Hi
I got an old Amiga 1200 working on WorkBench 3.2. but when I insert a disk in the external disk drive (DF1) it says DF1:

? and I can't open it by clicking the icon.
I was also wondering when a disk encounters a 'checksum error' whether it is broken or recoverable. Since I got this ami-pc link disk I never used before and it encounters read errors.
These are probably simple matters but I was never familiar with Amiga. So anyone can help me out?
Cheers
