is there a way to "repair" or check the integrity of ogg files? They all work on my desktop but some seem broken on my mobile (Nexus One). I have the feeling my converter may have corrupted some files or the conversion was corrupted by the original file.
View 3 RepliesUbuntu 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.
I 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.
create 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?
I have been using the new ocr app 'cuneiform' that has appeared in the Lucid repo.It is command line and works very well.However, the rest of the household would like to use it and desire a gui front-end.Mepis has this and it is called YAGF. Works well.We are told to install only from trusted sources.how can I check the integrity of this .deb and freedom from malware before installing it?
View 5 Replies View RelatedI botched up adding storage to an existing volume group. The original volume is still intact and working fine, but the management utilities show I have an "unknown physical volume" as part of the group. That happened because I did things out of order and dropped a partition with fdisk before removing in LVM. So now it says it can't remove the volume because it can't find device with UUID Mt6...
Am I correct in thinking that if I restore a *.vg file that describes the lvm state before the botch up from /etc/lvm/archive to /etc/lvm/backup, then re-start the system, I'll be able to find and remove UUID Mt6....... and then start over doing things in the proper order?
I want to get rid of the "unknown device" record and add the "New Physical Volume" at /dev/sdb1 to the volume group. I'm concerned about adding the new pv with the bogus record still in place. I need this volume group to be stable! Attached is a txt file with output from "dmsetup info" and "pvdisplay".
sudo got broke somehow and now some folders have wrong or broken ownership. should I chown these files to my logon or wa?

Is 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.
View 1 Replies View RelatedI'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.
I am experiencing some strange behaviour with sound, and I have been messing around with installing some ALSA drivers. I suspect that I might have corrupted some part of the installed Ubuntu packages. Is there a way to check all the packages on the system for integrity using apt-get or similar?

View 2 Replies View RelatedI'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.)
I'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.
