Thinkpads have a variety of security options. Did you happen to use a hard disk password? It might be a good idea to run strings(1) on the block device and see if you recognise anything. Something like "strings /dev/whatever | grep ........................." should give you a good idea of whether encryption has been used. > Assuming that only the partition table has been corrupted (and this is > looking more and more hopeful rather than realistic) is there a way to > recreate it without destroying the data and leaving the file system intact? > When you create a boot disk (from a debian woody install) at installation > time, is it smart enough to save a copy of the partition table to this > disk? The first thing to do is to use dd(1) to copy the entire hard disk to another device. If your hard disk happens to be failing then you want to get the data before it disappears! I recommend doing this right now without any delay. Even if your hard disk is in perfect condition you still want a backup in case your attempts to recover data screw things up. Probably the best thing to do is to get another disk of similar size and try and use it for restoration. The first partition on a disk starts at a fixed offset. You can work out the size from looking at the ReiserFS superblock. Below is the file(1) data for checking for ReiserFS. If you have Reiser 3.6 (most likely) then at offset 0x10000 there will be a little-endian long specifying the size of the file system. Once you know this and the geometry of the original disk you should be able to work out where the next partition starts and repeat the process. 0x10034 string ReIsErFs ReiserFS V3.5 0x10034 string ReIsEr2Fs ReiserFS V3.6 >0x1002c leshort x block size %d >0x10032 leshort &2 (mounted or unclean) >0x10000 lelong x num blocks %d >0x10040 lelong 1 tea hash >0x10040 lelong 2 yura hash >0x10040 lelong 3 r5 hash -- http://www.coker.com.au/selinux/ My NSA Security Enhanced Linux packages http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/~russell/ My home page -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
