[net.micro.apple] Apple ][ Drive problem

A friend of mine and I have Apple ][+s.  He complained that his drives would
not read some of his disks.  He brought his drives and controller card over
and we experimented by mixing and matching cards and drives determining it was
his drives, not his card.

$200 later, with a swapped out drive, and a bit of tweaking on the other, he
has no problems.  He did find out, some way, that the disks he was unable to
read were Pascal format (he says.....)

Anyway, much to my horror and suprise, I now have the same symptoms.  Neither
drive will boot Pascal.  DOS 3.3 works fine.  With a pascal disk, the drive
seems to read a little of the disk, keeps spinning until reset is hit and
leaves a screenful of inverse @.

Does any of this sound familiar to anyone?  $200 is a bit hard to come by 
right now and I really need the system, so any information you could give
me (e-mail) would be appreciated.

There are several possible simple cures.  There is the drive speed
which you can tweek.  Some drives take a while to settle down.  The 
other more interesting problem is from magnetic fields in the area of the 
drive.  I find that many drives are position sensative with respect to 
the monitor.  Try running a loop and more the drive till you get no errors.

I saw this ad in a computer magazine for this company in Florida that would
repair Apple drives for $30 and IBM for $25...If you need to know the address
etc. mail me and I will look it up for you.
