First, I probably deserve this for not having a backup.
My system was installed with Debian and Mint11. I recently installed Mint12 to play with. I expected all three to continue to work. I can no longer enter Mint11. I get an error saying it can't identify the specified partition. I think the cause is because in the fstab file I specified the id of the swap partition since mint11 had a tendancy to "change" drive designations. It's related to this question: Linux Mint: drives' map changing at reboot brings fstab error
Now Disk utility doesn't recognize the partition Mint11 is installed on. It simply shows it as "Unknown". The drive is a raid5 on a dedicated controller.
fdisk -l gives:
Disk /dev/sdc: 240.0 GB, 239997026304 bytes 255 heads, 63 sectors/track, 29177 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0000a3c7 Device Boot Start End Blocks Id System /dev/sdc1 1 24002 192794784 83 Linux /dev/sdc2 24263 29178 39480321 5 Extended /dev/sdc3 24003 24263 2093056 82 Linux swap / Solaris /dev/sdc5 24263 28656 35288064 83 Linux /dev/sdc6 28657 29178 4191232 82 Linux swap / Solaris
/dev/sdc1 is the primary mint11 partition.
Is there a way to access or recover the data on that partition? I can live with not being able to boot to it so long as I can access the information on it.
Thanks. Let me know if you need any further information.
--update-- I tried using testdisk to recover the lost partitions but it said the partition could not be recovered. The exact error is:
The harddisk (248GB /223 Gib) seems too small! (< 315GB / 294 Gib)
Check the harddisk size: HD jumpers settigns, Bios detection...
Before I do anything else, I'm running gddrescue:
ddrescue -vr /dev/sda1 /media/Backup/recovered_data_blocks.img gddrescue.log
This will give me a backup of the partition in case I mess up the actual one.
I've also used Photorec to recover all the files on the partition. However that basically takes all the files and places them in arbitrary folders with arbitrary names. I'll be able to find some critical files but without structure or names much will be lost.
At this point, I think I'm out of options. Does anyone have any other ideas?
I hate bitter sweet irony, I know better then to allow myself to be in this position!
