Hi all.  I have a firewire hdd which has some bad blocks.  Trying to run
badblocks(8) directly is very frustrating, because each time it encounters
blocks which are bad, sbp2 does something akin to the following:

Oct 18 00:25:10 cpp kernel: end_request: I/O error, dev sda, sector 14346912

After this occurs, I have to either unplug and replug the drive, or rmmod and
modprobe sbp2 (in addition to doing ^C on badblocks while it's in the D wait
state so that it doesn't detect all subsequent blocks as being bad).  Is there
any way to make this process less painful than it already is? TIA.
