    Using 'init .21 -1' under Davex with an Apple 3.5 inch drive
resulted in a disk that was formatted on both sides.  I verified this
by first formatting a 3.5 inch disk via MS/DOS.  That gave the disk a
capacity of 720K via 9 512 byte sectors per track on both sides of 80
tracks.  I then transferred the disk to a IIgs and formatted it via
Davex using the command 'init .21 -1'.  I then took the disk back to
the MS/DOS system and tried reading the second side of the disk with
the sector editor available in PCTools.  No go, ergo, the IIgs
formatted both sides.

    I was able to convert the MFS disks to HFS disks via the AMax Mac
emulator running on an Amiga 3000.  I also discovered that the disk
drive in a Mac SE, given to me, doesn't work.
