If *just* the partition table is lost, but no damage inside the individual partitions, testdisk can easily reconstruct it but looking for superblocks (even w/ FAT).

I.E. no remaining filesystem is needed, it does exactly what you need (although filenames aren't preserved. I don't know about the other suggestions, so they might be worth trying first. Yes, photorec is an completely different thing. It scans through all blocks on disk and tries to find out what kind of files they might belong to. This way you can reconstruct a lot of files if you lost the fs' metadata (which can happen easily on FAT :(). But this is an heuristic, not an stable approach. So you have to look through all reconstructed files if they're really okay. If just the partition table is broken, you shouldn't play with this - use testdisk instead. cu -- - Enrico Weigelt== metux IT service - http://www.metux.de/ - Please visit the OpenSource QM Taskforce: http://wiki.metux.de/public/OpenSource_QM_Taskforce Patches / Fixes for a lot dozens of packages in dozens of versions: http://patches.metux.de/ - -- gentoo-user@lists.gentoo.org mailing list

I'm not guru at this :-\ Recovering will be really hard think, if you do not know the exact numbers there, it is probably impossible. But you may be lucky and nothing wrote to the data part. In that case, it should be relatively easy to save the first partition of the two. Grab fdisk (the unix one is probably better, it does exactly what you tell it to do and has better help) and create a single partition over the whole disk, then mount it read-only (so nothing can get corrupted, if you do something wrong). You should be able to get the data from there. I wish you luck -- When eating an elephant take one bite at a time. -- Gen. C. Abrams Michal 'vorner' Vaner pgpltrfDLJ9Ab.pgp Description: PGP signature

Re: [gentoo-user] HELP! partition table is corrupted
Couple of other questions and situation update: - there were not writes to the disk - this is good I think - the original disk division was 120GB (NTFS) and 40GB (FAT32) - the fat was the first one - and now the sizes are different (the first one around 30GB and the rest) - is the photorec able to search data in this partition table corruption level? - I'm going to buy ne disk and to make dd of the corrupted one Thanks a lot Pat On Sun, 23 Mar 2008 12:01:08 +0100, pat wrote Hello, My brother has a second disk where was two partitions formated as NTFS (the big one) and FAT32 (small one), but something brakes the partition table and now there are two linux partition tables +/- the size of the previous logical drives.

Liviu gparted is always the first choice in situations like these. The trick is to realize that if you recreate the partition table the way it was everything just comes back (assuming no destructive write to the drive meanwhile, like mkfs.ntfs...) so all one needs to know is where did the old partition end? gparted can go hunting through a disk looking for that info -- Alan McKinnon alan dot mckinnon at gmail dot com -- gentoo-user@lists.gentoo.org mailing list
