How large was your sample size to conclude the rev. T6 SFD-321B doesn't work with DD disks?
Because I received one the other day and — as far as I can tell — it works fine both reading and writing DD disks. Supercard software media test is successful with a DD disk and dumps made from Amiga disks seem fine.
My drive is a Compaq OEM model, SFD-321B/LCPN2

Unless your drive says "T6" somewhere, I believe it is a Rev. L drive.
Just now, I found some vital information regarding how to decode the packaging information on the Samsung SFD 321B drives: OEM MANUAL SFD-321B.
Please take a look at section 8. Packaging Description.
While the discussion so far has focused on revision identification, for example T1, T2 ~ T6, it could be important to decode the serial number as well to get the year and month of manufacturing.
The "LEB" part is apparently the buyer name. I have no idea to what extent buyers were able to affect choice of components so this might not be as important than noting year and month of the make.
I don't know if other production divisions followed the same guidelines though, since this manual is from SEMA Electronics, or if there were revisions to the manual itself and the production description over the years, but this document should give a good idea of how to decode the label description.
