Well, if you're suspecting calibration issues, you could try slightly adjusting the spindle position and/or speed of the motor until the disk could be properly dumped?

You have three adjustments: spindle alignment, read head position, and motor speed.

the guide for correctly aligning the spindle is here:

If you have a scope, you can use it to set the read head at a position where the signal is strongest using this guide:

you can also try doing this with a good digital caliper.

motor speed can be tuned with the copy master program:

I believe a speed of 4-5 should be optimal when a disk is inserted.

good luck. if you want to sell it afterwards, let me know.
