• DVD ROM is not working

  - by Cyril N.

  (note: I don't know in which StackExchange site to put this question, I'll thank the moderator that will move it to a more appropriate place, if there is a S.E. available for my question). I have a DVD RW drive that is well listed in the bios, and if no CD is in, it is also present in the "My Computer" of my Fedora 16. But when I put a disc on it, the icon disapear from "My Computer", and I can not do anything with this ! (Like erasing a RW disc). I'd like to boot a Fedora 17 Live CD image. I burned it on an other computer but when I try to run it in bios, nothing is done and I'm redirected to Grub of my HD. The command cdrecord -scanbus shows this : wodim: Warning: controller returns wrong size for CD capabilities page. wodim: Cannot get CD capabilities data. 6,1,0 601) 'HD-DT%ST' 'DVD%RAM G@22NP20' '1&04' Removable CD-ROM And when I try to mount manually the disc, I got this error : mount: block device /dev/sr0 is write-protected, mounting read-only mount: /dev/sr0: can't read superblock Here's a paste of dmesg | grep sr0 : [ 5.161265] sr0: scsi-1 drive [ 5.161621] sr 6:0:1:0: Attached scsi CD-ROM sr0 [ 834.545978] sr0: Hmm, seems the drive doesn't support multisession CD's [ 841.731194] sr0: CDROM (ioctl) error, command: Get configuration 46 00 00 00 00 00 00 00 20 00 [ 842.021640] sr 6:0:1:0: [sr0] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE [ 842.021652] sr 6:0:1:0: [sr0] Sense Key : Aborted Command [current] [ 842.021662] sr 6:0:1:0: [sr0] Add.

I then changed the IDE cable, but still no success. What can I do to make it work? Thanks for your help.

• How to check for duplicate files?

  - by miorel

  I have an external hard drive on which I have backed up files several times. Some files were modified between backups, others were not. Some may have been renamed. Now I'm running out of space, and I'd like to clean up duplicate files. My idea was to md5sum every file on the drive, then look for duplicates, and diff the relevant files (just in case, haha). Is this the best way to do this? What are some other methods of checking for duplicate files?

• Windows 7 - Move location of Eventlog

  - by Jörg B.

  I am having a particular nasty problem of my main system drive 'disappearing' all of the sudden while the system is running. The vendor somewhat knows about this but has not managed to fix it completely over multiple fw iterations. Problems I have with the support is that I cannot provide any particular system log files/entries to further analyse what might have been going on because, well - windows cannot write to its 'lost' drive before bsod'ing. Is there any way to configure where Windows 7 stores its event logs so that I could specify a second physical hdd?

• How can I restore my system from WIM files?

  - by Brian Henk

  I installed another OS on my netbook and decided I want to revert back to Windows 7 Starter. I was careful to keep the recovery partition, but even when I manage to boot to it, the system just restarts a few seconds after selecting "restore." I grabbed all the files from the recovery partition onto a flash drive. I also have been able to use this drive to boot a Windows 7 install, but it was unable to find the recovery partition. These WIM files seem to be the key to installing Windows again. How can I use them?

• Windows 7 installation asks for DVD drivers

  - by koen

  I have installed Windows XP on my machine (Company CQ5020NL). Before I was able to do that, I set the SATA controller to IDE in the bios. Now I want to install Windows 7 upgrade. The DVD boots into the installation setup, but when I click "Install now" and am asked to load "A required CD/DVD drive device". When I click "Browse" I can browse the installation dvd and the drive I want to install to. I have tried all the SATA options in the bios already. I have no idea what to do... can anybody help me out?

• Proper Imaging Procedures to Restore and Deploy Image with Separate System Reserved Partition

  - by alharaka

  UPDATE: As per my experience here, no one responded. If I do not hear back from TechNet forum members about it, I will post a bounty here, if it makes a difference. I have banged my head against a wall for what seems like all week. I am going to explain my simple procedure, and how none of it, absolutely none, seems to work afterword despite few alternatives and everyone on the internet telling assuming this is how to do it. Diskpart Commands to Create FS Structure REM Select the disk targeted for deployment. REM REM NOTE: Usually disk 0, but drive failure can make it external USB REM media. This will erase the drive regardless! select disk 0 REM Remove previous formatting. clean REM Create System Reserved partition bootloader and files. create partition primary size=100 REM Format the volume format fs=ntfs label="System Reserved" quick override noerr REM Assign the System Reserved partition the D: mount for now assign letter=C REM The main system partition, size not specified to occupy whole drive. create partition primary REM Format the volume format fs=ntfs quick override noerr REM Assign the OS partition the D: mount for now assign letter=D REM Make this the active/bootable partition. sel disk 0 sel partition 1 active REM Close out the diskpart session. exit Now, I thought this was madness, but it turns out the System Reserved partition and standard "System Partition" (C:, commonly both the boot and system volumes where you find the Windows directory AND the bootmgr/ntldr hardware files, this is where Windows 7 diverges) as mounted in the Windows PE session where I run these commands do not matter. See reference here. Since this needs to be BitLocker-ready, enter this crappy System Reserved partition that is separate 100MB of awesome that goes before the regular boot volume. I do this, then I proceed to the next step. Deploy System Reserved and Normal System Images REM C is still the "System Reserved Partition", and the image is just like it sounds. imagex /apply G:\images\systemreserved.wim 1 C: REM D is now what will be the C: system partition on reboot, supposedly. imagex /apply G:\images\testimage.wim 1 D: Reboot the system Now, the images I just captured should look good. This is not even sysprepped, but reapplying the same fscking image I prepared on the same reference workstation hours before. Problem is I get 0xc000000e could not detect the accessible boot device \Windows\system32\winload.exe or different kinds of nonsense revolving around being able to find the boot volume with all the right files. I try different variations of things, now none of them work. I tried repairs with bcdboot, with a fresh System Reserved partition or not, bootrec, and maually editing the damn BCD store with bcdedit. I tried finalizing the above process with and without bootsect /nt60 C: /force. I need to wrap up and automate this procedure. What am I doing wrong that does not make the image happy, but really just miserable.

• Folder Size Column on Explorer on Windows Vista/Seven

  - by Click Ok

  I'm a big fan of FolderSize, but unfortunately it works only on Windows XP. Even reading this and this, I'm not convinced that I cannot to have a column showing the folder size on Windows Explorer. Even with all "problems" FolderSize worked like a charm in WindowsXP. In a sysadmin life, FolderSize is explendid. Before select a lot of folders to send to backup in DVDs, I can check directly in Windows Explorer the size of the folders and get a set of folders with 4.3Gb to burn in a DVD. In another situation, I can view in the root folder the size of the bigger folders in the hard drive and start a good strategy of backup/partitioning/transfer to another drive/etc. If desired, I can tell a lot of another needs that in my sysadmin life I need a tool like FolderSize... There is someone that is actively developing a solution to show folder size on Windows Explorer in Vista/Seven Windows? What the problems that I can face if I develop myself that "add-in" for Windows Explorer?

• rsync creating thousands of ..ds_store files from mounted volume

  - by daniel Crabbe

  I've been using rsync on OS X to sync all our website admins. It was working fine until the OS X 10.6.3 update! Now it creates thousands of empty (0-kb) folders. It only does it when synching to a mounted network drive (which we need to do) as when I sync to my local drive it works as usual! I've tried excludes which don't seem to be working... also tried a different version of rsync so it's an OS X issue. echo "" echo "~*~*~*~*~*~*~*~*~*~*~*~*~*" echo " SYNCING up KINEMASTIK" echo "~*~*~*~*~*~*~*~*~*~*~*~*~*" /usr/local/bin/rsync -aNHAXv --progress --exclude-from 'exclude.txt' /Volumes/Groups/Projects/483_Modern_Activity_Website/web/youradmin/ /Users/dan/Dropbox/documents/WORK/kinemastik/WEBSITE/youradmin/ echo "" echo "~*~*~*~*~*~*~*~*~*~*~*~*~*" echo " SYNCING up CHRIS BROOKS YOURADMIN" echo "~*~*~*~*~*~*~*~*~*~*~*~*~*" /usr/local/bin/rsync -aNHAXv --progress --exclude-from 'exclude.txt' /Volumes/Groups/Projects/483_Modern_Activity_Website/web/youradmin/ /Volumes/Groups/Projects/516_ChrisBrooks/website/youradmin/ Has anyone experienced the same problem?

• Is it possible to mount a TrueCrypt volume to a NTFS mount point?

  - by Anthony

  The question is simple really. Under Linux etc.. you can mount TrueCrypt volumes, files or partitions, to any mount point of your choosing whereas in Windows the interface only shows drive letters. I'm wondering if I can mount the volume, a partition in this case, un-encrypted to a NTFS mount point, or folder, instead of using drive letters. The reason I ask is I am running out of letters :(. I'm using Server 2008 with the latest TrueCrypt install. Note: I know how to mount a volume directly to an NTFS folder mount point but doing so, and navigating to the mount point, prompts a notice saying the volume is not formatted - to be expected as the volume is not un-encrypted at this stage.

• Did Acronis True Image Home 2012 clone operation "lock" my BitLocker disk?

  - by Thomas Eyde

  After trying to clone my primary drive, which requires a reboot to proceed, BitLocker detected that the boot sector had changed and required the recovery keys. Not a good situation to be in on Sunday evening when it is your IT-department who hold the keys. After talking with the guys at IT, I have tree suspects on why BitLocker locked me out: The newly added, second hard drive in my machine. The changed boot-order in BIOS. The changes True Image did in order to do its things on boot. As an end-user, I should never have to end up in situations like these without any warning. I would like to know what really happened, so I can inform Acronis on how they can improve their product to avoid this situation in the future.

• is it worth defragging an iPod

  - by alimack

  Essentially my 5G iPod was cutting tracks off and generally misbehaving. So I did the following: 1) Use Diskwarrior - heavy directory fragmentation which it fixed; 2) Use iDefrag - some fragmentation but it kept halting as it couldn't move files; 3) Try to write out drive with Disk Utility - got a warning from DU so gave up before I started; 4) Completely restored using iTunes; 5) Reran Diskwarrior - still heavy directory fragmentation; 6) Reran iDefrag, still fragmentation although limited to two bands; The iPod is much quicker to traverse menus and no more track skipping. My question is this - is defragging worth it or does the heat generated by the process kill the drive and make it a self-defeating process. Anyone have any metrics/ figures? Clearly it's a bad idea for solid state drives like the nano & touch.

• RSync to WebDAV mounted volume very slow

  - by AlexC

  I have a mounted WebDAV store, which I am playing around with to try and put together my own pseudo-DropBox set up. However, it seems very slow to upload larger files (my bandwidth graph goes ok for a little bit, then just stops dead for long periods of time). Has anyone tried this? I'm wondering if the way it gets mounted makes rsync think it's a local drive or something and so may be chattier than it would be if it knew it was a mounted network drive? (I'm new to rsync so may be all wrong here!) I'm syncing using rsync -rv /source/directory/ /mounted/webdav/directory/ This is running using MacOS 10.6, and WebDAV is mounted using the native mounting mechanism.

• Apple RAID configuration vs Hardware RAID

  - by James Hill

  I am researching external HDD's capable or RAID 1 to store a large amount of video content during overseas filming. After filming, the content will be brought back to the office and offloaded onto our storage server. After doing some research, I've found that I can buy an external drive with a built in RAID controller, or I can buy an external drive, with 2 HDD's, that I can configure in a RAID 1 array using the OS. RAID 1 is what we're looking for. I've done some reading on software RAID vs. hardware RAID, but the resources I've found don't discuss performance as it relates to video content or what happens to a software RAID when the computer dies. Question 1: Will the hardware RAID be more performant when dealing with large video files? Question 2: If the mac dies, does my RAID die with it (will my data be accessible on another mac)?

• unable to access shared drives n win7

  - by colin

  OK, this is doing my head in. Not your usual Win7 sharing problem. Just built a win 7 comp to go onto my home lan and be accessed by all on the network, mostly running XP SP3. Installed it as a single HD+DVD system, got it happy, then added my storage drives, set them up in the right order and letters, rebooted, and shared them. Couldn't access the computer at all from any XP machine. Set the pasword thingy in win7 to NO, and now I can "see" all four shared drives from any machine, but can access only two of them. Please tell me whats going on as I've done nothing different from one drive to the other, just installed and set up drive letters as normal, then shared the damn things. The odd thing about it? the two 1.5T drives that have a lot of data on board are accessable, the two nearly empty 500G ones are not. ANY ideas? Cheers, Colin

• Computer Studdering When Transferring Over Network

  - by Nalandial

  This is a really weird problem that I've never even seen before. When I copy to or from my server share, my computer studders terribly and the data transfers very slowly at only around 12MB/s. By studdering I mean the mouse skips around and all my applications respond very slowly; as soon as I cancel the transfer it resolves immediately. I looked at Task Manager and the CPU is only at ~35% with plenty of RAM free. This only started semi-recently; before, I had no problems and the transfer speed maxed out the gigabit connection. I have two hard drives in my computer. When I try transferring files between drives it's fine, but when I copy from the share to either drive or to it from either drive, I get studdering. I'm running Windows 7 x64. Anyone have any idea what's going on? Any help would be much appreciated.

• Sharing external storage between different operating systems?

  - by CT

  I just received a Lacie 1TB external usb/firewire/esata drive. I have 2 machines. A macbook running osx 10.6 and a desktop running windows 7. I would like to rip my dvd collection to iso and store on my external. Right now I use my macbook's disk utility to rip dvds to iso. However my desktop is what is connected to my hdtv. I mainly just use the desktop for media. I'd like to format the external with a 200 GB partition for time machine backups and have the rest for storage. DVD iso are often above 8GB so that sort of eliminates FAT file systems correct? Do I have any options to be able to have my mac and pc both see the drive?

• Expectations for NTFS file recovery

  - by Fred Hamilton

  Yesterday I booted my XP system, and as I looked up a minute later I saw the light blue screen and tail-end of that pre-boot diskcheck Windows sometimes does if it finds an error (or was previously told to run a diskcheck drung the next boot). I didn't worry about it at the moment... But then I looked at my "scratch" disk, which was a 70% full, 750GB hard disk...and it now looks like it has been freshly formatted. It doesn't have a single file on it, just the hidden "System Volume Information" file and 750GB of freedom from data. I looked at some of the recovery tools from the Free NTFS partition recovery question and decided to try PC INSPECTOR™ File Recovery 4.x initially. It ran overnight and afterwards returned a list of thousands of files it could recover. The odd thing was that the filenames were lost, but the file extensions were not (WTF?). And all of the files were exactly 1,472kB in size. I recovered a dozen PDFs as a test, and 80% of them displayed OK despite being padded out to 1.5MB (though I assume any files 1472kB are hosed). My primary question is: Is this the best I can expect from any file recovery software when trying to recover NTFS files? Or is there perhaps something better out there? I assume this is as good as it gets, but wanted to check in with the experts first. Bonus questions: What might have happened to my drive? I didn't intentionally format it. I've never seen a disk error cause the drive to suddenly become a clean, reformatted drive. Could some malicious/confused software have told my PC to format my disk on reboot? Is that even a function Windows XP has? Why can the file extensions be recovered but not the filename? Does NTFS really treat them as separate entities? I thought I had 8.3 naming turned off, but maybe that had something to do with it. Or maybe it looks at the data in the file and guesses the extension?

• Removing RAID on a DELL power-edge server

  - by Simon Callan

  We have a Dell Power-edge T110 server, with either a PERC S100 or S300 raid controller (I suspect S100), and 2 x 500GB SATA hard discs. These discs are running in RAID-1 configuration, (either 1 or 2 virtual discs), and on top of this, we have the C and D drives. As we are running low on disc space, we are looking at dropping the RAID to get some disc space back. Is it possible to split the discs back into 2 seperate hards discs that the OS can see, without losing all the data on the drives? Even better, would it be possible to split the D: drive, leaving the OS C: drive in RAID1 configuration?

• Can I mark a folder as mountpoint-only?

  - by Collin

  I have a folder ~/nas which I usually use sshfs to mount a network drive on. Today, I didn't realize the share hadn't been mounted yet, and copied some data into it. It took me a bit to realize that I'd just copied data into my own local drive rather than the network share. Is there some way to mark in the system that this folder is supposed to be a mount point, and to not let anyone copy data into it? I tried the permissions solution here: How to only allow a program to write to a directory if it is mounted?, but if I don't have write access I also can't mount anything to it.

• How to copy files between windows 7 professional and enterprise machines?

  - by WilliamKF

  I've got a desktop system running Windows 7 Professional and a laptop running windows 7 Enterprise in a domain-joined computer and I need to copy around 50 GB of files from the Enterprise machine to the professional one. I'd rather not burn a bunch of DVDs or use my tiny flash drive of 1 GB to do the transfer. How can I mount a drive from one of the computers to the other so that I can just drag and drop? I tried using a homegroup, but the windows 7 Enterprise laptop does not see it from the professional desktop and the laptop cannot make its own homegroup since it belongs to a domain.

• Create 8.3 name for an existing directory

  - by Chris Karcher

  I have a machine that initially had 8.3 filename creation disabled. However, this was causing issues with some legacy software, so it was re-enabled. I'm wondering if it's possible to go back and "add" 8.3 filenames to certain existing directories. For example, say I have a directory named "C:\name with spaces" and I get the following output when I run "dir /x": C:\>dir /x Volume in drive C has no label. Volume Serial Number is 6873-65B8 Directory of C:\ 04/09/2010 01:57 PM <DIR> name with spaces ... I'd like to somehow add an 8.3 name for the directory without recreating it, and then get the following: C:\>dir /x Volume in drive C has no label. Volume Serial Number is 6873-65B8 Directory of C:\ 04/09/2010 01:57 PM <DIR> NAMEWI~1 name with spaces ... I tried the 'rename' command but it didn't do the trick.

• Annoying Search Behavior - Search Companion

  - by David Stein

  I'm running Windows XP Professional, and ever since the last service pack I've had a searching problem. When I want to search a network drive, I get the following message: This folder is not indexed. To search this directory plase use Search Companion or add this directory to your index via options. Basically, I have two questions. Is there some way that I can use the indexed search where appropriate and then have it switch over to the Search Companion automatically? Second, how does a programmer look at this code and think this is a good idea? I realize that this question is rhetorical. However, I must enter my search string into one search, receive the error, and then click "Search Companion" to bring up the new search window. This window doesn't even take the defaults from the previous one so I have to specify the search string and drive again.

• Any "Magic Tricks" For Getting Data Back After Windows 7 Install

  - by user163757

  My old man installed Windows 7 without making a proper backup, and now realizes he left behind some important data. He did a true "clean install", so there is no Windows.old folder in the root directory. However, I believe the format performed on the hard drive was only a quick format, so I am hoping there is some chance at data recovery. I took his hard drive out, and have spent a majority of the weekend researching data recovery options. I paid $70 for the GetDataBack software, but have had little success with it. I can see all of the files I want to restore, however they appear corrupt when I try to open them. With that all being said, does anyone know of a viable way to recover some of this data, or is it a lost cause all together?

• Clonezilla multiple disks restore to single disk

  - by Farseeker

  I have a clonezilla image from a machine that had 3 seperate disks (one partition per disk). I want to know if I can restore that image to another computer that has a hard drive that's much larger than the original, but only has one drive. Clonezilla is stating that it can't do this automatically, and perhaps I should try cnvt-ocs-dev but I've no idea what that means (Google is less than forthcoming with information about it too). Ok so I found out what cnvt-ocs-dev is, and that allows me to move source/destination targets between physical disks, but it doesn't seem to be able to move the partition as well.
