Start with STAT DSK:  on the CP/M machine
That will give you some of what you need.
Examining sector contents is needed to determine sector sequence, 
interleave, skew, and "side pattern".
Then, of course, there are surprisingly many other oddball weirdities, 
such as inverted bits, altered/non-standard/invalid sector headers, etc.


But, if the machine is still functional, you can transfer everything to 
SSSD "CP/M Standard", which is widely supported.
