  • Is there a clean way to tell Windows to release a volume?

    - by zneak
    Hey guys, I'm trying, under Windows 7, to run a virtual machine with VMWare Player from an OS installed on a physical partition. However, when I boot the virtual machine, VMWare Player says that it couldn't access the physical drive and has to abort there. This seems to be a generally acknowledged problem in the VMWare community, as Windows Vista introduced a compelling new security feature that makes it impossible to write to a raw drive without obtaining exclusive access to it. I have googled the issue and found a few workarounds. However, the clean ones seem to only work on whole physical disks, and not on partitions. So I would be left with the dirty solution. In short, it meddles with the MBR to erase any trace of the partitions to use, makes Windows forget about them, then restores the MBR so we can launch the VM. Is there a way to let VMWare acquire exclusive access to the partition without requiring me to nuke it away?

  • Vista stuck at "Shutting down..." screen. Any way to get verbose logging?

    - by CapBBeard
    Hi all, My home machine has been running fine for about 3 years, no problems at all. Within the last couple of weeks it's had real trouble trying to shut down. It'll get so far and then just sit there at the "Shutting down..." screen for hours. I've left it overnight, I've tried in safe mode, all to no avail. These days, I just wait for the disk activity to finish up and then hold the power button to turn it off. Feels dirty as, especially because there's a RAID involved! The hardware itself is in pretty good shape and of decent spec; Core 2 Quad, 4GB RAM, 1TB RAID 1+0, so it's not quite like a 7 year old PC coming to end of life! In the last month, hardware hasn't changed except for a new monitor. Admittedly I haven't tried unplugging the monitor but I've never heard of that preventing a shutdown. I might give it a whirl later I guess, as a last resort. I've uninstalled old apps, done updates, checked the event log, looked in device manager, uninstalled all non-present devices, disabled various non-critical devices (imaging, audio etc), unplugged peripherals, stopped non-essential services, unplugged the network, disabled the network adapter entirely, ran chkdsk, verified my RAID, the list goes on. But not a single lead. I'm pretty stumped. It could be hardware, but I have no other evidence to suggest so; when the PC is running, it runs fine. Temperatures are good, gaming is smooth as always, disk performance is fine. Event log even makes it look like the shutdown was completed (gets to the point where the event log service stops). In fact, the PC doesn't appear to realise that I cut the power to it. So my question is, does anyone know if there is a way I can get some verbose output (or a log) from shutdown to give me some idea of what is causing the issue? I'm guessing it's stuck unloading some app/driver but it would be good to get some specifics! Unless anyone has any other ideas? I suspect a reinstall would resolve the issue, however I'm looking to get a new PC built in the next month or so, and the reinstall is going to be quite a big job so I'd rather just wait until then if it comes to that. Would still be nice to get this sorted in the mean time though. Cheers!

  • Linux Software RAID1 Rebuild Completes, but after reboot, its degraded again

    - by zimmy6996
    I have been beating my head with an issue here, and I'm now turning to the internet for help. I have a system running Mandrake Linux, with the following configuration: /dev/hda - This is a IDE drive. Has some partitions on it that boot the system and make up most of the file system. /dev/sda - This is drive 1 of 2 for a software raid /dev/md0 /dev/sdb - This is drive 2 of 2 for a software raid /dev/md0 md0 gets mounted but fstab as /data-storage, so it is not critical to the systems ability to boot. We can comment it out of fstab, and the system works just fine either way. The problem is, we have a failed sdb drive. So I shut the box down, and have pulled the failed disk and installed a new disk. When the system boots up, /proc/mdstat shows only sda as part of the raid. I then run the various command to rebuild the RAID to /dev/sdb. Everything rebuilds correctly, and upon completion, you look at /proc/mdstat and it shows 2 drives sda1(0) and sdb1(1). Everything looks great. Then you reboot the box ... UGH!!! Once rebooted, sdb is missing again from the RAID. It is like the rebuild never happened. I can walk through the commands to rebuild it again, and it will work, but again, after reboot, the box seems to make sdb just vanish! The real odd thing is, if after reboot, I pull sda out of the box, and try to get the system to load with the rebuilt sdb drive in the system, and when I do, the system actually throws and error just after grub, and says something about drive error, and the system has to shut down. Thoughts??? I'm starting to wonder if grub has something to do with this mess. That the drive isn't being setup within grub to be visible at boot? This RAID array isn't necessary for the system to boot, but when the replacement drive is in there, without SDA it won't boot system, so it makes me believe there is something to that. On top of that, there just seems to be something wonky here the drive falling off of RAID after reboot. I've hit the point of pounding my head on the keyboard. Any help would be greatly appreciated!!!

  • iTunes can't see iPhone after reinstalling Leopard

    - by Joseph SG
    My Mac hard disk died, so I replaced it and installed OS X Leopard 10.5.8. Problem now, iTunes doesn't see my iPhone 3GS at all. iPhoto works just fine, but iTunes is blind. I have too much info on my iPhone, I don't wish to restore/reset it and wish to get everything from my iPhone sync'd into iTunes afresh. How can I do that?

  • Dell PowerEdge R720 - Corrupted RAID

    - by BT643
    Apologies in advance for the lengthy question. We have a Dell PowerEdge R720 server with: 2 x 136GB SAS drives in RAID 1 for the OS (Ubuntu Server 12.04) 6 x 3TB SATA drives in RAID 5 for data A few days ago we were getting errors when trying to access files on the large RAID 5 partition. We rebooted the server and got a message about the raid controller has found a foriegn config. We've had this before, and just needed to use Dell's RAID configuration utility to import foreign config on the RAID. Last time this worked, but this time, it started doing a disk check then we got this: FSCK has returned the following: "/dev/sdb1 inode 364738 has a bad extended attribute block 7 /dev/sdb1 unexpected inconsistency run fsck manually (i.e without -a or -p options) MOUNTALL fsck /ourdatapartition [1019] terminated with status 4 MOUNTALL filesystem has errors /ourdatapartition errors where found while checking the disk drive for /ourdatapartition Press F to fix errors, I to Ignore or M for Manual Recovery" We pressed F to try and fix the errors, but it eventually errored with: Inode 275841084, i_blocks is 167080, should be 0. Fix? yes Inode 275841141 has an invalid extend node (blk 2206761006, lblk 0) Clear? yes Inode 275841141, i_blocks is 227872, should be 0. Fix? yes Inode 275842303 has an invalid extend node (blk 2206760975, lblk 0) Clear? yes ....

We replaced the drive with a spare, and tried "F" to repair it again, but we keep just getting the same error as above. In the RAID configuration utility, all drives show as "online" and "optimal". We do have this data on another replicated server, so we're not worried about "recovering" anything, we just want to get the system back online asap. The server has 64 or 32GB memory, can't remember off the top of my head, but either way, with a 14TB RAID, I think it may still not be enough. Thanks EDIT - I checked the memory usage while fsck was running as suggested and after 2 or 3 minutes, it looked like this, using up nearly all of our servers memory: When it failed after 5 minutes or so with the error in my post, the memory immediately freed up again:

  • Shared storage solution for our sql server backups

    - by Gokhan
    We have 3 clustered sql servers. We have 5+ multi terrabyte databases and their backup files (compressed using quest litespeed) are hitting over 600gb each, We are required to keep at least a week or two weeks (if we can) of weekly full backups and then 6 days differential backups, and a week or 2 weeks worth of log backups local. We are currently limited to 2TB volumes from our san team, we can have multiple volumes but they are expensive ($200 per raw TB per month) and having to deal with many backup volumes instead of a single big volume is difficult. I think if we could have a shared network storage of 20TB+ raid 10 or so for all our servers for keeping the backups and another department will copy them to tape from the network storage and delete files according to the retention period would be good, if this box would be a build in operating system (even unix a complete file storage system) that would be good. What do you guys think, does this make sense to you, is there any manufacturer that sells a storage product like that which that work in a clustered environment? Thank you

  • Make logwatch reports more interesting?

    - by Alexander Shcheblikin
    Is it possible to improve the quality of reports from logwatch? Like make it not just report disk usage which doesn't even change much in daily operation, but report significant changes in usage or approaching critical capacity levels? If I cannot do that with logwatch and instead have to write custom scripts to produce such reports, logwatch appears to be pretty useless, or even dangerous, as many users reportedly grow to ignore emails from it knowing they are so boring.

  • 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?

  • Doing a mysql dump causes swapping issues

    - by DFischer
    I do a mysqldump manually every night. I just noticed that after it is done and I try to access the website it is very slow. After I take a look at the free -mh I notice that the server is now swapping when it otherwise wasn't before the mysqldump. What am I to do in this case? Just restart the server every time I backup? That doesn't seem very effective. My database file raw is 1.1gb after the dump.

  • IE9 freezes with Protected Mode enabled

    - by Peter Wone
    After a disk failure and a new build of Win7, IE9 locks up on most web pages including Bing. Running it as Admin works, and turning off Protected Mode also works. Neither of these was necessary prior to the rebuild and examination of colleagues' workstation config show that it's only my workstation with this quirk. Can anyone suggest a remedy? I have tried bcdedit /set {current} nx AlwaysOff and a reboot, with no effect.

  • Secure, efficient, version-preserving, filename-hiding backup implemented in this way?

    - by barrycarter
    I tried writing a "perfect" backup program (below), but ran into problems (also below). Is there an efficient/working version of this?: Assumptions: you're backing up from 'local', which you own and has limited disk space to 'remote', which has infinite disk space and belongs to someone else, so you need encryption. Network bandwidth is finite. 'local' keeps a db of backed-up files w/ this data for each file: filename, including full path file's last modified time (mtime) sha1sum of file's unencrypted contents sha1sum of file's encrypted contents Given a list of files to backup (some perhaps already backed up), the program runs 'find' and gets the full path/mtime for each file (this is fairly efficient; conversely, computing the sha1sum of each file would NOT be efficient) The program discards files whose filename and mtime are in 'local' db. The program now computes the sha1sum of the (unencrypted contents of each remaining file. If the sha1sum matches one in 'local' db, we create a special entry in 'local' db that points this file/mtime to the file/mtime of the existing entry. Effectively, we're saying "we have a backup of this file's contents, but under another filename, so no need to back it up again". For each remaining file, we encrypt the file, take the sha1sum of the encrypted file's contents, rsync the file to its sha1sum. Example: if the file's encrypted sha1sum was da39a3ee5e6b4b0d3255bfef95601890afd80709, we'd rsync it to /some/path/da/39/a3/da39a3ee5e6b4b0d3255bfef95601890afd80709 on 'remote'. Once the step above succeeds, we add the file to the 'local' db. Note that we efficiently avoid computing sha1sums and encrypting unless absolutely necessary. Note: I don't specify encryption method: this would be user's choice. The problems: We must encrypt and backup 'local' db regularly. However, 'local' db grows quickly and rsync'ing encrypted files is inefficient, since a small change in 'local' db means a big change in the encrypted version of 'local' db. We create a file on 'remote' for each file on 'local', which is ugly and excessive. We query 'local' db frequently. Even w/ indexes, these queries are slow, since we're often making one query for each file. Would be nice to speed this up by batching queries or something. Probably other problems that I've now forgotten.

    I am trying to install Ubuntu 10.04 LTS on my laptop. First I installed it inside Windows and when it boots for first time I got the error message "couldn't find root filesystem , try partition table to fix the problem " . When I want to install it on a single partition (normally) and when it told me to chose a partition I don't find any partition (entire disk) . I have 2 primary partitions and 3 logical partitions. How can I proceed with the install ?

  • 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!

  • Why isn't the backup file created when running sqlcmd from remote machine?

    - by Ed Gl
    I tried running the sqlcmd from a remote host to do a simple backup of a sql 2008 database. The command goes something like this: sqlcmd -s xxx.xxx.xxx.xx -U username -P some_password -Q "Backup database [db] to \ disk = 'c:\test_backup.bak' with format" I get a succesfull message but the file isn't created. When I run this on the sql manager on the same machine, it works. I thought it was permission problems, but I'm using the same username in both cases. Any thoughts?

  • How to encrypt dual boot windows 7 and xp (bitlocker, truecrypt combo?) on sdd (recommended?)

    - by therobyouknow
    I would like to setup a dual boot Windows 7 and Windows XP laptop/notebook computer where each operation system's partition is fully encrypted. I would like to do this on a SSD - a 128Gb Crucial M4. My research Dual boot of truecrypt encrypted OSs on one drive (not possible - in Truecript 7.x at time of writing) This cannot be done on a standard Truecrypt setup - it will only support encrypting one of the operating systems. I have tried this and also read about it here on superuser.com However, I did see a solution here that uses grub4dos as the initial bootloader to chain to separate truecrypt encrypted OSs, in my case Windows 7 and Windows XP: http://yyzyyz.blogspot.co.uk/2010/06/truecrypt-how-to-encrypt-multiple.html I am not going to consider this solution as it relies upon some custom code for use in the bootloader that is provided by the author. I would prefer a solution that can be fully understood so that I can be sure that there is nothing undesirable occuring (i.e. malware or just simply bugs in the code). I would like to believe such a solution doesn't have those risks but I can't be sure. BitLocker and Truecrypt combination - possible solution? So I am now considering a combination of encryption programs: I now aim to encrypt Windows XP with Truecrypt and Windows 7 with BitLocker. Assuming Truecrypt bootloader can boot into non-Truecrypt OSs (e.g. via hitting Escape to go to another menu), then this solution may be viable. SSDs and Encryption (use fastest possible spinning hard disk instead (?)) I read on various superuser.com posts and elsewhere that current SSDs are not suited to whole drive encryption for various reasons: impact of performance algorithms that give SSDs advantage over spinning harddisks. Algorithms used in compression of data for example. Wear on the SSD, shortening its life Security issues whereby data is repeated, as indicated in some Truecrypt documentation So I am now considering not using SSD. But with the aim to have the fastest drive possible, I am considering using the Western Digital Scorpion black 2.5" 7200rpm harddisk as this appears to be top rated among spinning platter-based harddrives (don't work for Western Digital). Summary So to achieve whole drive encrypted dual boot Windows 7 and Windows XP with minimal performance impact I intend to use a combination of Truecrypt and Bitlocker on a top-rated conventional spinning platter-based harddisk. Questions Will my summary: achieve whole disk encryption of the dual-boot Windows XP, Windows 7? OR an you suggest a simpler solution, including one that only requires only Truecrypt (BitLocker not available on XP). Or another encryption tool, including paid-for? provide the highest performance. Am I correct to avoid using SDD with encryption for the reasons I discovered? Are the concerns about SSDs and encryption still very real (some articles I read go back to 2010) Thanks for your input!

  • Does SDHC have any write error recovery ?

    - by marc
    What happen if SDHC card get write error (damaged cell / bad sector) ? Whole card is unusable (to trash, all data written to that sector now and in future will be lost) ? or rewrite sector (flash memory get corrupted when writing so maybe have any function to check if sector was written successfully) to another and mark as fault as unusable what will be seen as reduction of capacity but no data lost. I have to do some research about SD card-s on disk less machines. regards

  • Using Ubuntu switch a failing windows 7 harddrive?

    - by firefusion
    My laptop harddrive has developed some serious read errors in the windows partition. Windows 7 still boots but every single action takes an aeon, and it is definitely due to a harddisk error not due to any spyware. I'm using the Ubuntu partition now. I've ordered a new harddrive but my laptop didn't come with a Windows 7 install disk (I think I was meant to make one with the windows 7 tools). So how can I install Windows 7 on my new harddrive?

  • Sorting IPv4 Addresses

    - by Kumba
    So I've run into a quandary on sorting IPv4 addresses, and didn't know if there was a set rule in some obscure networking document. Do I do a straight sort on the raw address only (such as converting the IP address to a 32bit number and then sorting), do I factor in the CIDR via some mathematical formula, do I sort via the CIDR only (as if I'm comparing the network size and not the addresses directly)? I.e., normal math, we'd do something like -1 < 0 < 1 to denote the order of precedence. Given say, 10.1.0.0/16, 172.16.0.0/12, 192.168.1.0/24, and 192.168.1.42, what would be the order of precedence?
