Re: [PATCH] scsi_lib.c: continue after MEDIUM_ERROR

Ric,
Both ATA (ATA8-ACS) and SCSI (SBC-3) have recently added
command support to flag a block as "uncorrectable". There
is no need to send bad "long" data to it and suppress the
disk's automatic re-allocation logic.

That'll be useful in a couple of years, once drives that have it
become more common.  For now, though, we're hacking current drives
using READ/WRITE LONG commands, with a corresponding patch to libata
to allow for the longer "sector size" involved.

Having real bad sectors, exactly where we want them on the media,
sure does make testing / fixing the EH mechanisms a lot more feasible.

Cheers
