A MEDIUM ERROR is generally a bad thing. For a brand new disk, you shoudlre
turn it and get a pristine replacement. The ASC=11 ASCQ= 0 indicates an
UNRECOVERED READ ERROR. While one can attempt to reassign the individual
blocks, I recommend backing up the entire disk, and then using your host
adapter's utilities to re-format and verify the disk. Running scsiinfo before
and after to look at the bad blocks table is also a good idea.
