Problem with Commodore disks

[Draven]

Good question.  Run the media test in the Disk Utilities Menu.  That will read/write to a disk and test the drive and SCP hardware.   It could be something as simple as your disk drive heads are dirty.

You can make an image file (.scp) of a disk using INDEX mode and send it to me (data @ cbmstuff.com).  I can look at the image file and tell you what is wrong.

OK, I will do that and send you an image.
Thank you.
