< * Dysan 3740/2D, Double sided, Double density, format:
< 128 bytes/26 sectors, index 1 & 2. (I don't know if these are hard
< sectored. There is just one index hole in the disk but two index
< holes in the jacket)

These are flippies, you turn the over to use the other side. Hence two
index openings.

< * Memorex 3201-3015, Compatibility: Shugart, Write protect,
< Single sided, Single density, Sectoring: 32 hard
< (Just regular 32 sector hard sectored disks)

Exactly.


< * Memorex 3071-2003, Single sided, Single density, Sectoring: hard
< * Verbatim FD 65-9000-HR, Single side, Single density, Vydec/
< Memorex compatible.
< (These have 33 index holes in the disk, but they are
< arranged around the out side edge of the disk. Also there is
< a 1 1/2" x 1/2" notch cut out one of the corners of the jacket.)

old style hardsector Ony a few drives used that style.
