crashed partition table & lost reiser
Hi all, I've had a partition table crash... but thx to gpart I'v got the 3 primary partitions back. hda2 is an extended partition wich contains a swap partition and a reiserfs partition. gpart also found the swap, but didn't find the reiser. I tried approximately every option for gpart, without any succes thus far. I also tried some reiserfs tools on hda2, hoping one of them would be able to find some-thing, any-thing that resembles parts of the reiserfs. No succes. It came back with the respons it couldn't read the block. I understand it's reaction, because i ask it to check a partition (hda2) that hasn't got a filesystem. what i do know is approximately the place where the partition should start, and so where the filesystem should be found. What i would like to know is wether there is some way to scan that area form the disc, en find some indication from the reiserfs. Because I approximately know the place where it should start, i tried to define the logical partition overthere. I did two attempts, then stopped because i suddenly realized that i was not poking in my normal partition table, but that i might be poking in data blocks, when i tried wrong sector numbers. any tips are very welcome. Thanx in advance! Pieter

Oh, my... I hate that. You should have a printed copy.
gpart also found the swap, but didn't find the reiser. I tried
Then the start of the reiserfs should be exactly at the end of the swap. You make me wonder if gpart can guess reiserfs parts, or if yours was broken somewhere in the process, or previously. I could try... Hold on [...] Ok, I did a trial run in my first disk. It says my hda3 is ext2, when it is reiserfs. gpart: Primary partition(3) type: 131(0x83)(Linux ext2 filesystem) size: 2055mb #s(4209024) s(106510950-110719973) chs: (1023/254/63)-(1023/254/63)d (6630/0/1)-(6891/254/57)r Real (fdisk): /dev/hda3 6631 6892 2104515 83 Linux Notice the offset by 1 cylinder: gpart is "0" based, I suppose. Did you do this correctly on your system? It confuses things. An that is for the primary partitions. My logical partitions are incompletely detected - but here the types seem correct: Possible extended partition at offset(22003mb) ... Possible partition(Linux swap), size(1027mb), offset(46124mb) Possible partition(Reiser filesystem), size(3051mb), offset(48955mb) Possible partition(Reiser filesystem), size(2055mb), offset(52007mb) Possible partition(Reiser filesystem), size(3176mb), offset(54062mb) But no tracks numbers for the extended partitions :-( -- Cheers, Carlos Robinson
