Thank you very much for that hint. It's documented in 'man reiserfsck', but I've overlooked it. I've tried --rebuild-sb but it reported that it couldn't find the journal. Then I've done reiserfstune --make-journal-standard and also experimented with --no-journal-available in various combinations with --rebuild-sb and --rebuild-tree but I've had no success. Thank you very much for your quick reply. I've never had a single problem I could blame reiserfs for, the only partition under Linux I've lost so far was an ext2. But I've the feeling that e2fsck is much simpler: Just execute it and answer everything with "yes", you don't understand it anyway. Then your filesystem is either gone or still there and you can look in lost+found for important data. No need to experiment with --do-this-and-that --without-doing-that.
