I have been having disk access errors recently with disks that checked
out okay with disk verifying programs.  I took this disk and my 1040ST
to my local maintenance guy.  After doing some tests, he concluded that
I should stop using my brand of SS disks.

He said many SS disks are verified for the Mac drives which have the
heads on the opposite side as ST's drives.  He once tested 100 SS
disks, reading, writing, formatting repeatedly.  He determined that 
about _20_ of them developed seriously bad data corruptions.

He recommends Sony SS disks, because he says they are verified on both
sides, so that they can be used as SS disks on either Mac or ST or
what-have-you drives.  So I am going to trade my disks to someone
with a Mac.
