Josh, I have never been able to either. And
it's not the SD
start up. It may be the lnterleave ??? or something they did that was
odd. I have been making copies on running Altos machines. My 8"
system is like yours and seems to like everything except theses.
It is NOT the interleave. What they did that was odd was 128 byte MFM
sectors.
Chuck is correct. He KNOWS what he is talking about.
MOST 765 based FDC chips can not handle 128 byte MFM sectors.
SOME can.
Fortunately, there are VERY few disk formats that use 128 byte MFM
sectors. XenoCopy did not include any of them, because of the FDC
problem.
