Almost any Plextor CD-ROM drive will have a jumper
that will enable it to
be used on a host expecting 512k blocks.
I'd forgotten about the Plextors.
I understand that many newer Toshiba CD-ROMs will also
work equally well
with 512k or 2048k blocks. As far as I'm aware, of the older Toshiba
CD-ROM drives only the 3201B (3401B? I forget) is modifiable.
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).
