• Files not accessible

  - by gokul

  My system is running on a pc with C:\ Drive out of space. So I tried to delete some file and clean up to get more space. I found that the %Temp% {C:\Users\Username\AppData\Local\Temp} takes lots of space and tried to delete files in it. But when I open it , it alerted me with the message C:\Users\Username\AppData\Local\Temp is not accessible The file or directory is corrupted and unreadable? What to do? Is deleting files from Temp harmful to computer?

• FoxPro 2.6 DOS on Windows 7 64-bit

  - by Rolando

  I support a company that has a very old, mission critical, FoxPro for DOS 2.6 (FPD) application. For variuos reasons the company didn't adapt/migrate their app, which, ironically, has been running even better under Windows XP (and 32-bit Win7) because the OS allowed new features like more reliable networking, distributed printing, email integration. Unfortunately for this company, most new machines now come with a 64-bit version of Windows 7, which is incompatible with their FPD app. I know this time the writing is on the wall: the only long-term solution is to migrate their app. But I wonder if anyone can suggest a temporary alternative path, which doesn't involve either: downgrade 64-bit Windows to 32-bit, or run the app on a virtualized 32-bit XP

• lvm disappeared after disc replacement on raid10

  - by user142295

  here my problem: I am running ubuntu 12.04 on a raid10 (4 disks), on top of which I installed an lvm with two volume groups (one for /, one for /home). The layout of the disks are as follows: Disk /dev/sda: 1500.3 GB, 1500301910016 bytes 255 heads, 63 sectors/track, 182401 cylinders, total 2930277168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0003f3b6 Device Boot Start End Blocks Id System /dev/sda1 * 63 481949 240943+ 83 Linux /dev/sda2 481950 2910640634 1455079342+ fd Linux raid autodetect /dev/sda3 2910640635 2930272064 9815715 82 Linux swap / Solaris Disk /dev/sdb: 1500.3 GB, 1500301910016 bytes 255 heads, 63 sectors/track, 182401 cylinders, total 2930277168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00069785 Device Boot Start End Blocks Id System /dev/sdb1 63 2910158684 1455079311 fd Linux raid autodetect /dev/sdb2 2910158685 2930272064 10056690 82 Linux swap / Solaris Disk /dev/sdc: 1500.3 GB, 1500301910016 bytes 255 heads, 63 sectors/track, 182401 cylinders, total 2930277168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdc1 63 2910158684 1455079311 fd Linux raid autodetect /dev/sdc2 2910158685 2930272064 10056690 82 Linux swap / Solaris Disk /dev/sdd: 1500.3 GB, 1500301910016 bytes 255 heads, 63 sectors/track, 182401 cylinders, total 2930277168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000f14de Device Boot Start End Blocks Id System /dev/sdd1 63 2910158684 1455079311 fd Linux raid autodetect /dev/sdd2 2910158685 2930272064 10056690 82 Linux swap / Solaris The first disk (/dev/sda) contains the /boot partition on /dev/sda1. I use grub2 to boot the system off this partition. On top of this raid10 I installed two volume groups, one for /, one for /home. This system worked well, I even exchanged two disks during the last two years. It always worked. But not this time. For the first time, /dev/sda broke. I do not know if this is an issue – I know I would have struggled anyways to overcome the problem with /boot installed on that disk and grub2 installed on the mbr of /dev/sda. Anyways, I did what I always did: start knoppix fire up the raid sudo mdadm --examine -scan which returns ARRAY /dev/md127 UUID=0dbf4558:1a943464:132783e8:19cdff95 start it up sudo mdadm --assemble /dev/md127 fail the failing disk (smart event) sudo mdadm /dev/md127 --fail /dev/sda2 remove the failing disk sudo mdadm /dev/md127 --remove /dev/sda2 stop the raid sudo mdadm -S /dev/md127 take out the disk replace it with a new one create the same partitions as on the failling one add it to the raid sudo mdadm --assemble /dev/md127 sudo mdadm /dev/md127 --add /dev/sda2 wait 4 hours All looks fine: cat /proc/mdstat returns: Personalities : [raid10] md127 : active raid10 sda2[0] sdd1[3] sdc1[2] sdb1[1] 2910158464 blocks 64K chunks 2 near-copies [4/4] [UUUU] unused devices: <none> and sudo mdadm --detail /dev/md127 returns /dev/md127: Version : 0.90 Creation Time : Wed Jun 10 13:08:46 2009 Raid Level : raid10 Array Size : 2910158464 (2775.34 GiB 2980.00 GB) Used Dev Size : 1455079232 (1387.67 GiB 1490.00 GB) Raid Devices : 4 Total Devices : 4 Preferred Minor : 127 Persistence : Superblock is persistent Update Time : Thu Mar 21 16:27:40 2013 State : clean Active Devices : 4 Working Devices : 4 Failed Devices : 0 Spare Devices : 0 Layout : near=2 Chunk Size : 64K UUID : 0dbf4558:1a943464:132783e8:19cdff95 (local to host Microknoppix) Events : 0.4824680 Number Major Minor RaidDevice State 0 8 2 0 active sync /dev/sda2 1 8 17 1 active sync /dev/sdb1 2 8 33 2 active sync /dev/sdc1 3 8 49 3 active sync /dev/sdd1 However, there is no trace of the volume groups. Rebooting into knoppix does not help Restarting the old system (I actually replugged and re-added the failing disk for that – the system begins to start, but then fails to see the / partition – no wonder if the volume group is gone) does not help. sudo vgscan, sudo vgdisplay, sudo lvs, sudo lvdisplay, sudo vgscan –mknodes all returned No volume groups found. I am completely at a loss. Can anyone tell me if and how I can recover my data? Thanks in advance!

• Hard Drive missing drive space

  - by Chance Robertson

  I have a 500 GB hard drive which I previously attached to my Mac. I detached the drive without going through the eject procedure. When I did this a message showed up, which of course I did not read. I could not use the drive until I formatted again. Now, when I attach the drive it says it is formatted NTFS and has 280.39 of 500 GB free. When I open the drive in Windows Explorer, Finder, or in Linux, is only shows a handful of files totaling 54 MB. How can I find out what is taking up all the space.

• DOS Batch file to find "new" files by date

  - by Todd McArthur

  My PC has entered an infinite BSOD loop - but I do have access to a safe-mode command prompt. I'm trying to get an idea of "what changed" that might have triggered this. e.g. I might have gotten a virus, or an app update went belly up. I'd like to thus see which files were created/modified in the last few days/week or at least the *.exe, *.dll, *.com, *.bat etc. I thought I was ok with my Batch-fu but I'm stumped on how to write a quick batch file/command that would list the files for me. REM This will find the files, but the results are all muddled REM all EXE files, reverse sort by date, recursively through sub-directories dir *.exe /O-D /S What I'd really like is to find all (executable filetypes) that were created/modified in the last 3-7 days. Can anyone point me in the right direction?

• What's the best way to clone multiple PCs from one machine?

  - by Jason T.

  Where I work we have dozens and dozens of old ThinkPad laptops. A lot of these can be reused but not for our needs. They have been long since replaced. The higher-ups have decided to donate them to charity. For better or for worse I have been tasked with reimaging them. I took a laptop and installed the factory copy of Windows, updated it, configured it appropriately. Now I'm trying to reimage it to dozens of other laptops. What's some good software to do this? First I used clonezilla to clone the hdd in the laptop to an internal drive in an external enclosure and it worked. Then I tried taking the base image out and connecting it externally to a laptop that needed to be imaged and I got it to work a few times. So far so good, right? Well once I informed my boss of my findings and what I would want to do then the images started to not work on new laptops. One of three things would happen: The Thinkpads would just blink at me and Windows wouldn't load. Or Windows would load but freeze within two minutes. Last but not least the laptops would BSOD during the Windows XP bootup. These laptops are not going to be used by the company. They're going to charity. So can anyone else recommend a way to reimage multiple laptops?

• Is Joerg Schilling's "sdd" a full replacement for "dd"

  - by fishtoprecords

  I'm trying to use 'sdd' on my Debian system, and can't get one set of options to work. They do work in 'dd' so I am wondering if I am specifying them incorrectly, or if sdd didn't implement them, or something else. What I want to do is sdd if=/dev/hdh1 of=/bay5/imagebay1 bs=4096 conv=sync,noerror if I leave out the "conv=..." option, it works, or at least starts copying data. sdd if=/dev/hdh1 of=/bay5/imagebay1 bs=4096 Can you shed a bit of light?

• A space-efficient guest filesystem for grow-as-needed virtual disks ?

  - by Steve Schnepp

  A common practice is to use non-preallocated virtual disks. Since they only grow as needed, it makes them perfect for fast backup, overallocation and creation speed. Since file systems are usually based on physical disks they have the tendency to use the whole area available1 in order to increase the speed2 or reliability3. I'm searching a filesystem that does the exact opposite : try to touch the minimum blocks need by an aggressive block reuse. I would happily trade some performance for space usage. There is already a similar question, but it is rather general. I have very specific goal : space-efficiency. 1. Like page caching uses all the free physical memory 2. Canonical example : online defragmentation 3. Canonical example : snapshotting

• How can I create bootable DOS usb stick?

  - by Grzenio

  I need to use this utility to change one of the parameters of my new WD hard drive: http://support.wdc.com/product/download.asp?groupid=609&sid=113&lang=en It has truly unreadable instructions: Extract wdidle3.exe onto a bootable medium (floppy, CD-RW, network drive, etc.). Boot the system with the hard drive to be updated to the medium where the update file was extracted to. Run the file by typing wdidle3.exe at the command prompt and press enter. I understand that this bootable medium should be some version of DOS? How can I make my USB stick a bootable medium compatible with this utility (I don't have a diskette drive)? I have Windows 7 and Debian Linux installed.

• hiberfil.sys and pagefile.sys... rebuilt on boot?

  - by spender

  I need to take an image of a drive. I'm working from a bootable CD, so I have the option to decruft before taking the image. The Windows installation on the drive has both hyberfil.sys and pagefile.sys which I would rather not include in the image. If I delete these from the drive, will Windows recreate these files if necessary? EDIT The Windows installation on the drive in question was shut-down cleanly.

• Caching/preloading files on Linux into RAM

  - by Andrioid

  I have a rather old server that has 4GB of RAM and it is pretty much serving the same files all day, but it is doing so from the hard drive while 3GBs of RAM are "free". Anyone who has ever tried running a ram-drive can witness that It's awesome in terms of speed. The memory usage of this system is usually never higher than 1GB/4GB so I want to know if there is a way to use that extra memory for something good. Is it possible to tell the filesystem to always serve certain files out of RAM? Are there any other methods I can use to improve file reading capabilities by use of RAM? More specifically, I am not looking for a 'hack' here. I want file system calls to serve the files from RAM without needing to create a ram-drive and copy the files there manually. Or at least a script that does this for me. Possible applications here are: Web servers with static files that get read alot Application servers with large libraries Desktop computers with too much RAM Any ideas? Edit: Found this very informative: The Linux Page Cache and pdflush As Zan pointed out, the memory isn't actually free. What I mean is that it's not being used by applications and I want to control what should be cached in memory.

• Linux: Is it safe or recommended to rearrange partitions through SSH?

  - by GetFree

  I've just rented a new server (CentOS 5.4) and I see it has only 3 partitions: /, /boot and the swaping partition. I'd like to create, at least, partitions for /tmp and /var. Would there be any problems if I try to create those new partitions through SSH?? Thanks.

• Why can't I create a Windows backup on my secondary disk?

  - by Brian Sullivan

  I've installed Windows 7 Ultimate on an SSD that I've added to the XPS desktop that I bought from Dell. I would like to use the built-in backup functionality to create incremental backups and store them on the large drive that came with the machine. I formatted the large drive and turned it into a Basic disk. However, when I try to set the backup location to the large internal disk (E:\) in the "Set up backup" wizard, a get a message saying, "A system image cannot be saved on a drive that your computer boots from or that Windows is installed on." Windows is not installed on that disk. I even deleted the OEM partition that was on the disk, and removed it completely from the boot order in the BIOS. Any clue why Windows is griping at me about this?

• Bad performance with Linux software RAID5 and LUKS encryption

  - by Philipp Wendler

  I have set up a Linux software RAID5 on three hard drives and want to encrypt it with cryptsetup/LUKS. My tests showed that the encryption leads to a massive performance decrease that I cannot explain. The RAID5 is able to write 187 MB/s [1] without encryption. With encryption on top of it, write speed is down to about 40 MB/s. The RAID has a chunk size of 512K and a write intent bitmap. I used -c aes-xts-plain -s 512 --align-payload=2048 as the parameters for cryptsetup luksFormat, so the payload should be aligned to 2048 blocks of 512 bytes (i.e., 1MB). cryptsetup luksDump shows a payload offset of 4096. So I think the alignment is correct and fits to the RAID chunk size. The CPU is not the bottleneck, as it has hardware support for AES (aesni_intel). If I write on another drive (an SSD with LVM) that is also encrypted, I do have a write speed of 150 MB/s. top shows that the CPU usage is indeed very low, only the RAID5 xor takes 14%. I also tried putting a filesystem (ext4) directly on the unencrypted RAID so see if the layering is problem. The filesystem decreases the performance a little bit as expected, but by far not that much (write speed varying, but 100 MB/s). Summary: Disks + RAID5: good Disks + RAID5 + ext4: good Disks + RAID5 + encryption: bad SSD + encryption + LVM + ext4: good The read performance is not affected by the encryption, it is 207 MB/s without and 205 MB/s with encryption (also showing that CPU power is not the problem). What can I do to improve the write performance of the encrypted RAID? [1] All speed measurements were done with several runs of dd if=/dev/zero of=DEV bs=100M count=100 (i.e., writing 10G in blocks of 100M). Edit: If this helps: I'm using Ubuntu 11.04 64bit with Linux 2.6.38. Edit2: The performance stays approximately the same if I pass a block size of 4KB, 1MB or 10MB to dd.

• What is the best drive cleaner?

  - by allindal

  What is the best drive "cleaner" application, an application that deletes roaming, temp. and different useless caches. Something similar to CCleaner, but more powerful. I need it to delete more than the basic stuff. Like duplications of complex files or redundancies, (example... for every game there's the DirectX suite) without deleting program essential files, obviously. I know most of this has to do with my selection of these programs, but I haven't seen anything that lets me select types of files to delete, not just specific files.

• Can someone implement LVM on an existing single-hard disk system ?

  - by jfmessier

  I am using SuSE Linux (10) and I am considering expanding the available disk, without resizing an existing partition (which is not easy to do on a VM). Instead, I want to create another virtual disk, and add it in a new LVM volume, which would include the existing disk, and this new one, in a seamless single mount point. We are using VMware vServer 4, under Lab Manager and Virtual Centre. Does SuSE support LVM in version 10 ? Thanks :-)

• Recommended drive encryption solution

  - by Chris Driver

  Hello, I will soon be purchasing a number of laptops running Windows 7 for our mobile staff. Due to the nature of our business I will need drive encryption. Windows BitLocker seems the obvious choice, but it looks like I need to purchase either Windows 7 Enterprise or Ultimate editions to get it. Can anyone offer suggestions on the best course of action: a) Use BitLocker, bite the bullet and pay to upgrade to Enterprise/Ultimate b) Pay for another 3rd party drive encryption product that is cheaper (suggestions appreciated) c) Use a free drive encryption product such as TrueCrypt Ideally I am also interested in 'real world' experience from people who are using drive encryption software and any pitfalls to look out for. Many thanks in advance... UPDATE Decided to go with TrueCrypt for the following reasons: a) The product has a good track record b) I am not managing a large quantity of laptops so integration with Active Directory, Management consoles etc is not a huge benefit c) Although eks did make a good point about Evil Maid (EM) attacks, our data is not that desirable to consider it a major factor d) The cost (free) is a big plus but not the primary motivator The next problem I face is imaging (Acronis/Ghost/..) encrypted drives will not work unless I perform sector-by-sector imaging. That means an 80Gb encrypted partition creates an 80Gb image file :(

• Is it possible to FORMAT an external hard disk that has been encrypted using Storagecrypt?

  - by Pandian John

  Basically the big problem is that about 680 GB of data from my Seagate 2 TB Ext HD is lost because I was experimenting with a software called storagecrypt. I used it a few months ago and today I tried it again but i didn't know that the old password is already set in the hard disk when I pressed the encrypt button. I forgot the password which is disappointing. Not to mention that software uses 128 bit AES encryption so there is no way iam going to recover that data. My question is that is it possible to Format my Hard disk which has been encrypted? What i mean is that is it possible to completely wipe the data just like it is newly bought so that I can use my External Hard disk?( I tried to format by right click-- Format. But the size of the disk is shown as 1 MB. Answers would be very much appreciated. Thanks.

• How do you passthrough native SATA drives to a guest on ESXi?

  - by John

  I have ESXi 4.0 running on an Intel DX58S0 Mothboardboard with an Intel Core i7 930 processor. VT-d is also enabled. I have three drives in the system, drive 0 is used for ESXi. Drive 1 and 2 contain data from an older machine and show up under the "Storage Adapters" section in configuration. I would like to allow a guest machine to access the data on these drives (as nativly as possible). I have enabled passthrough of the motherboard's built in SATA controller (Intel/Marvell 88SE6121 ). This controller shows up in my guest OS, but the guest shows no drives aside from the normal virtual drive. I have tried a Linux guest and Windows7. I have also configured the host machine to try IDE/RAID/ACHI modes for the SATA controller. Any ideas how I can configure one of my guests to get at the raw data on these drives?

• How can I detect hard drive failures?

  - by Francis

  I am in charge of a large number of Windows servers. Recently, many have been reporting hard drive errors with event codes 11 and 55. CHKDSK indicates that the drives are fine most of the time. What other diagnostic tools could I use to more accurately detect hard drive failures? Could these Windows events be false positives? I have already evaluated S.M.A.R.T., and it seems to have significant sensitivity and specificity issues.

• Can't find partition tab in disk utility osX ver. 10.6.8

  - by John W

  I just got a used Mac Book Pro. I created a new admin account and deleted the old one as well as one other user. This is an older late 2007 MBP... the osX upgrade to 10.6.8 was just performed. My Macintosh HD is showing up as Partition 2. I ran disk utility (not from install disk), but there was no partition tab. I have a 160GB drive with only 53GB of space left on it. Since I am the only user and have no files on the laptop yet, I don't understand why there is so little space left. Surely the OS can't use up over 100GB. I wanted to run disk utility to see if there were any recovery partitions or other partition left over from the previous owner that could be erased to make room for expanding the main partition. Unfortunately, there is no partition tab in disk utility. The documentation I have found on line states that this version of osX includes that utility. The osX disks I have are for an older version so I wasn't sure if they would be of any use in solving this problem. Also, I was afraid if using the disks, would I lose the little bit of data/apps that I have assembled. I would rather not do a fresh install and have to do all the updates again to achieve this. The previous owner had some apps that I don't want to lose as I would have to pay handsomely to get them back. Simply, if all the previous users data is backed up on here after deleting user is still taking up space on a recovery partition (that I can't see)... I need to locate it erase it and expand the primary partition to re-aquire disk space for my files. I am new to Mac, so please be as descriptive as possible. Thanks.
