• Bad Blocks Exist in Virtual Device PERC H700 Integrated

  - by neoX

  I have a DELL server with PERC H700 Integrated controller. I've made RAID5 with 12 harddrives and the virtual device is in Optimal state, but I receive such errors under linux: sd 0:2:0:0: [sda] Unhandled error code sd 0:2:0:0: [sda] Result: hostbyte=0x07 driverbyte=0x00 sd 0:2:0:0: [sda] CDB: cdb[0]=0x88: 88 00 00 00 00 07 22 50 bd 98 00 00 00 08 00 00 end_request: I/O error, dev sda, sector 30640487832 sd 0:2:0:0: [sda] Unhandled error code sd 0:2:0:0: [sda] Result: hostbyte=0x07 driverbyte=0x00 sd 0:2:0:0: [sda] CDB: cdb[0]=0x88: 88 00 00 00 00 07 22 50 bd 98 00 00 00 08 00 00 end_request: I/O error, dev sda, sector 30640487832 sd 0:2:0:0: [sda] Unhandled error code sd 0:2:0:0: [sda] Result: hostbyte=0x07 driverbyte=0x00 sd 0:2:0:0: [sda] CDB: cdb[0]=0x88: 88 00 00 00 00 07 22 50 bc e0 00 00 01 00 00 00 end_request: I/O error, dev sda, sector 30640487648 But all disk are in Firmware state: Online, Spun Up. Also there is not a single ATA read or write error in any disk in the raid (I check them with smartctl -a -d sat+megaraid,N -H /dev/sda). The only strange thing is in the output in megacli: megacli -LDInfo -L0 -a0 ... Bad Blocks Exist: Yes How could there be bad blocks in a Virtual Drive, which is in optimal state and no disk is broken or even with a single error? I tried "Consistency Check", but it finished successfully and the errors are still in dmesg. Could Someone help me to figure it out what is wrong with my raid?

• How to lock Windows7 from installing anything.

  - by Andy

  A family member continually needs me to reinstall his PC after it gets viruses and spyware. He claims that he never downloads anything but evidence suggests otherwise. Unless there is some way that watching 'videos' can get spyware on there. AFAIK the computer is kept up to date. Possible solutions? Make a login where its impossible for him to install anything. Windows 7 standard account doesn't appear to be enough. Is a standard account enough here? I tried this once before and he still seemed to get IE toolbars installed up the wazoo Somehow make an automated image where if he 'messes up' or even on log off the computer restores the whole drive image. Similar to what I've seen in Kinko's Something I've not thought of.... And I know you are all going to say 'stop fixing it you are an enabler'... yes I know but I'm not going to have another fight with my wife over helping her family... right now I'm doing this to keep her happy not the idiot with the 'video' addiction ;-) So the name of the game is minimizing my overhead.

• How can I set my bootloader to load my primary (C:) partition?

  - by acidzombie24

  I created 4 partitions and want to use them to have seperate Windows XP, Windows 7, (possibly) Windows Vista installations, and "WinDummy" (to test applications in Vista, XP or another OS). I used Norton Ghost to install an OS to the drive in about 3 minutes. My problem is that I installed the spare first on the 4th partition, then Windows 7 on the second. I tried to set the bootloader (with easybcd) to use the first partition - but it doesn't want to. Heres my debug screen on easybcd As you can see, the device is set to H and i cant figure out how to change it. I can make my bootloader use Windows 7 first, but I can't make it use my C: install of XP instead of my spare H:. How would I fix this?

• How do I improve my incremental-backup performance?

  - by Alistair Bell

  I'm currently using the traditional rsync+cp -al method to create incremental/snapshot backups of our server tree. The backups are going onto a pair of eight-disk towers connected to the backup machine (a Sandy Bridge machine with 16 GB of RAM, running CentOS 5.5) via four eSATA connections (four disks per connection). Each disk is a regular 2 TB disk, so we have 32 TB of disk space connected to the backup machine. We're backing up about 20 TB of data on the servers with this. The problem is that each daily backup is taking more than 24 hours, and the real time-killer isn't the actual rsync, but the time it takes to perform a cp -al of the tree locally on the backup machine. It's taking more than 12 hours just to make the shadow copy of the tree, and as far as I can tell the performance backlog is at the disk (top shows the cp using a lot of RAM but not a lot of CPU and mostly in uninterruptible-sleep state) We have the server data split into four major volumes (and a few minor ones), and each of these backups runs in parallel (with some offsets in the cron to try to get some disks' cp done first). There are two volumes on the backup drive, both striped LVM volumes of 16 TB each. So obviously I need to improve the performance because it's unusable as it stands. The first question is: when CentOS 6 comes out, with support for btrfs, will making snapshots of subvolumes with btrfs substantially increase this performance? The second is: is there a way, with ext3 or something else supported in CentOS 5 or 6, to 'encourage' it to put the directories/inodes in one part of a volume (which could happen to be the part that's on an SSD, via LVM) and the files in another? That would presumably solve the problem, but I don't know of ways to hint ext3 like that.

• Cannot connect to local network shares when connected to VPN. Error: "the user name could not be found"

  - by Nick G

  I keep finding that on our small company LAN (7 users, 3 servers) that some servers keep becoming "not accessible" for the purposes of file sharing. They display the message "\SERVER is not accessible. You might not have permission to use this network resource. The user name could not be found". But I don't know why "the user name could not be found" as all the machines are on the same domain and the PDC and BDC seem to be behaving OK. EDIT: VPN seems to be the cause: It turns out I can see the server if I use the IP address (\\1.2.3.4\ etc) or the FQ active directory name (eg \server.domainname.local) but not if I use the server name on its own or a mapped network drive originally created from the "short" name. Oddly though, my machine has no issue resolving the server's DNS name as I can ping the machine name OK and it immediately comes back with the IP, however nslookup seems to fail. It seems to be a problem with how Windows looks up machine names when connected to VPNs. When I'm connected to a VPN, windows seems to use the DNS assocated with the VPN and not the one on the domain controller. This behavior to me, seems incorrect as surely that would mean connecting to any VPN would break any ability to lookup local machine names for servers and printers etc. So I guess the real question now is, how can I make my machine still search the local Active Directory DNS (the PDC) even when connected to a VPN? More info in my comments below.

• How to stop SophosAV from scanning directories under source control

  - by user26453

  From googling it seems its well known that SophosAV as well as other AV programs have issues with how they interact and can inhibit source control utilities like TortoiseHG or TortoiseSVN. One solution is to exclude directories under source control from on-access scanning as detailed here on Sophos's support site. There is a corollary article that mentions some issues related to this, namely need to place multiple entries for exclusions based on the possibility of the location being accessed through the short vs. long name (e.g., Progra~1 vs. "Program Files"). One other twist is I am using a junction to relocate my user directory, C:\Users\Username, to a second hard drive, E:. Since I am not sure how this interacts I have included the source control directory as they are nested in both locations. As a result, I have included the two exclusions for the on-access scanning exclusions (and to be on the safe side on-demand exclusions as well, although this should only come into play when I select a parent directory of the exclusion to be scanned on-demand, but still). You'll notice I have no need to add extra exclusions for those locations based on short vs. long name distinctions. The two exclusion I have then, for both on-access and on-demand scanning exclusions are: C:\Users\Username\source-control-directory E:\source-control-directory However, this does not seem to work as TortoiseHG still lags terribly in response to any request as AV software starts scanning when the directory is accessed via TortoiseHG. I can verify without a doubt that Sophos is causing the problems: I can completely disable on-access scanning. Once this is done TortoiseHG responds very fast to all operations. I cannot leave this disabled obviously, but since the exclusion don't seem to be working, what next?

• Visual Studio 2012 Very Slow Typing

  - by DaoCacao

  I have a problem. After SP1 update, passing some time, VS 2012 becomes very-very slow when typing text. Solution size is not big, PC is quite powerful, it has 16GB of RAM, SSD drive, and i7-2600. I have attached using another VS and I see in debugger a lot of exceptions: First-chance exception at 0x753BB9BC in devenv.exe: Microsoft C++ exception: CVcsException at memory location 0x0027DF0C.

• SAS vs Near-line SAS vs SATA

  - by David

  I'm unsure about the differences in these storage interfaces. My Dell servers all have SAS RAID controllers in them and they seem to be cross-compatible to an extent. The Ultra-320 SCSI RAID controllers in my old servers were simple enough: One type of interface (SCA) with special drives with special controllers, humming at 10-15K RPM. But these SAS/SATA drives seem like the drives I have in my desktop, only more expensive. Also my old SCSI controllers have their own battery backup and DDR buffer - neither of these things are present on the SAS controllers. What's up with that? "Enterprise" SATA drives are compatible with my SAS RAID controller, but I'd like to know what advantage SAS drives have over SATA drives as they seem to have similar specs (but one is a lot cheaper). Also, how do SSDs fit into this? I remember when RAID controllers required HDDs to spin at the same rate (as if the controller card supplanted the controller in the drive) - so how does that work out now? And what's the deal with Near-line SATA? I apologise about the rambling tone in this message, it's 5am and I haven't slept much.

• How do I install OpenStack on a single Ubuntu 12.04 node?

  - by Sam Edwards

  I'm having trouble installing OpenStack in Ubuntu 12.04, for various reasons: The official Ubuntu website recommends Juju and MAAS. However, this is a single node I am trying to get OpenStack installed on, and MAAS requires "two or more nodes" according to the docs. Additionally, I don't have any experience in MAAS and Juju and would rather stick to technologies I am more familiar with so that I can debug problems that arise. I have tried StackGeek but this fails because the node only has a single Ethernet port. The node does, however, have the second hard drive required for the nova storage. I have tried DevStack but cannot log into the dashboard. The login form appears fine, but as soon as I try to submit the page, my browser begins loading indefinitely. I have tried installing straight from packages, but I get an Internal Server Error in the dashboard upon trying to log in, with no helpful logs anywhere in sight to aid me in debugging the issue. Each of these attempts was with a fresh Ubuntu 12.04 LTS setup; I'm finding it really strange that no matter what I try, I cannot get OpenStack installed. Is this even a stable/mature project? Why am I encountering so many bugs?

• Update to Lion, Cannot boot into Bootcamp partitions, but can use in Parallels

  - by Jon Jester

  Using Snow Leopard had boot camp partitions for both XP and Windows 7. These were both accessible through Parallels 7 or through direct boot through boot camp. Each is on a separate partitioned hard drive. Upgraded to Lion, both were still accessible through Parallels, but have not been able to directly boot into either. Unfortunately is important to me to be able to boot into a least the Windows 7 partition. Have tried virtually everything I can find online. Seen similar issues, but nothing where they were usable virtually but not directly. Nothing works. reFit, correcting the master boot records in Windows with command line, have wiped the Windows 7 partition clean and reinstalled Windows 7 several times 1st using Boot Camp4 drivers then using Boot Camp3 drivers. Have tried resizing the bootcamp partitions. When booting into the Boot Camp partitions directly will go all the way to seeing the desktop before it fails, where I get a Windows error screen. I can see all the disks and their appropriate partitions both in OS X disk utility as well as the Windows installer utility.

• Verification of files on backup media - after the backup

  - by Greg Sansom

  I have a system in place where I back up my work files daily to a portable hard drive. I actually have two portable hard drives - one is stored off-site and I swap them regularly. I also keep my family photos and other historical files backed up, but I only back the photos up occasionally (ie when I have new photos). The backup media is for backup only, and it is unlikely I will ever read the files from the backup media unless a disaster occurs and I lose the master. It worries me that my backed up files could become corrupt without me knowing it. It is also feasible that my master files could become corrupt, and eventually the corrupt files would be replicated to the backup media. I'm currently using Cobian Backup, but I'm open to alternatives. Is there a tool I can use to confirm that the backed up files are identical to the files that were first copied? I know it would be possible to generate a checksum and periodically validate the backup files against the original checksum, but I'm looking for a tool which will do this automatically.

• Embedded Spotlight does not function in Outlook 2011

  - by syntaxcollector

  I have a rather strange problem. I manage a network of about 35 Mac, and we all recently switched from Mail.app to Outlook 2011 (Please don't debate this, I've already had this conversation ad nauseum) We are using network home directories (NHD) server from a Windows file server over the SMB protocol. The problem I'm having is Spotlight does not function inside of Outlook. But ONLY inside of Outlook. The global Spotlight can find all email and contacts with Outlook, but the embedded Spotlight cannot. As a test, I took one of my users and switched them from a network home directory to a portable home directory (PHD) (this means the home folder was copied to the local hard drive). This resulted in a working Spotlight within Outlook, as soon as I switched the user back to an NHD, however, it stopped working. I have already tried erasing the Spotlight index and killing the process to force re-indexing. I have exhausted all Spotlight troubleshooting, and since the global is working that is obviously not the issue. I believe it has something to do with the Spotlight plugin Microsoft wrote that is located in /Library/Spotlight. Any ideas?

• Xbox 360 formatting for MP4 h.264?

  - by Kayle

  For the life of me, I can't get the Xbox 360 to recognize anything other than a WMV. It's full updated with Xbox Live and I even added all the Video apps (Zune, Netflix, etc) just to see if it would force some sort of codec update. I'm using handbrake, at the moment, to try and convert an mkv with subtitles. Handbrake burns the subtitles into the video for me, which is important. I can't figure out what is missing though, as the Xbox refuses to acknowledge my MP4s. Here's the VLC codec info output: As far as I can tell, this is EXACTLY what the xbox supports. I don't want to convert every video twice by throwing it through Windows Movie Maker just to get it to WMV. None of the converters mentions above output to WMV and I don't like WMV since it's not as universal as MP4. I've tried changing the container name manually to M4V, MOV, and AVI to see if I can trick the Xbox... no beans. The video displays perfectly in WMP, of course. If I convert it to WMV, suddenly it works fine. But I don't find this acceptable, as I know the Xbox is supposed to support other filetypes. If anyone knows why my Xbox won't play anything but WMVs, I would be very appreciative to know why! It's driving me nuts. The only other information I can think to include is that it's about 3 years old and of the cheapest variety (Xbox Arcade). I've added a hard drive, xbox live, and have thoroughly updated it. Maybe there's a specific video update I'm unaware of??

• 2 Server FC SAN Configuration

  - by BSte

  I have 2 identical servers: -48GB Ram -8GigE NIC's -2FC NIC's -2x72GB RAID1 Hard Drives -Server 2008R2 Host I also Have a Fibre Channel SAN: -16x146GB RAID10 Hard Drives -2xDual-port FC Controllers (Controller A and B both have ports 1 and 2) -Server 1 has Fiber to Ports A1 and B1 -Server 2 has Fiber to Ports A2 and B2 -I kept the default config with 1 Virtual Disk and 1 Volume -The default mappings show ports A1,A2,B1,B2 on LUN 0 with read-write My goal is: -2xVM's with IIS and Guest Level Failover -2xVM's with SQL 2008 Enterprise using a Single DB and Guest Level Failover -1xVM that is an application server, preferable with Host Failover. From what I read, this will also need AD for clustering to work. -I need at least 1 VM always running for IIS and the SQLDB. This includes hardware failover and application (ie: reboot a VM for Critical updates) I was told I could install the VM's and run them from the SAN, and this is what I've tried: Installed MPIO and HyperV on Server1 and Server 2 Added the SAN as Disk E: on both servers, made it GPT and formatted NTFS Configured HyperV on both server to store use E:\VD and E:\VHD On server1, I was able to install 3 VM's on the SAN and all worked well. On server2, I would start installing the other 2 VM's, but always at some point the VM's would get a corrupt .VHD message (either server). Everything I found about the message typically related to antivirus, so I removed all antivirus on both Host servers (now only running 2008R2). I reformatted drive E: (SAN), recreated the VHD and VD directories, installed 3 VM's on Server 1, and then had the same issue when installing VM's on Server2. Obviously something is wrong, but I'm not certain what exactly. My questions: 1) Are my goals possible with this hardware setup? -I've read 2008R2 supports FC SAN's, but a lot of articles seem to only give examples with iSCSCI setups 2) What would be the suggested route on setting up the SAN (disks,volumes,LUN's)? I've worked with HyperV on a single machine before and never had issues. Actual experience working on SAN's and clustering is new to me. Any suggestions or recommendations to get me in the right direction would be much appreciated.

• Format CD-rom on Windows 7 that Windows 95 can read

  - by Joe Majsterski

  I pulled out my ancient Pentium 100Mhz running Windows 95 to play a game from 1996. This game has a critical bug in it that requires a patch. The problem is, the computer has no way to connect to the Internet or to the LAN. I tried burning a CD-rom on my Windows 7 PC to run on the Win95 PC, but it doesn't even recognize that there's a disc in the drive. I did some research, and apparently Windows 95 can't read UDF format. All the solutions recommend, of course, downloading a driver or fix or somesuch, which is my entire problem in the first place. I tried formatting the CD-rom on my Win7 PC, but all the format choices are versions of UDF. Is there a way to get Windows 7 to format in way that is compatible with Windows 95? EDIT: I think the problem may be that I only have CD-RWs. I think a regular CD-R might work, but I can't find any in the house. I'll see if I can scrounge one up and try that.

Now problem is i tried both Ubuntu and Mandriva with no resolve the issue is the onboard drive detects and actually SHOWS that it's there but no wireless networks detect so it's saying no SSID's are broadcasting which i know is a lie since I'm running a 2wire bell dsl modem with built in wifi and a Linksys wrt54g w/ DD-WRT firmware and both are broadcasting fine. Why don't i use the USB? In the hardware device manager in mandriva it shows up as unknown but shows that it's realtek and that it's a 8192 chipset. but no option to for a driver install and when i do a make in terminal i get this error and no clue what it means [root@John-PC rtl8192se_linux_2.6.0010.1020.2009_64bit]# make make: *** /lib/modules/2.6.31.12-desktop-3mnb/build: No such file or directory.

• Poor NFS Performance: OpenFiler

  - by Safin09

  Good Day Everyone, I have an issue with OpenFiler, a Linux-based operating that converts a computer system into a SAN/NAS appliance. Here is the problem. In my environment we have two Netapp Storevault 500 appliances that I normally perform backups to a NFS share. There are two backup cronjobs that use ghettoVCB to backup two groups of VM's. One group is a pool of 3 VMs. This takes 13 mins to complete. A second job that backups a pool of 5 VMs to a 2nd Storevault appliance which takes 2 hours. We then installed Openfiler on a old server that has 2 core Xeon processors. There is a software RAID 5 process in place. When performing the same backups to a NFS Openfiler share, the first backup job, which takes 13 mins, takes around 4 hours. The second backup job, which takes 2 hours, takes almost 10 hours to complete. This is unacceptable!!!! Especially considering the strain placed on the host ESX Server. I assumed that because of the software RAID 5, the overhead on the CPU explained the long backup times. I then installed Openfiler on a 2nd server, an IBM x306 machine which has a P4 Intel processor. This time no software RAID or any RAID at all. A single 750GB hard drive that contained the OS and the rest of the disk uses to backup VMs to a NFS share. I performed the first backup job of the pool of 3 VMs. This time the backup job took 1 and 1/2 hours to complete instead of 13 mins!!!!!!!!!! Is Openfiler simply poor at being an NFS Server!!!!!!!!!!!!! Has anyone else had these issues with Openfiler?

• Htpc aka "Media Center": cheap and *silent*?

  - by Unknown

  It may be me, or the place I live (Italy), but it seems pretty hard to get a build or a prebuilt nettop or a laptop that fits the need. I need something silent able to playback all h.264 fullhd content without stuttering, and well (and not loosing the hw acceleration because of softsubs...) silent not ugly silent and (possibly) cheap. I'm going the linux route, therefore i'm moving towards a cpu-based or nvida-integrated solution (i don't think ati hw accelerated playback - or the intel "hd" acceleration - is useable yet). Ion nettop; it's either the Acer Revo (but here it's incredibly pricey and it's hard to find the dualcore version) or the Asrock Ion 330, that in the current version is rated "silent" at 26Db. 26. Sounds pretty noisy to me!!! the previous version was even worse. was this product really aimed at htpc market?? the Dell Zino - i think it's ATI based unfortunately. Laptop: correct me if I'm wrong: sub 600€/$ units are quite loud under full load (because of the tiny fans). ULW laptops are indeed quite similar: tiniest fans = high pitched noise and the cpu still lacks power for non hd-accelerated video decoding Handmade build: little money can be saved with underpowered cpus, a low-midrange cpu would help in the case of non-hw-accelerated content the cases are quite pricey the PSU one has to get ranges between 100/150 €/$ minimum to keep the noise down a low-mid build, all included, sums up to over 650 €/$ for a still-looking-ugly-unit, without the blu-ray drive. Please help. What do you advise on this? ;) Am I ignoring laptops too much, maybe? Are low-priced Acers that noisy/high pitched under full load?

• Can't get an IBM xSeries 345 server to load Windows Server 2003 using ServerGuide utility

  - by Kyle Noland

  I have a client that has an IBM xSeries 345 eServer. Per the IBM support website, I have downloaded the ServerGuide Setup 7.4.17 installation ISO and burned a bootable CD. The CD boots fine and loads the utility. I walk through the following screens without any issue: Set the date and Time Detect the IBM ServeRAID card and install the latest firmware Clear the hard disks Set up the RAID array The next step is format the NOS partition. I select my partition size and the utility goes through the following steps: Creating NOS partition Formatting NOS partition (NTFS) Copying W32 files The copying W32 files takes about 10 minutes. I see the CD drive and disks working hard. When the copying is complete, I'm taken to a blank page just NOS Partitioning at the top. At the bottom of the screen are the familiar Back and Exit buttons. I see the place where the Next button should be, and if I click on it I can tell there is something there, but the space is empty. No button is displayed and clicking the empty spot doesn't ever take me to the next screen. I can't load the OS until I get past this part. I have already tried: Burning multiple copies and versions of the ServerGuide CD Letting the final screen just sit there over the weekend thinking it might advance after syncing the drives or something Has anybody else seen this? I'm really at a loss here. EDIT: I found another person who has the exact same problem as me: http://www.ibm.com/developerworks/forums/thread.jspa?messageID=14451763

• Mystery undeletable file

  - by Hugh Allen

  I can't delete C:\Config.Msi\75ce84f.rbf. it's not readonly, system or hidden it's not in use by another process (according to Process Explorer) the NT security permissions aren't the problem either - I am the owner and have Full Control ; as a double-check, the Effective Permissions tab shows that I have permission to delete. Yet trying to delete the file gives "Access is Denied" from both Explorer and cmd. I can however rename it or move it to another folder on the same drive. I can also read it and Virustotal says it's clean which is what I would expect (it's just a Windows Installer temp file - a copy of some DLL I think). The relevant line from Process Monitor is: 6:52:14.3726983 PM 112 Explorer.EXE SetDispositionInformationFile C:\Config.Msi\75ce84f.rbf CANNOT DELETE Delete: True Write 1232 Background: I'm using XP SP2. I recently repaired my Adobe Reader installation to make it the default browser plugin again instead of Foxit. (there seems to be no UI to do it otherwise?) So the installer did its thing and then asked to reboot. As is my habit when rebooting is inconvenient I declined the offer and ran pendmoves to find out what files the installer had scheduled to move / delete. It wanted to delete two files with .rbf extension (rollback files) located in C:\Config.msi\. (this applies to both even though I've been speaking about one). So I tried to delete them manually and couldn't. Does anyone have any ideas what could be preventing deletion? (and I don't think it's malware even though I'm not running AV at the moment)

• Disabling CPU management

  - by Tiffany Walker

  If I add the following processor.max_cstate=0 to the kernel command line for boot up, does that disable all CPU power management and throttling? I also found: http://www.experts-exchange.com/OS/Linux/Administration/A_3492-Avoiding-CPU-speed-scaling-in-modern-Linux-distributions-Running-CPU-at-full-speed-Tips.html The link talks of Change CPU governor from 'ondemand' to 'performance' for all CPUs/cores and disabling kondemand from kernel.

• problem booting crusty old windows XP

  - by Carson Myers

  I have an acer aspire laptop running Windows XP home. I believe I have some virus on it, I'm not sure--I mostly just run linux in a VM on it so I wasn't too worried. I'm not sure if that virus caused this problem. The laptop wasn't recognizing my USB hard drive for some reason so I decided to restart it. When it started up, it got past the memory test, past the boot screen, (but it paused right here on a blank screen for awhile) and flashed the desktop once (like it does just before the login screen) and then crashed. I got a quick BSOD and then it restarted. Then it tried to boot again, etc etc infinite loop of failure. Well, before trying safe mode, I disabled automatic restart on system crash so I could read the blue screen. There wasn't anything important on it, it said *** STOP: 0x00000000 (0xC0000000 0x,.... ) beginning physical memory dump physical memory dump complete That's not verbatim (obviously) but it didn't help me. so I booted in safe mode, and it stopped on the driver gagp30kx.sys and then restarted (and infinite loop of failure again). I burned a recovery CD and tried that. It loaded it, and I went into repair mode. I ran chkdsk and then disabled the AGP driver. Same thing on booting in safe mode except it stopped at mup.sys instead. I enabled the AGP driver again, and ran chkdsk again from the CD. It said it found problems but didn't say it fixed them. So I ran it a second time, and it said "performing additional checking or recovery" lots of times (I can't tell how many, they went above the screen top). I tried booting again and no luck. Every time I run chkdsk after trying to boot again it says it found and fixed more errors. I think it might be whatever driver is after the AGP driver, but I don't know what it is or how to find out. Can anyone help me fix this?

• WebDAV through Apache2 permissions/missing files

  - by Strifariz

  I have a WebDAV setup on Apache2 on a server running Debian 5.0 (Lenny), which I am accessing through a mapped network drive under Windows 7. The setup appears to run fine, I receive no permission errors when copying a file to the share the first time, but the file never shows up in the directory (it's invisible, doing a ls -lha on the directory as root on the server also shows no files. When attempting to copy the file once more I am informed that the file already exists though, and I am asked if I wish to overwrite the file, when selecting "Yes" to this, I receive a permission error saying I'm not able to write to the folder. My logs aren't reporting any access violations of any kind, what could be the problem?

• BSOD trying to migrate Windows XP from a physical to a virtual machine

  - by pauldoo

  I am attempting to migrate a Windows XP Home installation from a physical machine to a virtual machine. The physical machine has two hard disks; the first is 250GB containing the "C:", the second is 1TB containing "D:". I'd like to create a new virtual machine stored on the D:, which is a copy of the Windows XP Home installation that is currently on the C:. (This will leave the 250GB drive clear for me to install a fresh copy of Windows 7, and still be able to access the old XP installation if necessary.) The first method I tried was to follow the instructions here: http://www.virtualbox.org/wiki/Migrate_Windows I booted up from an Ubuntu Live CD in order to execute the Linux commands whilst the Windows system wasn't running. With this method the virtual machine would always blue screen on startup with a "STOP 0x0000007B" message. The instructions above say to try a "repair install" using the Windows XP disc. Unfortunately for me my XP disc is scratched and will not boot so I was unable to try a repair install. The second method I tried was to use "VMWare Converter Standalone Client". This tool executed without any errors, but again produced a virtual machine that blue screens on startup with the same "STOP" message. Are there any other methods to move the Windows XP installation into a virtual machine? I think next I will try some more manual process to create the cloned virtual machine. I think I will try installing a fresh copy of Windows XP to a virtual machine, then once that is booting OK I will ntfsclone the source C: partition over the top. Perhaps this will fix the booting problems if the issue is related to the MBR or partition table in some way.

• Windows Vista will not boot; the file header checksum does not match the computed checksum

  - by Magnus

  Right out of the blue, my wife's Sony Vaio stopped booting. This, not so fun, error message displays immediately after POST: The system cannot boot. The file is possibly corrupt. The file header checksum does not match the computed checksum The repair option on the Vista DVD says everything is fine and dandy, it couldn't be more happier or more clueless... Any ideas? Update: CHKDSK reports no issues. CHKDSK /r reports no issues. (Heck, both Windows Repair and CHKDSK could just as well tell me that I have won on lottery or that the earth is flat... ) Some have reported that a mem diagnostic could help, but for me the mem diag has just ran through 5 passes. It doesn't seem to help. According to Sony, pressing F10 should bring up the restore menu, but it doesn't, the error pops up straight after Bios POST. It seems that this error is first in line of all options at this point, and is doesn't put a smile on my face. I have attached an external USB drive and copied all user data/documents to it. I feel an OS re-install is around the corner.
