[Coco] Re: [Color Computer] Copy protection

Tue Jun 1 16:39:55 EDT 2004

What I've found recently is that Anadisk reads the old coco formatted disks fine, but 
when it comes to writing the old format on a new disk, there is a dependance on the 
actual floppy drive.

When I've tried to replicate disks using an IBM 360K drive, I had problems every time.  
the disks were unusable, and when examined in detail, the final sector in the cylinder 
was corrupted.

I've since mounted an actual Tandy 180K floppy drive in my PC to overcome this.  I use a 
drive that shipped with my coco FD-501.  That seems to work correctly and so far, every 
time.
