Yes. You should see how it handles a SCSI disk error!

A media error when running `badblocks` on Linux Version 2.6.0 results
in the same misbehavior with a BusLogic controller.

I tried to boot, it came up but encountered some kind of disk
error. I tried to run `badblocks` on an unmounted partition
that reported zillions of errors during the normal e2fsck check
upon startup.

I booted several times with `init=/bin/bash`. Most times it would
panic with 'trying to kill init' errors. One time I was able to
get it up and I attempted to run badblocks. --Impossible... It
thinks everything is bad and badblocks doesn't help by re-reading
bad blocks. The SCSI system takes 1 minute to reset after a bad
block. I gave up around noon after trying since 8:00 in the AM.
Because of the re-read by badblocks, it's possible that there
may be only one bad block that it never gets past!

With 2.4.20, badblocks reports no errors and e2fsck was able to
rebuild all partitions trashed by version 2.6.0.

If anybody has a Buslogic driver fix, I'll be happy to try it.
