The IBM PC and Commodore use totally different disk formats (MFM and GRC respecitively). PC drives use the index hole, Commodore drives don't. For this reason it would be unlikely that you could ever read in CBM disk on a PC. However Commodore created the 1571 which has the ability to read both types of disk formats, so the reverse could be done, ie. reading a PC disk on a Commodore. There is programme called "Big Blue Reader" for the 128 that will let you do this. >I hope someone will provide the answer to this since I have often wanted to >read disks formated on my IBM PC-AT on my 1571 drive, but have been >unsuccessful.

I have heard that disks formatted on the >AT cannot be read by the 1571 no matter how they are formatted, is this >correct? > IBM AT format disks put more on a disk than IBM PC disks (either by using 96 tpi or quadruple density I'm not sure), and the 1571 can't read these high capacity disks. However if you format and create 360k (IBM PC) format disk on your IBM PC you can use Big Blue Reader to read that disk. -- l/ {uunet!mnetor!lsuc,utgpu}!ncrcan!ziebmef!ross // [OO] or just call me Ross for short...
