The original drive is 300 RPM. You can write floppies no problem for it with a standard non 3-mode PC floppy drive.

There are something wrong :
1942.D77 ,Albatross #001 (Disk 1).D77 and Alpha.D77 seems to be double sided/40 tracks floppy images. This is ok for a 5"1/4 disk, but not very compatible for a 3"1/2 disk drive....
am i missing something ?

No you are not missing anything. The FM-7 line originally used 5-1/4" drives, but moved to 3-1/2" drives later on. These images were originally for 5-1/4" disks but can be written to 3-1/2" disks using the utility DITT. I have written them to 3-1/2" disks successfully many times. Hope this helps.

So there are 40 track used over 80 used on 3-1/2" disks ? there are no double step used with 3-1/2" disks ?

To clarify (11 years after the question ;)), early FM-7 machines used 40 track 5.25“ drives. Then when Fujitsu introduced the FM-77 they switched to 40 track 3.5“ drives (YE-Data YD-625 for example). Lateron with FM-77AV20 and 40 they switched to 80 track 3.5“ drives. Those machines will double step the head if a 40 track formatted disk is detected.

To use HxC on models with 40 track drives you have to leave double step disabled during conversion as well as in the configuration. On models with 80 track drives you have to enable double step during conversion AND in the drive config. It will work like a charm then.
