Software :: Raw Device Data Integrity Test Tool?
Jan 6, 2010I've been looking for a good data integrity test tool for linux, but I'm having trouble finding one. Basically I'm looking for an application that will generate a heavy I/O load to a raw device and then perform some kind of data verification on the device. I my case the raw device will be md raid5 array.

Jul 28, 2009I have a seagate SATA hard drive that was running a mythtv distro. It had 3 partitions, EXT3, swap, and XFS. I started having I/O errors on boot and saw error messages on both the EXT3 and the XFS partitions. I also heard some clunking sounds on the drive when it was reading, so I thought hell, the drive is dead.
I have since replaced the drive and everything is back up and running on the replacement drive. I thought hell, the seagate drive is toast, but I just want to verify it with some sort of tool. I have the hard drive in a Vantec NexStar external hard drive case (SATA->USB) and found there was a tool called badblocks. Ran badblocks on it, which ran for 24ish hours and found no bad blocks. I also didn't notice any clunking sounds while it was running.
I ran
Code:
badblocks -n -v /dev/sdb
Is badblocks a proper test to run on external hard drives or was I just wasting my time? Is there any way that I can really test it without removing it and connecting it with SATA to the motherboard?
OpenSUSE Hardware :: PolicyKit: Only One User Can Mount USB Sticks
Jan 31, 2011Looks like its some sort of PolicyKit issue. Documentation (and I suspect the system itself) all assume that I have only one user. But my computer is a two-seat, my girlfriend and I are logged in at the same time. Only I am able to mount and write to USB drives. I suspect its because my account is always logged in first.
Dolphin gives the following error: org.freedesktop.Hal.Device.PermissionDeniedByPolicy
blah blah org.freedesktop.hal.storage.mount-removable auth_admin_keep_always
So my guess is that this "auth_admin" for some reason only refers to my user. I opened up the "Global Configuration" application (something that typed up when I filtered for 'policy' in the application launcher), and added my user, my girlfriends user and the 'user' group as "System Administrators". I logged out and logged back in on her account and this did nothing.

View 1 Replies View RelatedUbuntu :: How To Check Integrity Of Install CD
Nov 23, 2010Ubuntu 10.04 32 bit. I am familiar with the option on the alternate CDs to check CD integrity. Is there such a thing for the normal desktop live/install CD? I know the download image is OK. I have created several virtual machines from it. I believe the CD is OK - I have installed 2 physical machines from it.
I am now installing on my old Dell Poweredge 400 SC. When I first boot from the CD I get the message "The installer encountered an unrecoverable error..." then it brings up the Live CD OS. From there I can manually run install. The first time it got about half way through copying files to the hard drive and died. It indicated an I/O error. Could be dirt in the DVD drive - it is older than dirt. Or it could be the CD. Dirt I can clean with some compressed air. How do I verify the CD? I am downloading the alternate CD now as I try a second run at installing.

View 2 Replies View RelatedHardware :: Booting From CDs And USB Sticks
Jun 14, 2010When first a regular HDD boots up, the BIOS passes control over to the first 512 bytes of the disk, so long as the disk has the magic number (correct signature) at the end of this first sector. The BIOS doesn't 'care' what is in this first sector; it just passes control over to the code within it and hopefully boot-up is underway. Other boot instructions may commonly lay elsewhere on the disk, which is fine, since the boot sector code will point to them and the process goes on.
Now, what happens when you boot from a CD or a USB stick? Not quite the same thing happens, does it? What I need to know is, when booting from alternative media, what is the BIOS 'looking for' and whereabouts on these new media does it expect to find the boot code? I've looked at the directory structures of CDs and sticks and there doesn't seem to be any common factor in the files and directories there that I can identify, unlike when I examine a regular HDD and its partitions with a hex editor.
Ubuntu :: Integrity Checker With Recovery Records?
Feb 28, 2010Is there any software to store recovery records that can be used for recovery from data corruption, like RAR does? I periodically rsync from a primary backup location, that I assume corruption-free, to a secondary one, that I consider corruptible - so I'd like to store in the destination some recovery data.

Jun 30, 2010I've tried to install Linux Ubuntu 9 on an HPmini 110, since this type of netbook doesnt have any optical unit (CD/DVD Reader) I decided to install Ubuntu from an USB flash drive, I created the booteable USB drive with Lili USB Creator, then when I reboot the HPMini and select the "check integrity" option before install, it's always the same error, when the check is finished it tells me "Encountered 1 error in 1 file" (With no description of this error whatsoever) even when Lili USB Creator previously did a succesfull integrity check of the same ISO I'm trying to install.
I'have installed this same version of linux before (on the same machine), from the same ISO image without this error, I also have tried with 3 different flash drives and lately even tried downloading again the ISO image of Ubuntu 10, I dont think is my hardware either since Ive tried to install this same image in 2 different laptops 1HPmini and 1 HPCompaq CQ60 with the same results at the integrity test.

View 1 Replies View RelatedUbuntu :: Check Harddisk And File Integrity?
Aug 12, 2011I want to get a program to check (a) hard disk and (b) file integrity. I have had a file - ODS spreadsheet accessed using LibreOffice - that appears corrupt. I have drilled down and down and eventually identified a corrupt component image inserted in a sheet.
The error that is thrown by LO is a "Error saving
the document FILE: Write Error. The file could not be written."
error. The thread can be read here... http://thread.gmane.org/gmane.comp.d...fice.user/9266.
What has confused me is that my machine can not save the file once a sheet is deleted. It is specific to a particular file. The file is stored on n ext4 disk mounted by fstab. I also share the file using samba. Regardless of how I access this file I get the error. If however, I access the exact same file using OpenOffice 3.1.0 OOO310m11 (Build: 9399) from an old Windows Vista Tablet and I can manipulate the file successfully - no error is encountered. I can also access the same file from another Ubuntu machine via NFS and Samba and both work. I am confused. I am beginning to think my disk is damaged or something. How do you check hard disks to verify that the disk surface is intact, and that the expected file sum value matches the value stored in the Linux equivalent to the FAT table.
I am using Ubuntu 10.04 LTS and all hard disks are formated with ext4. All formatting and management of the disks have been done using the 'Disk Utility' in the System > Administration' menu. If I look in gparted it will not check the disk the file is on stating "eslabel: no such file or directory... couldn't find valid filesystem superblock...". The filesystem mounts OK however without any errors. Another harddisk on the same system currently being used for backup does not even have the menu option for checking the disk highlighted.
What is the best way of verifying the integrity of the filesystem, actual files and the underlying physical media? I should point out it is only this single file that currently displays any issues. I either have a damaged disk, corrupt file or LibreOffice has a very peculiar bug that only appears in a unique combination of events just on my machine. As part of my investigations I have been updating ubuntu, reinstalled LibreOffice from their website and checked all dependencies have been met.
General :: Can I Do Integrity Check When Tar.gz File Is Created?
Mar 25, 2011create one tar.gz file that contains my /home, /etc, /root directory.
a) The process ended with a 88GB file size (which is ok) but with the following message.Code: tar: Exiting with failure status due to previous errors.I have searched a little but I could not find what went wrong.
b) What are the limitations of tar and gz for backups. Of course I fully understand that they can not be used for differential backups (if it is called like that)
c) Let's say that my backup will be a file of 100GB and I want to see the contents of the .tar.gz. In kde there is a program called ark. Can ark handle so big files? Does it use my hard disk (eg. /tmp) to uncompress the file so to show me its contents? It might be the case that might be the compressed file is much bigger than the left space on the hard disk?
d) How can I do an integrity check when my tar.gz file is created?

Ubuntu :: Cannot Write To USB Sticks And SD Cards?
May 27, 2011I am running a dual boot system Ubuntu 10.04 (32 bit) and Windows 7 Home Premium (64 bit) on a Dell Inspiron 540s. I currently have an 8 GB USB stick inserted in a 4 port USB hub. I can read files on the device but I cannot write to any of the files. Using the ls and chmod commands I get the following outputs. Note that after assigning rwxr to all users nothing changes. Incidentally, since I could not write to the stick I created a text file in windows and saved it to the USB stick as a text file.
ubuntu:~$ ls -l /media/usb/file3.txt
-rwxr-xr-x 1 root root 6 2011-05-27 15:17 /media/usb/file3.txt

View 4 Replies View RelatedDebian :: File Integrity For Backups Of Home Data ?
Nov 17, 2010I'm currently backupping our home data (pictures, videos, our CDs ripped to FLAC which I spent a lot of time to tag accurately ), totalling almost 300 Gb, on 2 external USB drives, one of which is meant to stay at a friend's. I left the factory msdos filesystem as it was, thinking it could be useful to be able to connect the drives to a windows machine with no problems. It's certainly useful to have «normal» data that I can take with me e.g. when visiting my family.
I'm simply using rsync manually, checking for suspicious changed or deleted file before commiting the change. I do that every 2 weeks or so.
Now I want to add a file integrity management to my backupping scheme: I want to be able to check that new data I'll be committing has not been tampered with (integrity check before updating tags on my main drive), and I want to be able to check that backupped data is still sane on my USB drives, especially if I need to recover from data corruption on my main drive.
Since I'm essentially mirroring the data, I thought run of the mill integrity software would let me just rsync the integrity database, and I'm done.
But after browsing through the docs of tripware, afick and the like, I fear they work only with absolute paths, so the database for my main drive wouldn't work for my USB drive, that's mounted elsewhere when I plug it in, obviously.
So, I feel I'm missing something. It looks to me I'm trying to solve a very common problem, how do people do it?
Did I miss a file integrity software that works with backups?
Is there a trick like using a symbolic link pointing to whatever file hierarchy I want to check, and have tripware/afick/... monitor that link?
Should I run a more elaborate backupping system than plain rsync? Which one? (Storebackup for instance looks promising since it involves md5 sums, but it's targetting a completely different problem, and I'm not sure I can use it at all for what I need.)
Debian :: Brasero Always Passes Image Integrity Checks?
Feb 9, 2011I've been using Brasero to burn iso images on DVD-Rs, and although the burns are successful (I know by testing them), Brasero doesn't seem to perform its file/image integrity check from Tools>Check Integrity. The Brasero plugin "File checksum" or "Image checksum" is checked (can't have both checked), and when I perform a manual check with an md5 file and its burned DVD,it"always" gives me, immediately, a success message: "the file integrity was performed successfully," even when I insert a different image with the previous md5 file! So, immediate response (doesn't seem to be checking anything, I know that a 4Gb DVD md5 checking should take some time), and success whatever the DVD image used with one md5 file. Something must be wrong or the feature is broken.

OpenSUSE :: Test Out Restoring The Database?
Sep 19, 2010I currently backup my database using MySQL Administrator. I wanted to test out restoring the database, so on my test server I deleted the database and restored the .sql file to a new schema with the same name as the old. one. It appears to complete the process just fine. But I noticed that the number of rows for the restored database is slightly less than what was backed up.
Is this normal or should the numbers be exactly the same? It's only a difference of about 28 rows. I seem to be able to view the data just fine in the query tool.
