When its finished, I couldn't mount the partition. I've got error messages I tried --rebuild-tree linux:~ # /usr/local/sbin/reiserfsck --rebuild-tree /dev/hda1 reiserfsck 3.6.11 (2003 www.namesys.com) ************************************************************* ** Do not run the program with --rebuild-tree unless ** ** something is broken and MAKE A BACKUP before using it. ** ** If you have bad sectors on a drive it is usually a bad ** ** idea to continue using it.

If you are sure that you had the reiserfs on this partition, then the start of the partition might be changed or all data were wiped out. The start of the partition may get changed by a partitioner if you have used one. Then you probably rebuilt the superblock as there was no one. Zero the block at 64K offset from the start of the partition (a new super block you have just built) and try to move the start of the partition a few cylinders aside and check if debugreiserfs /dev/xxx detects a reiserfs super block. If it does this is likely to be the right super block version. If this makes you nervous, try www.namesys.com/support.html, and for $25 the author of fsck, or a colleague if he is out, will step you through it all.
