There can be a problem with number of blocks. reiserfsck --build-sb will ask for that, I think. You should be able to calculate number of blocks in broken filesystem with mkreiserfs /dev/bad-partition. It will report you something like Count of blocks on the device: 4096560 among other lines and ask to continue. DO NOT LET IT TO CONTINUE. Use this block number in answers to reiserfsck --build-sb. > reiserfsck --rebuild-tree /dev/good-partition > > If this helps you - you may take a look at namesys.com/support.html > >
