    We have been seeing an unusual problem with our Atari 520ST lately that
 someone may know about.  Our 520ST has been upgraded by the dealer to
 1 Mb and TOS in ROM.  We also have a double sided disk drive rather than
 the standard single sided drive.

    For certain disks, the console appears to reset itself while reading a
 disk.  This reset is equivalent to manually depressing the reset button on the
 back of the console (i.e., the monitor blinks and the disk drive begins
 reading the disk again).  I have not yet established any pattern to this
 problem.  It happens on some copy protected game disks and on disks with TOS
 files (e.g., the TOS disk).  This problem is intermittent, and since it
 doesn't happen consistently, I suspect the problem is mechanical (disk drive
 timing, crossed wiring in the console).  How could poor drive timing cause the
 console to reset itself?

    Any suggestions?  Email would be appreciated.  Thank you.
