- It isn't likely because if a drive does not support synchronous transfer
- it either does not identify itself as supporting the SCSI message system
- or it does and negotiates asynchronous transfer. The latter can be done
- by rejecting the request or by negotiating an offset value of zero.

- It may.. if it is broken. But that's not likely.

-
- Fortunately we do not need "full compliance". Synchronous transfer is a
- very old thing and most SCSI devices have no problems with it.
-
- But then you might have to turn off synchronous mode more often
- because you use lousy cables.
