Hi Philip,
Normally the data will be mapped to another partion of the disk and the
defective sectors will be added to the defective grow list.
You might take a look at 'man camcontrol' to get some more control
about your scsi devices, and to check those bad sector tables.
Be very carefull using that, though, inproper usage can destroy your
data.
Gr,
