Well, Allison, you're memory's getting to be like mine. I've got three of
the 2266's and they all seem to agree they're about 1GB in capacity.
BTW, the drives don't seem to have a problem with the SCSI-1/SCSI-2 thing,
but the software, often written the way it is because the authors weren't
born before SCSI-2, don't realize that they get the same effect using the
SCSI-1 command set. As stupidly as SCSI is used on PC's, no overlapped
seeks, no command queuing, no disconnect, little use of synchronous mode,
they're not even getting SCSI-1 performance.
