Debian :: Brasero Always Passes Image Integrity Checks?
Feb 9, 2011
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.

I'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.

After upgrading to Lucid RC I notice that I cannot create a CD image anymore. Brasero gives me three options : two .toc and one .cue file format but neither of them work the CDDAO variant of the .toc format gives me a notification that i need to install some extra packages but even after installing those, the image creation hangs. I used to be able to create .iso images but that option has completely gone...

I'm using Ubuntu 9.1 to try to make a disk image of my Windows operating system that I'd like to save to an external hard drive. Currently, I'm just running Ubuntu off the cd. Having checked the "Ubuntu Software Centre" on my computer, I notice that it has Brasero installed, and I was wondering:
1) First off, where can I find it? (Is there a search function in Ubuntu like Windows?)
2) Is Brasero a good choice to create a disk image?

When I first installed K3b it burned the first track with no GUI user configurations.The second time it says that the file name is too long and asks if you want to catenate (shorten) it even if it is the same file you have already burned that didn't ask for this shortening of the file name before. Than it gives you an error of "Could not determine size of resulting image file". So my question is how do you use K3b I guess. Brasero won't do multi-session as far I can deduct. It will ask if you want to do it but after ask if you want to erase the disc.If you force it there is no entry of the previous burns.If I could get Brasero to muli-session it would sovle my problem as well. Here's the debugging stuff. I'm using this on Gnome.

K3b Version: 1.0.3
KDE Version: 3.5.7

I'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 recently tried to burn an ISO image to a DVD. Everything seemed to be going fine except Brasero froze at "Finalizing". It stayed there for about 10 minutes before I gave up. When I hit cancel nothing happened. When I tried to eject the drive nothing happened. Not until I shut the computer down and restarted was I able to open my DVD drive. Upon trying to read the disc no computer shows that it has anything on it.

I've been running 10.04 server for 3 months from a fresh install. I have been installing updates while Bind9, Apache2 and Samba worked just fine. The last time I installed updates was 3 weeks ago and it worked just fine.
Today I ran into problems where the system stopped doing its DNS stuff and wouldn't respond to pings over the network. Since I couldn't get it to respond with a keyboard and monitor attached to it I shut it down through the power switch. I then tried to restart the machine and all it would do was go through the bios and show a cursor flashing in the upper left or this odd color pattern on the screen and then reboot
I have tried pulling the HD and loaded it into my Ubuntu desktop and loaded the file system just fine. I then tried using the "rescue a broken system" option Ubuntu 10.04 32bit install disk and it seems to just sit at a flashing cursor.
I've seen some odd things pop up on the screen at times but mainly would be a flashing cursor in the upper left part of the screen.

I've got this really weird problem and I'm not even sure if it is a problem. I recently upgraded the RAM on my Compaq Presario Laptop from 3GB to 4GB by swapping out a 1GB DDR to a 2GB DDR so now it contains two 2GB DDRs. The BIOS shows 4096 MB of memory, Fedora shows 3955MB (Probably after the reduction for the video memory) so that's fine.
But I noticed a very quick flash during boot in between the Compaq Screen and GRUB. It only started coming after the RAM upgrade. I'm not able to make out what exactly is written. It's too fast. Will try with a proper camera at home. In any case, I could make out some large number probably in the order of gigabytes written in bytes. Again, not sure of the exact value.
So I get a little curious about this message and decide to run a memory test. It's working perfectly. Around 74%, it stops and says Memory Test Passed and moves on to check the HDD. I try the same from the BIOS. In the BIOS, it's a progress bar and no percentage value mentioned. Though the BIOS says 4096MB of memory, the progress bar also stops at roughly 75% and says passed. I'm not even sure what to search for on Google though I tried and got no similar results.
why this is happening? Since it's stopping at 75%, I have a feeling that the change in the amount of RAM hasn't been made in some place by the system.

I have a Canon iR3570/iR4570 PXL, and installed the driver CQue 1.0 TCP/IP Queue from Canon webpage.
The problem:
- if i try to print an OpenOffice or LibreOffice Calc with an image and text, the image is not printed (the space is blank).
- if i try to print an OpenOffice or LibreOffice Calc with just an image, it's printed great.
- if i try to print an OpenOffice or LibreOffice Impress, the images are not printed but the text is printed great.

A computer upgraded from 7.3 to 8.2 suffered a number of stability issues which were traced to systemd having replaced sysvinit in this version. Worst of these was that instead of shutting down it just cut the power instantly, causing disk corruption. Basically, from what I can find out, this systemd component seems like it works OK on a completely fresh install but causes multiple issues if it finds its way onto an updated system. I found some instructions on reinstating sysvinit, which cured the issues.
However, on attempting to install the Brasero CD/DVD app via synaptic, I notice that this will force reinstallation of systemd as a dependency, even though it's been locked-out of updates. Luckily I spotted this in time and cancelled. You really wonder why a CD writing app would need to do this. I certainly seems rather naughty for any desktop package to be changing system startup code in a manner which could break the OS.
At the moment I'm not sure if it's the only app which does this -although k3b seemingly does not. Any thoughts on this gotcha, and how to prevent a repeat, other than being extremely careful when installing anything?

WTF why is it with every update the devs try to break something. Might as well be using Ubuntu at this point and No I do not want to install Stable. Todays updqate would bring in linux-image-2.6.39-1-686-pae linux-image-686-pae, but my CPU Single core Intel Pentium M (-UP-) cache 1024 KB flags (sse sse2) bmips 1196.07 clocked at 600.00 MHz doesn't use PAE so it told me to remove linux-image-686 and to install linux-image-486. So more shiny crap that doesn't support older hardware, it is getting to be as bad as Microsoft.
Why don't I just go upgrade or buy new hardware with every new shiny crap that wants to upgrade. If it isn't broken do NOT fsck with it.

Ubuntu 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.

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.

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?

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 checked my DNS settings, my DNS server, and everything was good to go. I even removed all files from /var/lib/clamav, including the mirrors.dat file, and still no go, got the same errors. I downgraded all the packages, and still got the same thing... Is anyone else having this problem?
