I'd forgotten about the Plextors.

All the newer Toshibas -- and most other SCSI-2 CD-ROMs -- will accept the
appropriate MODE SELECT command. The 3201, 3301, and 3401 all have
internal jumper pads to hardwire the block size. I think the 5401 does as
well. The 3601 and later don't (the pads are there, but they don't set the
block size).
