[comp.sys.atari.st] Single-sided drive problems

markez@csd4.csd.uwm.edu (Mark R Zbikowski) (02/17/90)

My drive is having difficulty reading bought (or rented) programs.  I
also have problems when I swap disks with other people.  They don't
always like to work.  Sometimes I get a directory, but it looks
completely mangled.  I have a drive speed tester, and the speed is
right on 300.  I opened up my drive to see if there was anything else
wrong with it (well, curiosity mostly drove me to that).  Does anyone
know what could be wrong?  Also, there are two pots (or variable caps)
on the top of metal case housing the drive.  Which is drive speed and
what does the other one do?

Have you used a FRESH disk cleaner for your disk head?
This helps me.  Try talking to some IBM PC repair people (after all where
would you fine an ST repair person) about changing the pots on the drives.
This might not be a good idea.
