   You can't judge a disk by it's color.  But you can often judge a disk
by the look and feel of it's shell.  One the back of the disk, near the
write-protect slider, there is a small lozenge shaped depression.
You will find either "JAPAN", "USA", or nothing in this area.
This tells you where the shell was made.  Nothing usually means USA.
We have found that many of the "USA" or "nothing" shells have occasional
problems seating in the drives.  And an "occasional problem" is all you
need to trash a disk.  The root block gets written out a bit off-kilter
and becomes unreadable when the disk is seated properly.  Most of the
"JAPAN" disks that we get have shells that feel sturdy and thick, and
they generally seat very solidly in the drive.  

   I've had black, and tan, and blue "JAPAN" disks and I've never had
to throw one out.  I've had blue and maroon "nothing" disks and have
flung several of these in the trash when they suddenly decided they
were Not DOS Disks.
