No. Reiser does not handle bad-blocks. Ext2/3 does, but that doesn't
mean anything, because you shouldn't get them in the first place. Modern
HDD remap bad blocks internally, so if you see hard read error's like
your seeing, your best bet is to get a new Hard Drive.
This has happened to me, and I moved the filesystem to a new HDD, and
re-formatted the dodgy drive with ext3 with a complete bad-block scan
during the format. I now use this space as spare non-critical space.
Lots of rubbish and downloads, and iso images (of cd's I have), and
backups of data etc. I am fully expecting the HDD to start smoking any
day and for me to loose all my data (which doesn't matter anyway). But
so far its been turning for nigh on 6 months now without a blip.
The important thing though, is *dont trust it*.
Kind Regards
