Short answer, i don't think so.

I found a SCSI IBM "DGHS09Y  CLAR09" still formatted to 520 byte.
I've twiddled the code a bit so the output isn't identical to
previous FC runs. But my main goal is to show the format mode
page "Mask" isn't all zero's for this drive and blk512-linux.c
doesn't work for a "regular" SCSI drive either.

The DGHS09Y drive is behind 53c1030 (built-in) using mpt v2.03.00 driver.

thanks,
grant
