• Dual HDD dual boot Win7/Win7 hibernate corrupts partitions?

  - by Ivan Zlatev

  I have two SSDs in my laptop. Both have 2 partitions each one with Windows 7 64bit and another one with OEM stuff on it (SYSTEM_DRV). I use the BIOS boot menu to boot between the drives. I have removed the drive letters so that no partitions of drive 1 are mapped in windows 2 on drive 2 and wise-versa. What I have observered however is that when I hibernate windows 1, boot windows 2 do some work and shutdown then resume windows 1 - the windows 2 partition will get corrupt quite often. Just happened actually - it is shown as "RAW" in the Disk manager instead of NTFS and windows will blue screen at boot. Alternatively I've seen cases where chkdsk will run and will wipe out all security descriptors making the partition completly unbootable. Why am I seeing these corruptions and what can I do to prevent them?

• Options for transparent data encryption on SQL 2005 and 2008 DBs.

  - by Dan

  Recently, in Massachusetts a law was passed (rather silently) that data containing personally identifiable information, must be encrypted. PII is defined by the state, as containing the residents first and last name, in combination with either, A. SSN B. drivers license or ID card # C. Debit or CC # Due to the nature of the software we make, all of our clients use SQL as the backend. Typically servers will be running SQl2005 Standard or above, sometimes SQL 2008. Almost all client machines use SQL2005 Express. We use replication between client and server. Unfortunately, to get TDE you need to have SQL Enterprise on each machine, which is absolutely not an option. I'm looking for recommendations of products that will encrypt a DB. Right now, I'm not interested in whole disk encryption at all.

• Windows 8 Unable to perform hibernate

  - by Jones

  Windows 8 Enterprise edition x86. Already enabled hibernate option, to have it on shutdown menu (start menu?) and set to hibernate on lid closing. However it's not hibernating for me. When I'm trying to sleep, it's sleep fine and wake up like a kid. But when I'm demanding hibernate, it disconnects internet, turn off screen and be back to lock screen in one second. Steps I've tried. Complete shutdown Clear hiberfile.sys by disabling and enabling back Resetting my power settings. Causes I suspect: Had dual boot with BackTrack with Windows 8 GUI boot manager. It was fine until I reinstall BackTrack, bootmgr resetted and I'm in Ubuntu boot menu;. Using additional hard disk through USB cable.(But it's not a problem before few days, however) How to make my system to hibernate and wakeup again.

• Ubuntu dual boot and grub error 18

  - by srboisvert

  I've attempted to install 9.04 on an older toshiba laptop with a new 300GB drive and am getting the dreaded Grub error 18 that indicates that grub is looking beyond the bios readable area of the HD and failing. I just let ubuntu roll with its default selections when installing and ended up with this: Drive layout /dev/sda1 -ntfs 128GB -boot /dev/sda2 -extended 170GB -lba /dev/sda5 -ntfs 167.59GB /dev/sda6 -ext3 2.33GB /dev/sda7 -linux-swap 172MB I'd like make the system dual bootable without having to reinstall windows (real pain since I would have to go through an obstructionist IT dept). I know I can make windows bootable with a rescue disk and fixmbr but is there something I can do to make it dual bootable using the ubuntu livecd? Alternately, what should I have done at the partition stage of ubuntu installation to avoid this?

• mount fstab partition with public access

  - by Mikhail

  How do I specify that an fstab mount-point should be public? I want /mnt/windows to be accessible to normal users. I believe I am using ntfs-3g. If I set the /mnt/windows to 777 will it be publicly accessible without changing the permissions on the NTFS disk? /dev/sdb4 /mnt/windows ntfs noatime 0 1 /dev/sdb5 / ext4 noatime 0 1 UUID=5AA4-168D /boot/efi vfat defaults 0 1 and localhost my_computer # stat /mnt/windows/ File: '/mnt/windows/' Size: 12288 Blocks: 24 IO Block: 512 directory Device: 814h/2068d Inode: 5 Links: 1 Access: (0700/drwx------) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2014-08-21 18:29:13.597722200 -0500 Modify: 2014-08-21 18:29:13.597722200 -0500 Change: 2014-08-21 18:29:13.597722200 -0500 Birth: -

• 32 vs 64-bit software for same machine?

  - by GorillaSandwich

  What is the difference between 32 and 64-bit software? My understanding is that 64-bit can use more RAM, if it's available, because it has a larger address space for it. Is this correct? And, specifically: If I have a 64-bit operating system with lots of RAM, and I install, say, the 32-bit version of MySQL instead of the 64-bit version, will it be unable to use all the available RAM and therefore run slower than the 64-bit version might on the same machine (assuming RAM becomes the bottleneck before processing speed or disk access speed or whatever)? If I have a 32-bit operating system and I install a 64-bit piece of software on it, will it (probably) fail to run?

• Clicks or ticks every minute when HDD is idle [closed]

  - by Ramy

  Possible Duplicate: Clicks or ticks every minute when HDD is idle My HDD is a My passport... It's 2 weeks old. I hear this tick or click followed by another one about 8-9 secs later, and they repeat every minute almost exactly... They usually happen and the LED light blinking.. It's not like the other clicks you hear that indicate any inevitable HDD failure, it's much lower in volume. I don't know what that is, however it's different than the rest of the HDD usual sounds...It's close to the sound of the mouse click. It sometimes also happens when I access a file on the drive mostly after being idle for a while, sometimes randomly not really sure... The drive though is working well, the SMART report comes out OK and without warning, and disk management shows it healthy... What could be the cause of this??

• (Preferably) Encrypted Server Backups

  - by Shoaibi

  I have somehow managed to purchase a VPS after collecting money for sometime, now problem is i cant find a way to backup the server. My previous approach was: Got a webdav account from mydisk.se, mounted it on the vps, used duplicity and created encrypted backups. Problem is it was only 2G, and its running out of space, at my own place i dont have a stable internet connection else i have a 500G drive that i could surely use for backups. The vps has a 12G HD, and i would like to backup /home, /root, /etc, /var/ (specially log and www). Any ideas are welcomed. [EDIT] I am more of looking for resource of setting up a backup-point or such(i know how to setup a backup server, but i cant as i dont have stable connection or the money to buy another VPS/disk for backup) , i have already got the tools needed.

• Outlook 2010: using signatures stored on network

  - by Gregory MOUSSAT

  With Outlook before the 2010 version, it was possible to specify any path for the signatures. With Outlook 2010, the only way is to use those stored into C:\Documents and Setting\UserName\Local Settings\Application Datas\Microsoft\Signature\ I'd like to point the signatures to a network share. Allowing us to modify the signatures into the share, instead of login on every computers each time we are asked to modify them (and this is quite often because the signatures contain logos about current events). We currently use a script to copy the signatures from the share to the local disk when users login. Question: How to set Outlook 2010 to use signatures outside of the default signature folder ?

• Best practice for scaling a single application source to multiple nodes

  - by Andrew Waters

  I have an application which needs to scale horizontally to cover web and service nodes (at the moment they're all on one) but interact with the same set of databases and source files (both application code and custom assets). Database is no problem, it's handled already with replication in MongoDB. Also, the configuration of the servers are the same (100% linux). This question is literally about sharing a filesystem between machines so that its content is always correct, regardless of the node accessing it. My two thoughts have so far been NFS and SAN - SAN being prohibitively expensive and NFS seeing some performance issues on the second node with regards to glob()ing in PHP. Does anyone have recommended strategies or other techniques that don't involved sharding data across nodes or any potential gotchas in NFS that may cause slow disk seek times? To give you an idea of the scale, the main node initialises it's application modules in ~ 0.01 seconds. The secondary is taking ~2.2 seconds. They're VM's inside a local virtual network in ESXi and ping time between them is ~0.3ms

• CPU fan turns on and off repeatedly without booting

  - by rnso

  My PC has suddenly stopped starting up. On checking with case open, the CPU fan starts running when the power is turned on, but it stops after about 2-3 seconds, restarts again after about 2-3 seconds and the loop is repeated. There is no beep and nothing appears on the screen. On searching the internet, I found there could be several reasons for this. I tried removing hard-disk, CD drive, tightening connections etc but of no avial. I also tried using a new power supply but the response is the same. Where could be the problem and how can it be solved? Thanks in advance.

• Linux: don't use file system cache under a directory

  - by GetFree

  For a PHP website I'm monitoring, I need to see what files are being used each time the browser makes a request. I thought of using find . -type f -amin 1. With that I get all files which were read in the last minute (it's a developing server so only I am using the website). I took care of removing the noatime attribute from the mounting point. However there must be something else that's preventing the kernel from reading the actual files on disk because the access time is not being updated when I read a file. I guess it must be the file-system cache which is retrieving the files from memory. Is there a way to disable file caching under a specific directory? (public_html in my case) Also I read somewhere that there is the nobh mounting atributes which apparently disables file caching under that mounting point, but I'm not sure.

• Software that will burn DVDs with a SFV or Pararchive file for each disc?

  - by Matt

  I'd like to burn several thousand RAW files (.DNG) of around 10-30 MB each to DVD to backup my photo archive. I'm looking for software that can do this and include an SFV-type file on each disc burnt. These are my requirements: compression is optional, and probably not desirable due to the extra time involved files should be spread amongst the discs as self-contained units, i.e. I don't want to have to load files from more than one disc to be able to read the files on that disc, so that excludes WinRAR's spanning options I don't want to spend time writing ISO images first as this will be a task I'll need to repeat often as I add new images to my archive - the software should write to the DVDs for me as simply as possible I'd like the SFV/Pararchive/recovery record to be stored with the files on each disc, so it only references the files on that particular disk Thanks in advance!

• Brand new Seagate HDD has high raw read error rate

  - by kpax

  I've just purchased a brand new Seagate ST31000524AS 1TB HDD. Manufacture date shows as January 2012 (yes that's as new as new can get), so must be one of the new batches from the post-flood Thailand. Anyway, I downloaded a copy of Active Hard Disk Monitor tool to check the S.M.A.R.T. parameters and I find the parameter Raw Read Error Rate is very low. Should I be worried? Will this rectify over time? This hdd is just 7 hours old; what gives? Edit: I meant high raw read error rate - Title updated accordingly

• Why does diskpart set the volume attributes on all volumes?

  - by Nick

  I was trying to migrate a Win7 OS from a HDD to a SSD. I've created 2 partition with 1024KB offset, with diskpart: 100MB System Reserved and a 60GB for C:. I've cloned their contents using Easeus Disk Copy. I've loaded the Windows 7 Boot DVD, and wanted to use diskpart to drop the letter for the System Reserved partition and make it hidden. select volume 0 detail volume attribute volume set nodefaultdriveletter attribute volume set hidden These 2 attribute set commands actioned on both volumes (0 and 1, MSR and C:) instead of the selected one, and viceversa. I've tried to clear these attributes from volume 1, but it cleared them also from volume 0. Why does DiskPart have this behaviour?

• Installing linux mint in one partition

  - by sha404

  So, I have a disk with a MBR setup(image below). I've managed to have 50 GB unallocated space for intalling Linux Mint 14. And I want to keep the current windows OS too(but don't want the Mint inside windows). Now I've seen in some tutorials that Linux Mint needs several partitions for bootloader, swap, & home. I don't like to have so many partitions & maybe MBR stuff won't let me create more than one now. So, is it possible to install Linux Mint in one partition only? If it is really impossible than what's the minimum number? & how can I accomplish that? Thanks in advance.

• my WD Mybook wd5000h0032 is DEAD?

  - by Herudae

  Hello, i have a WD Mybook Premium (wd5000h032) it used to work just fine but suddenly i can't access to it. The blue lights turn on but the drive doesn't start, it makes no click, nor any other sound, it just like if it was disconnected from USB, of course my PC doesn't detect it, i've tried with trhee different USB cables two PCs and one laptop and nothing. Is it really dead? how can i recover the information stored there? i think the problem could be the case, if so, could i take out the disk and connect it as an internal drive? or could i buy another case?

• Which software to use for RAMDISK on Windows 2008?

  - by Tony_Henrich

  I am building a server machine with lots of RAM. At least 16G. I am planning to put my frequently read and written data in RAM so I am looking for software for creating RAM disks. This is for Windows Server 2008 R2 Standard 64bit. Any recommendations? I would like one where I can flush the disk image into persistent storage upon demand. For example when Windows shuts down. (I am aware of all the consequences of data loss when power is lost)

• Putting our OLTP and OLAP services on the same cluster

  - by Dynamo

  We're currently in a bit of a debate about what to do with our scattered SQL environment. We are setting up a cluster for our data warehouses for sure and are now in the process of deciding if our OLTP databases should go on the same one. The cluster will be active/active with database services running on one node and reporting and analytical services on the other node. From a technical standpoint I don't see an issue here. With the services being run on different nodes they shouldn't compete too heavily for resources. The only physical resource that may be an issue would be the shared disk space. Our environment is also quite small. Our biggest OLAP database at the moment is only about 40GB and our OLTP are all under 10GB. I see a potential political issue here as different groups are involved but I'm just strictly wondering if there would be any major technical issues that could arise from this setup.

• Ubuntu hang, and cannot be soft-reset after resuming from stand by mode

  - by Phuong Nguyen

  I have downgrade my xorg drivers, so I can hibernate and stand by my ubuntu smoothly. However, in some case, there's a problem. My ubuntu get hang. When I tried to switch to console mode (Ctrl+Alt+F1), then I cannot login. The system always reply with an error whenever I tried to press a key. When I press Ctrl+Alt+Del to perform a softreset, here what's it said: [80141.320122] end_request: I/O error, dev sda, sector 193687181 init: control-alt-delete main process (5660) terminated with status 2. This error is not even recorded in syslog. I guess this should be a problem with my hard disk since it said something about a bad sector. Exactly, what kind of error is this?

• DDRescue on Windows or another options like DDRescue for Windows

  - by Frank Thornton

  I have a drive with failed sectors ect... I can't image it with Acronis as it hangs. I can't with Knoppiz it hangs. CHKDSK hangs. I want to use DDRescure but I don't have any Linux boxes running at the moment. I could do is in a VM but that seems like it would be slow and problematic? Are there any ways I can data recovery this disk from my Windows machine or is there an ideal way to work with DDRescue on Windows?

• Snow Leopard Hangs at Login Window

  - by jessecurry

  I've had an issue for the past few months, but I rarely restart so it hasn't caused too much trouble. Basically, when I start up my Mac (iMac10,1 - 3.06GHz Intel Core 2 Duo, OS X 10.6.3) everything proceeds as usual until I reach the login window. The login window displays normally, but keyboard and mouse input seem to be ignored. This condition persists for around 5 minutes at which time everything goes back to normal. While the login window is frozen my second monitor appears entirely blue, the second monitor receives a background as soon as the login window becomes responsive. If I startup while holding SHIFT the problem still occurs, but the freeze is much shorter. Looking through my logs I see no activity during the time that the login window is frozen. I've attempted to repair disk permissions, and gone through every possible maintenance option in Cocktail.

• My 4 GB microSD card only allows me to use 1 GB

  - by James Litewski

  My phone came with a 4 GB microSD card. On the card it lists that 3 GB goes to Muve Music which is Cricket's music program, and I get 1 GB... Well, I don't pay for Muve Music, so why waste the space? I thought I'd be able to simply buy an adapter and reformat the microSD card to get the full 4 GB; but that wasn't the case... I could only find the 1 GB partition on the card. I even tried reformatting the disk, but I had no luck. How can I get the full 4 GB? BTW, I'm running Mac OS X v10.7 (Lion).

• Resize ntfs system partitions with GParted?

  - by ane

  Trying to resize 2 ntfs system and boot partitions (windows 2003 server) using GParted. Goal: Resize D: (/dev/sda1) to ~850G - this is the boot drive with D:\ntldr, boot.ini, etc. Resize C: (/dev/sda5) to 100G - this is the system drive with C:\windows Tried resizing /dev/sda5 first and got the chkdsk error shown in screenshot #2. (You must run chkdsk /f). Have already run chkdsk /f on C: multiple times with no bad sectors or errors found. Have also run multiple chkdsk /f's on the underlying hard disk multiple times and rebooted way more than a couple times with the same error. How do you force gparted to ignore this error and resize? I found there is --force option to ntfsresize but don't know how to get the GParted ISO live CD to use it. How do you move the unallocated space so an extra ~750G is to the right of /dev/sda1 (D:), and an extra 10G to the right of /dev/sda5 (C:)

• how to restore grub

  - by takeshin

  During copying files via lan my Ubuntu Server 10.04 hung up and I had to reset the computer. After reboot, I got: Grub error 17, so I tried the rescue alternate CD, but I got a info, that no partitions were found on the disk. I used testdisk to restore the partitions. Using fdisk -l shows the partitions now, but when the system boots up I does nothing but displays: L234: When I plug the drive to another computer, it is not automatically mounted and I can't access the data. What to do now? How to restore the grub and boot up the system?
