The only gotcha is that the track numbers run from 0 on the D9060/D9090 and 1 on the floppy drives. >> >> > It should not be too hard to modify cbmconvert to support D9090 >> > images.

I'm not yet familiar with the detailed internals for the HD's but yes, I think so. As I said above the tracks go from 0-152 and the sector numbers run from 0-127 on the D9060 and 0-195 on the D9090. >> >> Rob >> >> Message was sent through the cbm-hackers mailing list > > > > Message was sent through the cbm-hackers mailing list Message was sent through the cbm-hackers mailing listReceived on 2014-01-27 13:01:06
