[Coco] Y2k bug

The biggest problem I had with the ST-225 drives was the lack of a auto park
on powerdown.  The heads would usually come to rest on the directory track
and ANY movement would crash the drive.  The majority of MFM and RLL drives
made after them did auto park on power down and were much more reliable.

3.5" drives work O.K., IF you can find 720K disks.  My experence is that the
1.44 disks are unreliable for CoCo use.
