   My dual drive A2000 exhibited similar symptoms recently. I noticed
that sometimes when booting up, a requestor would pop up saying
that the "disk had a read/write error".   Additionally, I was unable to
use the MessyDOS, the transformer, and several heavy-protected software
when using this particular drive (DF0:). If I used DF1: everything
would run smoothly.
   I disassembled DF0: and found the problem.  There was some lint
at the end of the read/write head's stepping motor shaft.  The lint
would prevent the read/write head to fully align with track 0.
   Carefully, I removed all of the lint, and reassembled the drive.
It has been working flawlessly ever since.
