Archiving CP/M 2.2 Source Code Programs to a PC (Fat or NTFS media)

Hi Fred, Thanks for the reply. The 8" SD diskettes are standard IBM format (I believe 3740 physical format) 26 sectors. I believe the 8" DD follows the same 3740 physical format but has 1024 byte sectors and that they could vary as to either 8 or 9 sectors/track. Regarding the 5.25" HD diskettes. I believe they are duplicates of the 8"DD just using the smaller media. The hardware is custom so there is no unique base of users or other software to leverage. There are two different platforms, both Z80 one platform uses the Western Digital 1771 floppy controller, the second platform was newer at the time and is Z80 with WD 1791 floppy controller.

Are the "8" SD" standard 8" SSSD? What format are the 8" DD? What format are the 5.25" HD? Are you SURE that they are HD? What make and model? There are approximately 2500 mutually incompatible CP/M disk formats.
