OK: I have C1581 formatted disks. When I use the TrackRead option in RawCopy 1.3g it reads in a track (hence, the name:). If I then go to the buffer and examine the track, I see raw-mfm data. If I select Decode MFM, I still get a bunch of garbage. If I select IBM Decode, then I get the actual data decoded. I know this because I am reading track 39 and after MFM and IBM decoding, it resembles the earlier commodore dir track formats. All I would like to know is: What Algorithm is used by the IBM Decode option? Another Question: Can I use TD_RAWREAD to read in a foreign formatted track? I am trying to write a prog to read and decode the 1581 tracks so that I can transfer the files over to the amiga (I no longer have a 1581, so 64 emul's won't help.) Thanx agen Jeff M.
