Ubuntu :: Burned Important Data To Disc- Unreadable?
Aug 16, 2011
I think it is a bug that has been reported already. https://bugs.launchpad.net/ubuntu/+s...ols/+bug/46966
Except I was using a cd instead. I was trying to install a different linux distro so I put all of my important documents on a disc. The disc shows it has contents before I try to open it but when I do the disc shows to be empty. I'm trying to open it in both windows 7 and linux ubuntu.I just need to get these documents back.

I've been using Excel from OpenOffice with moderate success for the last year. Now I've just tried to open a new spreadsheet and I'm suddenly getting a highly condensed view. The cells are about 1mm X 4mm. If I expand them by selecting and dragging, then try to copy data from another spreadsheet onto the new one, the data shrinks to the small scale -- unreadable.

I set up a data project to burn a bunch of files onto a CD. I want to backup the files. I went to edit > plugins and selected "File Checksum" and set it to SHA1. Will Brasero now automatically (as part of the burning process) calculate and then compare the SHA1 for the file on the HDD with the file that is burned to the CD? If the two SHA1 comparisons do not match then Brasero will kick up a dialog window alerting me? Do I understand how this works correctly? as long as the plugin is enabled this is all automatic? Is the "Image Checksum" plugin only in use when I am burning an ISO?

I installed windows 7 over an existing xp partition and windows 7 made a 100 mb partition as some sort of windows swap space thing. This basically made my ubuntu partition unreadable, even with gparted. How to recover this data?

I'm using Ubuntu 10.04 and am trying to use it to recover data from a failed External HDD (NTFS).
The drive failed with an accompanying smell of electric burning and subsequently was not recognised by Windows. It would recognice the enclosure, but told me that the drive had to be reformatted.
I removed the drive from the external enclosure and hooked it up to my PC with a power cable and USB to SATA connector. I can mount the drive in Ubuntu (eventually) and I've learned enough about BASH to navigate through the files on the drive.
Those that I can access I am able to copy across to my internal drive (VERY slowly, but it does do it) but a lot of the directories show up with an Input/output Error when I run the ls -l command.
Is there any way for me to be able to access these files or to recover them? Should I be trying a different technique rather than just attempting to access and copy the files?

I have a new system using an Intel DG451D main board. I have been trying to get a RAID 1 mirror set working as the main drive in this system and for some reason, my SATA drives - three of them all new have had their SMART data changed to show the drives as failing and in need of replacement. Eventually the drive reports failure to the degree that the BIOS no longer recognises it. When loading the Centos os I was getting differing results because of this issue. I am not sure if this is a hardware issue even - I know that the drives were all very much OK and brand new - no good now! Just putting a feeler out to see if anyone has had a similar issue or to see if anyone knows of any possible known causes for this?
Failing any explanation, can anyone suggest a good desktop style Main Board that supports RAID well for Centos 5.4? I plan to sue this as a small server system so graphics etc are not important here.

this blew my mind today, because i've been using ubuntu for 2 and half years. Brasero 2.28.2 in Karmic does not have an option enable multisessions when burning disc or import a disc which has a multisession.
Seriously, wtf is going on? This is supposed to be Ubuntu's default CD authoring software.

I'm trying to install files and everytime I manage to install from the first disc I succeed. When I get the the second disc I just keep clicking the "OK" button instead of "Cancel" and it keeps neglecting it.

I have just installed 11.3 x64. The installation went fine and worked for the first few hours. I ran the online update tool, and now it cannot find grub unless the installation disc is inserted and I select the "boot from hard disc" option.
I have read about the problem of the root partition being back, but not sure that's it.
sda1 - swap
sda2 - /
sda3 - /home
There used to be a repair tool in the installation disks. I could not find that in this media. Is that still available?

I'm sorry for this stupid question, but I have nowhere found it.I need to access to my USB disc from text mode (In Fedora LiveCD I see it and i can access /media/New Volume). In F12 runlevel 3 in mc I see it in /dev/disc/by-label as @Newx20Volume. But I don't know what is the correct path.

I've been backing up some data recently because I'm planning to upgrade to 10.04. It had been going well until today. I burned a couple DVDs, tested them, and they were fine. I burned another one, tested it, and it wouldn't mount. Got the following: "Unable to mount media. There is probably no media in the drive." (Was using K3b).
I tried the same one again, this time using GnomeBaker. Seemed to burn alright, but once again would not mount when I tested it. So, I thought maybe it's just this one particular folder. I tried to burn a DVD with completely different data. Same thing, seemed to burn OK, but again it will not mount.
I went back and re-tested the DVDs that worked OK earlier today, and these ones are still mounting. Any ideas? Did my burner suddenly go bad? Or does someone know of any other possibilities that hopefully could be fixed? -using Verbatim 16x DVD-Rs (burned on 8x)-Lite-On SHW-160P6S
-Ubuntu 8.10
-755 MB RAM
-Intel Xeon CPU 1.70GHz
-used no multisession (or finalized in Gnomebaker)
-used linux+windows filesystem
-I was burning mostly video files (.avi, a couple of .wmv, couple of text files, subfolders with other .avi, etc.)--basically the same type of data whether they could mount or not.

how to read a CD, burned by a Mac, on my Ubuntu machine. Is there any way possible to do this? I'm sure there would have to be a way because, well, Mac and Ubuntu have their similarities..

May be out in left field here so bear with me . If i have two iso movie burns whose total gb data is 4.7 or under can both be burned to a single disk using K3b ? Not clear on whether to burn iso image in devede as two separate burns or combine as one iso image . If burned separately in devede don't see how to put both on same dvd when using K3b > video project . New to this so maybe "can't get there from here " .

I've been trying for days now to install Ubuntu on a Dell Dimension 5100 desktop. It's got a 2ghz processor, ATI graphics card and 512 ram. It has a DVD drive that it boots from. Here's the problem. I have Ubuntu 10 burned on a regular CD and I have Ubuntu 9.1 burned on a DVD. I can boot this Dell up using the CD. It goes through the regular install, gets to 23% then tells me that it can't recognize the CD/DVD device or the hard drive. I've re-seated cables, I know the hardware is all good, this is my media computer that Ive had attached to my TV now for a year. It was running fine 3 days ago before I got the great idea to convert it to Linux.
Now...once that fails I try to put in the burned DVD of version 9. Again the computer boots, I tell it to boot from the DVD...but this time the computer acts as if that drive doesn't even exist. It simply can't find the DVD drive anymore once I put a DVD into it. Is this a problem with the basic reading?? It'll read a CD but not a DVD. If I let it boot all the way to the live Ubuntu CD, the DVD drive is recognized just fine, reads DVDs, etc. Is there another solution, something I should be trying? I need this comp on Ubuntu. I've already converted all other systems in my house and this POS is the only abomination still using windows.

I have an odd problem with a copied DVD. I started with a commercial DVD and created an ISO file. The ISO file plays perfectly with VLC. I take the ISO file and burn it to a DVD+RDL without error. The burned DVD will not properly play on my computer or DVD player. It loads, but the menu is jerky and full of video block artifacts. The menu does not function properly. I tried this more than once with different software, including going directly to the DVD. I am using a drive that worked before, with the same stack of DVD+Rs that I used before.
Here is where it gets interesting: I can take the non-working burned DVD and copy it to a new ISO file. The new ISO file works fine with VLC. Obviously the data is getting properly copied from the source DVD, and it must be good on the burned DVD, but it won't play properly.

I burned these very important data files on the large DVD discs and now Ubuntu can no longer see them. It can only see the file folders but the files are still there. I took a bad screenshot with a camera but you can still see that the files are still there.

I checked the md5sum of the iso using winMd5Sum utility, it is OK.
To check the CD, right clicked the md5sum file in it, send to winmd5sum, and then copied the corresponding hash from the ubuntuhashes page into the bottom text box, and compared. The message box says md5 sums are different. Now the question is, have I done it correctly, I mean, is this the way to check a burned CD, OR, is there another way to check md5sum of a burned CD?

I am able to burn DVDs with either Brasero or k3b, but opensuse then cannot mount them .Those DVDs do contain the burned data since I can see it and read it on a Mac.Never had any problems reading other DVDs. This is the first time I burn my own DVDs. So is there something particular that I should do when burning in order to make them readable on Linux? What shall I check for? The error message mentions a 'wrong fs type'. I didn't format the DVDs before burning them - just used them as purchased - can that be a problem?

So I picked up a new (too me) laptop Dell Laditude C640, Tried to install Ubuntu 9.10 on it, won't boot, all bios setting correct. Couldn't figure it out. Went through my stack of distro CD's Oddly I found It WOULD boot FC12, and a Debian Lenny Netinst CD (But not the full install one). Even weirder. Assumed bad CD, re burnt with new;t DL'd iso, Nothing. Tried on different media, Nothing. Burned it on my GF's laptop (Win7) WORKED! WTF kind of crap is that? what can it be doing that K3b / Brasero isn't.

i was working in this Macbook (its my mothers i do not use apple very much), just looking at ..... and normal stuff. no installations or anything, only used my external harddrive. Next time i turned on my computer, this weird gray screen showed up with something written like "kernel mismatch from your hardware" or something like this, i panicked and didnt know what to do so i restarted like the message in multiple languages said so. Nothing happened.
I tried to boot from CD (press C key) and it worked so i went on disk utility and looked for errors but all says fine. I tried making a copy of the Macintosh HD to my external hard drive so that i could re install mac but after a while copying it stops and gives me an error saying "operation not supported". I asked a professional and he suggested using a live cd of Linux (ubuntu 9. ) to try and retrieve my files from there. I did this and the live cd worked and i could see into all my folders but when i went to /Users/myuser/ none of those folders would let me copy, open and see the files. Desktop is where the important data is. It gave an error file permissions. I cant compress, open, see the files nor copy them. This is very annoying as the files are extremely important and i cannot do anything to delete them.
500gb external hard drive
Macbook Pro
Linux Ubuntu
Apple Original Install DVD (Snow Leopard) way to retrieve these files and copy them onto something. I really need this with urgency.

I have heard great stuff about 10.04 so I am going to download and install it before the release IF it's ready though. So is there anything I should know about before I do this? Any bugs or things that hasn't been fixed yet?And beta 2 is that latest one right? And the last one before the final release?

After burning files to DVD+RW, the owner is changed to root, and all permissions are read only. I want to periodically open these files, update them, and save to the DVD again, but I no longer have permission and cannot change the permissions since I am no longer the owner. I tried sudo commands, but get responses "Read only file system". I have erased and reformatted the DVD and started over but get the same results.
I have Ubuntu 9.04, and have tried Brasero and Nautilus and get the same problem. Am I using the wrong kind of DVD/CD?

I'm looking for a small terminal tool to verify a burned disc and compare it to an iso file.
I googled for verify burned disc/dvd - no mateches.
There is a thread, which tells how to do it in k3Burn - but I need it on terminal to use it with ssh.
