Most such programs are for the purpose of transferring the contents of a
FILE from one disk format to another. SOME also include the capability of
duplicating a disk, but often ONLY IF the system tracks use a similar
physical format to what is used in the data are (no single density boot
tracks, etc.)
Instead of looking at file transfer disk format conversion products, there
are a few that may be better suited for you.
Look at Teledisk.
Look at CopyII-PC (and at the "Option Board"), and at the "CatWeasel".
Although most commonly used for unauthorized duplication of
copy-protected disks, it will duplicate many of the disk formats that are
physically possible.
Be aware that SOME disk formats, including a few hundred of the CP/M
formats, are physically impossible to read/write/duplicate using stock PC
hardware. The stock PC hardware can only do MFM with WD style sector
headers. Some formats, such as hard-sectored and GCR can NOT be done
without other hardware. Some other formats, such as FM ("Single Density")
or some invalid headers (such as Kaypro DS), can be done with some FDC's,
with some additional software.
WHAT CP/M format are you trying to do?
