file C:\Windows\System32\LogFiles\Srt\SrtTrail.txt In this file I found a description of the system repair actions and at the end of file: Boot status indicates that the OS booted successfully. Now, when I use the Advanced boot menu from Windows 8 (PC settings - General - Advanced startup) I receive an error: Restart your PC to try again. It looks like something didn't load correctly. Restarting might fix the problem. If this happens more than once, you might also be able to find help by searching online for the specific error code. Erorr code: 0x8007090. 0x80070490 is the error code ERROR_NOT_FOUND. What are the missing boot files and how can I restore them? List of files in System Reserved Partition: B:\bootmgr B:\BOOTNXT B:\Boot\BCD B:\Boot\BCD.LOG B:\Boot\BCD.LOG1 B:\Boot\BCD.LOG2 B:\Boot\BOOTSTAT.DAT B:\Boot\Fonts B:\Boot\memtest.exe B:\Boot\qps-ploc B:\Boot\Resources B:\Boot\Resources\bootres.dll and many *.mui and *.ttf files.

• Software mirroring (RAID1) versus "Fake Raid" for new Windows 7 install

  - by kquinn

  I've just ordered two new hard drives for my main desktop and a copy of Windows 7 Professional 64-bit. I'd like to do a clean install of Win7 onto the new drives (leaving my old XP Pro boot partition around for a while in case something goes disastrously wrong, etc.). I want to have them set up in mirrored (RAID-1) mode. My understanding is that Win7 Pro can do software mirroring, but can I set this up directly at install time? If so, how? Note that I'd like the disk to be split into three partitions (OS/Apps&Data/Bulk data), all of which should be mirrored. Would it be better (more reliable or faster) to use my motherboard's hardware RAID support? My motherboard is an older nVidia nForce 680i SLI, which is not the most stable of motherboards, and I'm not sure how trustworthy its RAID1 configuration might be (or if Win7 could even detect and install onto a hardware-mirrored volume). Also, the performance characteristics of RAID1 are rather different than RAID0 or RAID5, and I'm wondering if Win7's software mirroring might actually be faster than hardware RAID1 (for example, I'm more of a Unix admin when I have to wear the sysadmin hat, and I've had great success deploying ZFS; most hardware RAID1 implementations have to read both disks and compare results to look for data errors, but ZFS can read from only one disk in the mirror and just use the built-in checksum, meaning it can have up to 2x the number of reads in-flight, as long as there's no data corruption). Edit: Okay, my question about whether Windows 7 can do software mirroring has been answered, and it can. I'm still unsure whether Windows software RAID or my motherboard's hardware "fake RAID" function is a better choice, though. Remember, I'm only interested in mirroring -- not the more complicated striping or parity operations that generally show the poor performance of crappy motherboard RAID solutions.

• What do you upgrade to make games load faster? [on hold]

  - by Superbest

  Let's say you have a relatively modern game like Shogun 2. The loading screens take several minutes. This bothers you and you'd like to improve it. What is actually going on when loading screens are up? I'm guessing assets are being loaded into memory from disk, and possibly being decompressed first. However, what is actually causing the slow down? The memory? Mainboard? CPU? HDD? If you had $100 to spend on upgrades and your only goal is to speed up loading screens without reducing other performance, what component of the computer does it make sense to upgrade for maximum benefit? If your answer is "it depends on the existing setup", what sort of benchmarks would you run to determine what is causing the bottleneck? What if you had $500 instead? I give the two budgets for context. I am not asking for actual recommendations about which component to buy (nor are the numbers supposed to be rigid limits), but what features are important when shopping for components with small and large budgets (a large budget could allow buying multiple components which are not so good on their own, but work particularly well together). I mention Shogun 2 as an example, but I'm asking about reducing overall loading times, across all games, not just one game. Therefore, "put it on a solid state disk" probably won't be good solution, because putting every game on your SDD will quickly fill it up.

• Dual boot windows 8 pro and windows 7 on XPS 8500 Special Edition

  - by Jesse

  I am trying to install a dual boot with windows 7 premium and windows 8 Pro on an XPS 8500 special edition. I created a new primary partition on my C: drive, inserted the windows 8 install disk, and rebooted my computer from DVD. I select custom install and the dialog box saying "Where do you want to install windows at?" pops up but none of my drives are listed. Please help me determine what is going on. I don't understand why none of my drives are showing up on this menu. Not even the original drive. When I go to load driver and click on the partition I created it tells me "No signed device drivers were found. Make sure the installation media contains the correct drivers, and then click OK." resolved above issue by running setup from the source folder on the install disk instead of booting from DVD. Was able to locate my new partition and start install. It completes the first step of "Copying windows files" just fine but then on the next step "Getting files ready for installation" my computer restarts and attempts to load windows 8 but keeps telling me my pc needs to restart. This keeps going on in an infinite boot loop. Please help, this has been a nightmare!
