If the drive speed was really 200 _RPM_ any disk would be completly
unreadable! I don't think even a broken drive is capable of 200 rpm.

It wasn't clearly stated by the original poster, but my bet is that
drive speed was checked with Copy II+. Copy II+ reports drive speed in
milliseconds, not rpm. 200 ms = 300 rpm. The drive speeds quoted above
are well within tolerance. Both of mine are set a touch on the slow
side (200.0 to 201.0 ms). Remember more time = slower speed!

As far as the read errors, drive speed is not the problem (unless of
course they were written on another system that was way off on it's 
drive speed). How long since you cleaned your read/write heads?
