@amiga1260:
My A4000 diskdrive wouldnt work reliably. I tried cleaning it, but that didnt help - not strange though as it wasnt dirty at all. I tried make it work giving it some exercise with formatting and writing as much as possible to disks. The formatting almost always worked, but writing real data to the disk was the big problem, it would work to fill up half a disk but then it was stop. With this as background I figured that the diskdrive could read/write zeros (formatting), but had problems reading/writing ones which exists quite a lot in real data
.
Anyhow, got the idea to exercise the drive writing only ones to disks without verifying, so I created an file of ADF-Size only containing ones and wrote that to the disk a couple of times and to my surprise the drive started working better!? Now, after some more exercise writing ADF-Images containing both only zeros and only ones written with both no-verify and verify, the drive works perfectly, so why not try this out as a last resort
.
Good luck!
