Run the media test. When it fails, click the IGNORE option and let it finish. Then, make an image of the disk you ran the media test on (index mode is fine). Send me the image (data@cbmstuff.com) and I can look at it. You can load the image into the editor/analyzer, read a track and click on the Display Flux button. You should see a thin straight line at the 8us point, with no stray dots anywhere. If you don't see that, then you definitely have a problem with the media and/or the drive.
I see about 2 good 3.5" disks out of every brand new 10 pack. Typically with 3.5" disks, it's the last 4-5 tracks that fail. I have yet to see a 5.25" disk fail. In fact, I had to destroy a 5.25" disk to make sure the media test was actually working on 5.25" disks.
