[Coco] Diskette Flipping Question

[Retro Canada]

Hi,

I just got a 36-3029 drive unit using it with a FD-500 interface in my
Coco3. It works nice, but I noticed that I cannot flip the disk to use
the other side, since this drive is single sided. What is the problem
? Do I need to make another alignment hole on it ?

The apple //c and C-64 don't have this problem I can flip and use both
sides with no problem.

Thanks,
