Kinda interesting.This describes marking sectors as bad in an interleaved fashion so it might work on C64 and MS-Dos... fat 12 floppies ?Question is... does it actually work ?Makes me wish I still had a C64 to try it out ! :)Anyway how much thruth is there in this story...I think C64 floppies worked by burning something onto it... while PC floppies work with magnetic stuff ?Or am I mistaken in that part ? ;)Or is this just a software only trick ? Hmm...Bye, Skybuck.

I am not sure what kind of technology these C64 1541 drives used but here is something interesting in this article:It mentions how the upper tracks were not used because they were less reliable !I think the same can be said for some... if not all CD-Media... where the upper tracks seem to be of much less quality !Be it media quality or burning quality !Wow this could actually mean the C64 Disks were more reliable than todays cd/dvd crap ! LOL.Will we all be using C64 disks in the future ! LOL ;)Bye, Skybuck.

Reading/writing floppies for C64 and MS-Dos ???

Then you must really love the gross simpletons that infect USENET. You even have a pet name for them! ;-)

Yea, but... the FDC emulation in the ASICs of modern PCs (read: virtually all Pentiums) does NOT suport deleted data records. Now you can write the software for reading and/or writing deleted records, but these FDCs simply do not support the commands and nothing seems to happen. I used to write "copy protection" software where data and programs were in the FAT and directory, used deleted records, and records with absurd track/sector numbers - so i might know a little about such things.

Absolutely NOT! THe Commodore with the "magic" drive could read and write BOTH FORMATS because the drive itself had BOTH FDCs, programmable by the main computer (count: ONE).

Only the 1571 (360 kB, 5.25") & 1581 (720 kB, 3.5") drives could read or write to IBM formatted disks.
