Well no-one has answered, so I had better!
The 3345 was really a 3350 that was re-partitioned so that each
3350 spindle looked like four 3340-70MB spindles/disks. It was a cheaper
way of getting (maybe?slower) 3340s if you could not handle the 3350
architecture yet. ( you got a faster
multiple exposure was somehow competition) ... which shot done my
3350 multiple exposure change. Then VULCAN was killed w/o even being
announced.

If you poke around a little you can get the Archives Index of

3375 was a CKD device and 3370 was a FBA device.

That was a long time ago and my memory is getting fuzzy...
I never used them.
That's why I asked.
I've only used (E)CKD devices.

No, the 3370 was FBA, and the 3375 was CKD, MVS only supported the 3375.

Rick,
I think we supported 3370 but not 3375 (which I think was the FBA device).
Back in those days, every time a new DASD device came around we had to do
device support in lots of different places because each device had different
geometry.
3370 is a FBA DASD (that's the one which had
