    WRITE(6) 2 blocks to 012be8 failed on the second block because of:
        03     - unrecoverable media error
        10 00  - ID CRC OR ECC ERROR

    Any decent OS should have been able to recover from such an error,
    and it looks like 2.3.2 did just that.  Just in case, I would suggest 
    calling their customer service and asking them how their OS handles
    badspots on a disk.
