• How to back up a network volume to my Time Capsule?

  - by Mike

  I have a Time Capsule that I'm using for my backups. I have a network volume (coincidentally on the same time capsule) that I'd like to back up as well. How can I tell Time Machine to back up network volumes in addition to my main laptop hard drive? PS: yes, I know this setup isn't ideal. It'll incur 2x network overhead when backing up the network volume, plus my data won't be safe in the event of a drive failure since both copies will be on the same disk. However, it will give me some small amount of safety in the event I accidentally delete files on the network volume, among other things.

• Security of BitLocker with no PIN from WinPE?

  - by Scott Bussinger

  Say you have a computer with the system drive encrypted by BitLocker and you're not using a PIN so the computer will boot up unattended. What happens if an attacker boots the system up into the Windows Preinstallation Environment? Will they have access to the encrypted drive? Does it change if you have a TPM vs. using only a USB startup key? What I'm trying to determine is whether the TPM / USB startup key is usable without booting from the original operating system. In other words, if you're using a USB startup key and the machine is rebooted normally then the data would still be protected unless an attacker was able to log in. But what if the hacker just boots the server into a Windows Preinstallation Environment with the USB startup key plugged in? Would they then have access to the data? Or would that require the recovery key? Ideally the recovery key would be required when booted like this, but I haven't seen this documented anywhere.

• Connect a ssd externally such that hdparm is fully supported

  - by student

  I am just trying some hdparm magic with my new ssd (samsung 840 pro). However I don't want to change my drive over and over so it would be great if I could connect it externally to my laptop. I have a cheap sata-usb Adapter, but I feel it doesn't support the ATA commands send by hdparm. So what's the best way to do this? Are there sata-usb Adapters which fully support the hdparm things? Would it be a good idea to buy a sata-esata adapter to get full control over the drive?

• Windows 7 can't copy file - Error 0x800700DF: The file size exceeds the limit allowed and cannot be saved

  - by JJGroover

  Any attempt to copy files larger than about 40 MB from a network share (a SAN running open filer / Samba) to my local machine running Windows 7 always results in the following error and the copy fails: Error 0x800700DF: The file size exceeds the limit allowed and cannot be saved. I've tried copying to my C: drive and a USB drive with the same results. Smaller files copy just fine. Clearly 40 MB is not that big of a file so I'm assuming it is some buggy interaction between windows 7 and Samba perhaps. Google has so far turned up nothing. Can anyone point me in the right direction?

• Automating Disk Cleanup on Windows using commandline

  - by Ram

  I asked this question on the MSDN forums but there was no response. Maybe someone might be able to help me out here. I am trying to run Disk Cleanup in the command prompt (and through a C# program) and so I went through all the available options from this link: http://support.microsoft.com/kb/315246 While I am just trying to understand what I can do, it would be good if someone could explain why the drive option /d cannot be set while specifying /sagerun:n Or is it possible, by some way, to run /sagerun for a specific drive? Thanks.

• How to view status of software RAID 1 resynching?

  - by tputkonen

  I have two 500 GB disks and yesterday I mirrored first drive to the second one using software RAID 1. PC has now been on for 30 hours. Both disks say "Resynching", but there is no progress indicator. In addition, there is a small yellow exclamation mark on both disks. My questions are: How long could the synch take for 500 GB drive with about 150 GB of data? PC has 4 GBs of RAM and AMD dual core 4000+ Is there a way to monitor status of the synching? How can I check what the exclamation mark means?

• 284 GiB of data, 217.4 GiB of space

  - by Malfist

  I want to reinstall my OS, but I don't have the hard drive space to backup any more (I have a RAID 1 array, so I haven't done it for a while). In my /home I have 284.8 GiB of data, and I have a spare 250 GB (or 217.4 GiB) hard drive that I've been using for backup. What type of compression algorithm (if any) is capable of this type of compression? I don't care about the time, I have a quad core though, so something that utilizes all 4 cores would be great. I have tried 7zip with no success. Ran on one core for two days and failed because of lack of space. Any ideas?

• How do I back up my Windows partition from an Ubuntu live CD?

  - by lalli

  My Windows partition (C:) is corrupt. I'm booting up from an Ubuntu live CD and trying to copy all the files from C: to my external drive, but the system expands all of the links, producing a projected copy size of 1.8TB (my external drive is just 1TB, and the data in c: is around 700MB). Then I looked at dd and other backup utilities. Anything I looked into, I couldn't figure out whether or not the image would be readable in Windows through any other app. Has anyone else tried to back up data from a corrupted Windows installation using Ubuntu?

• Software that supports ATA Secure Erase Command

  - by vy32

  We have a lot of drives that need to be sanitized. NIST SP 800-88 recommends software that uses the ATA Secure Erase command. That's apparently the only way to be sure that the drive is properly wiped, due to bad-block remapping and such. I know that this functionality is available in hdparm. The problem with that approach is that it is inconsistent on multiple platforms, occasionally times out, doesn't have error-checking logic, and doesn't check the resulting drive to make sure that it has, in fact, been erased. So a proper program might use hdparm, but hdparm by itself isn't an answer. I'm looking for open source software that implements ATA Secure Erase. Ideally it will be a bootable disk image like DBAN, but it will use the ATA command.

• Seasgate GoFlex NAS + Horrible Speed = Bad Experience

  - by Jon H

  I am having issues with transfer speeds from my desktop PC to my NAS. I have my NAS hooked up to a Gigabit Gateway as well as my Desktop with Cat 5e. I see up to 4.0 MB/Second Transfer Rates, the normal is about 2.5 MB/Seconds. There is 3 Partitions on my NAS, Public, Private, Backup. When I transfer from Private to Public I see the speeds above. If its under the same partition almost instant. I was wondering if the speeds I am seeing is in due to my Computer or the NAS. I was looking into building my own Media Server in due to these horrible speeds. Is their anything I can do in the mean time to speed this up? Motherboard = M3970AM-HP (Angelica) Processor = AMD FX 6100 Ram = 10GB PC3-10600 MB/sec Hard Drive (1) = 1.5TB SATA 3.0GB 5400RPM Hard Drive (2) = 120GB SATA SSD NAS = Seagate 3TB Go Flex Home Connection (1) = 1000 Base T Connection (2) = Wireless N

• What Commands Does Windows Startup Repair Run?

  - by user138284

  Background: I created a wim image that we are planning to deploy to some of our computers, but when I image a computer with it from a flash drive it continually reports that the BOOTMGR is missing (and no, it's not booting off the flash drive). I am able to resolve this by running Windows Startup Repair, but I would rather just add whatever command is resolving the issue to a script that runs after the image. I have already tried running fixmbr, fixboot, rebuildbcd, and nt60, but none of those resolve the issue. Basically, I would like to know what exactly is being done when I run Windows Startup Repair.

• MegaCli newly created disk doesn't appear under /dev/sdX

  - by Henry-Nicolas Tourneur

  After having successfully added 2 new disks in a new RAID virtual drive (background initialization done), I would have exepected it to appear under /dev/sdh but it's not there (so, unusable). The system is running a CentOS 5.2 64 bits, HAL and udev daemons are running, not records of any sdh apparition under the messsage log file or in dmesg, only MegaCli do see that virtual drive.

• Installing win xp media center 2005

  - by wdizz

  I have a Dell 710 XPS H2C running Vista Business, I wish to clean install Win XP media center 2005. I wiped my hard drive with Wipe Drive Pro and proceeded to install Win XP, the install starts and goes thru the various prompts but when it comes to 'installing windows' I get a blue screen that flashes briefly (to fast to get the error code) and then reboots. This happens with any XP system disk (iv'e tried 4), but it installs Vista, 7 or Linux with no problems. I contacted Dell Support who have yet to give me any solutions to resolve the problem. Is there anyone out there with any ideas please.

• Disk quota problem in Windows Server SBS 2003

  - by deddebme

  I have got a new job and the existing SBS 2003 domain setup is unsecure (i.e. everyone is a domain admin etc etc). There are lots of problem due to inexperienced "network admin", and I am trying to fix them one by one. There exist one issue which I found quite weird, that the "Quota" tab exists in the C:(NTFS) drive but not the D:(NTFS) drive. I played around with gpedit to enable disk quota (it was "not configured" before), but still I can't see that tab. Have you seen this problem before? How did you solve it?

• Allow WRITE access to local folders machine in 2003SBS AD

  - by Dan M.

  Have a SBS2003 client with a mess of a domain that is in process of being cleaned. But, for the life of me I cannot find a setting that will allow write access to the local hard disk for domain users with redirected profiles(to the server). This is needed only for one program that will not follow a symbolic link to the network path, instead it seems to be hard coded to the %appdata% folder but only on the c: drive.... So question is how can I allow "Domain users" write access to the local %appdata% directory? I have tried setting it manually on a machine but it kept resetting to RO no matter how many times I tried. Every time I would un-check the RO property it would reset sometime right after i hit OK. Thanks in advance! Dan

• "Verifying DMI Pool" hang caused by raid array..

  - by Ling

  Hi Experts, I have a problem, I obtained a new server with 4 hard drives (2 500 gig, 2 two TB), and an adeptec RAID card. I arranged them in two arrays with RAID 1 (500 gigs together as primary and the 2 TB drives for lots of data). When both arrays are configured, the server hangs while booting at message "Verifying DMI Pool", however if I remove the second array from the configuration the server boots fine. I have checked they are both on different channels, I have disabled all other peripherals from the boot menu and ensured the hard drive is #1. I have booted into the linux rescue mode and checked that it is reading both arrays fine. What else could be causing these problems? Thanks

• Full Backup & Restore for Windows Vista

  - by Thomas Matthews

  I'm looking for a freeware or low cost application that will backup everything, including registry on Windows Vista Home Premium and to restore from a CDROM disk. The destination is an external hard drive on USB 2.0. Searching on SuperUser and Stack Overflow show articles, but don't mention full backup of the registry and complete restore using CDROM. I would also like to have compressed output and incremental backups. One article mentions CloneZilla, but their web page says that the incremental feature is not supported. I am using Windows Vista Home Premium, Service Pack 1. I need to backup 200 GB onto a 230 GB drive and would like to have multiple backups (thus the need for compression). Other requirements: Single file restore Quality is more important than performance. Application must run on Windows Vista. Extra: Run as daemon or background task on 4 user system. Thanks

• Adding unallocated partition to Ubuntu in VMware

  - by AMS949

  I've installed Ubuntu 9.10 on a Windows XP using vmware. As most do, I initially setup the size of the virtual drive to 8GB and soon realized I need more. I used the VMware utility to expand the virtual drive and added another 4GB, which I can see using GParted. Now my dilemma is how can I "merge" the newly created space to my original? I need to add the unallocated space. I tried before and after formatting the new space but still whenever I try to resize/move /dev/sda1 it looks like it is using its maximum capacity. Also, GParted is being used from the GParted live CD not from the Linux live CD.

• How can I see logs in a server after a kernel panic hang?

  - by Low Kian Seong

  I am running a production gentoo Linux machine, and recently there was a situation where the server hung in my co-located premises and when I got there I noticed that the server was hung on what appeared to be a kernel panic hang. I rebooted the machine with a hard reboot and was disappointed to find out that I could not find a shred of evidence anywhere on why the machine hung. Is it true that when I do a hard reboot the messages itself will get lost or is there a setting I can do somewhere say in syslog-ng or maybe in sysctl to at least preserve the error log so that I can prevent such mishaps from happening in the future ? I am running a 2.6.x kernel by the way. Thanks in advance.

• SSD install - what do I need to watch out for when reconfiguring SATA ports?

  - by tim11g

  I installed a Samsung 840 SSD in a Windows 7 machine. It seems to be working fine, but I'm not seeing the expected performance. The AS SSD benchmark gives 76 for read and 138 for write. At the upper left of the benchmark it says "pciide - BAD" and "31K - BAD". I'm assuming the "pciide BAD" means the motherboard (Gigabyte GA-P35-DS4) is configured as IDE emulation and needs to change to native SATA. I don't know what the "31K" refers to. The bios settings look like this: I saw this article that indicates that changing the SATA mode of the boot drive can cause problems (Blue Screen): Error message occurs after you change the SATA mode of the boot drive What is the correct procedure to change the SATA Mode without causing a system failure? Apply the registry change from the MSFT article above first, then reboot and change the SATA mode? Will the SATA mode change in the BIOS affect other drives?

• Gparted: Copy Greyed Out

  - by David

  I booted my system to a gparted linux live CD and I have two partitions: /dev/sda1 /dev/sda2 I want to move both of them to my new physical hard drive (called /dev/sdb). When I right click on /dev/sda1, I can choose copy and then paste it onto /dev/sdb. When I right click on /dev/sda2, copy is greyed out and there is a yellow exclamation point to the left of the disk. I know that the disk works since I can boot my computer from it. Why won't gparted let me copy /dev/sda2 to my new hard disk? Since the option is greyed out, I don't even get an error message. Thanks!

• Does SQLIO lie when run from a Hyper-V guest on a VHD?

  - by ScottStonehouse

  SQLIO seems like a useful tool. I thought it would be interesting to try to measure the speed difference between a physical disk and a VHD. So I ran SQLIO on the Hyper-V host on the physical drive. Results seemed reasonable. Then I ran it from the guest to test the vhd (on the same physical disk). I expected it to be a bit slower. But instead it was way faster - like 0ms average latency. So I'm trying to learn something here. It seems like hyper-v is fooling SQLIO somehow but I don't understand it well enough to figure it out. It's a dynamic vhd, no snapshots or anything, and the vhd is the only file on the disk. The physical disk is actually a two SAS drive RAID 1.

• Ubuntu login takes 15 seconds, "I/O error dev fd0 sector 0"

  - by Dan

  After upgrading to Ubuntu 10.04, when I first login it takes 10+ seconds where it just sits at the gdm backgroup before taking me to gnome. By switching to a terminal window during this 10 seconds I saw the error message "I/O error /dev/fd0 sector 0" being outputted. I assume this has to do with the floppy drive... but I don't even have a floppy drive! How do I disable this device and make this error message go away (and hopefully fix the long wait)? Thanks.

• Darik's Boot And Nuke - ERROR /dev/sda

  - by user1403844

  I'm trying to wipe the drive of an old company computer with DBAN so I can install Redhat Enterprise and learn Linux (it's a Dell Inspiron 1210, if that matters). I burnt DBAN to a CD and boot from that CD (running on an external USB CD drive). Whenever I try to run the utility--whether it's Autonuke, or any of manual wiping methods-- it spits on the errors: ERROR /dev/sdb ERROR /dev/sda From what I've read on some other forums, there are some issues with other drives or removable media interfering however I've disabled all other drives in bios, leaving just CD/DVD and the Hard Disk but still no luck. Any advice on how I can reconcile these errors and wipe the disk?

• Recovering a Windows XP License key

  - by Fortyrunner

  I threw out a Windows XP machine a while ago (the motherboard failed). I kept the hard drive and the XP installation media. Problem is the license key was on a sticker on the machine - doh! The original manufacturer has gone bust (Evesham) and I suspect that Microsoft will be of little help. Is there any easy way to get the license key off the hard disk? Can I just find the file with the registry data in it and get the key using a hex editor? I really need a spare XP key for use in a Windows VM.
