hi friends,

I had a very nice external usb disk; yesterday when I was trying to mount it, I didn't see it on file manager; so I tried to see it with partition manager, I saw the disk but it explained "no file system"!!!
any idea about what is happened and the right way to recovery a lot of important stuff I have there?
thanks a lot and happy New Year all

i would look into testdisk from a live-cd. be sure to read up on it before giving it a go at: http://www.cgsecurity.org/wiki/TestDisk
testfisk itself is already installed.my guess is, your partition table is broken and that should be fixable. as i dont know what happened, i cannot really advise you to try and fix the partition table or to first try to save the data with the integrated tool photorec. good luck.

Hi,

when using a recovery tool like testdisk it is allways a good idea to make a complete copy of the disk to a free or new disk first, using
      Code:
dd if=/dev/sdX of=/dev/sdY

and then working on the copy only. sdX is to be changed to the device ID of the failed HD, sdY to the ID of the new one. You may get the device ID's by fdisk -l.
One may also copy to a free partition of another disk and working on this copy after.

greets
ayla

I think I used some Hiren's cd. It helped to restore partition tables and data.

Had pressed the wrong key for the first partition (Windows, C-drive), could not recover from that one,
but I always keep data in separate partitions.

I tried with testdisk and with photorec with no result (?!).
it didn't find anything, I don't understand what's happened.
well, now the partition in which I have aptosid is full, so X doesn't start; I have about 2 GB more; I think it could be some log of photorec (stopped by default of electrical network), but I don't see anything, found by date with no result; where I can find?
thanks

the only two files bigger than 1GB are

/var/log/kern.log
/var/log/messages

may I delete them?

well, they should not be that big. so i would try to move them someplace to look at them. they might give a clue to what happened in the first place. both files together have =< 20kb here! the size they have for you means either, logrotate does not work, or logrotate works but some problem is spamming both files massively.
other than that they can be deleted, yes.
