  I would put the disks in another, known-good system, one at a time, and
run badblocks(8) manually, so you can see the output.  Run it like this:

  ***** WARNING: The following command will DESTROY DATA! *****

	badblocks -v -w /dev/hdb

  ***** WARNING: The preceding command will DESTROY DATA! *****

  Change "/dev/hdb" to whatever the disk really is.  The "-v" switch runs it
in verbose mode; the "-w" switch runs it in destructive write mode.  It will
take awhile, but it should show you which disk is bad.

  Be aware that many disks drives will lock up and hang the IDE bus when
they encounter an unrecoverable error.  That will typically hang the rest of
the system too, so don't do this on a system doing anything important.  :)

  If both disks pass, chances are, something is goofy in the original
system.  Yell if that's the case.
