If is really is a 3401, look at the circuit board that pokes out of the rear of the drive near the scsi connector.  It has two solder blob looking thingies that actually look like:

	(|-|)    (|-|)

To clarify, these are two solder patches with small traces between them.  If these traces hace not been cut, the the drive is set up for 2048 block size.

Consult the Sun CDROM FAQ (off of sunhelp.org) to confirm all of this, but cutting the traces should fix your problem.  It may also make the drive unusable for a PC, so consider carefully before doing anything irreversable.

ALso, I've had great luck with Plextors.  A bonus for them is that they use a jumper to control this behavior, and they are relatively cheap in the older slower variations.
