If it's like a TOSHIBA CD-ROM XM-3301TA (which is what I have) then
there's one or two tiny traces to cut, or jumper(s) to remove that'll
reduce the block size.

Somewhere there's an on-line FAQ answer or maybe even on-line manuals
from Toshiba for the drive....  Check the Sun Hardware Reference for
clues.  It seems to still be available here:
