Summary: External disc drive problems


I had a problem with bad disks too.  One day I kept getting "This is
not a Macintosh Disc, reinitialize?" query to a bunch of discs.
Reintialization would always fail.  At first I thought it was all
the discs made by a certain company that were bad because all of all
that company's discs went bad, while all of those of other companys
remain good as I tested them.  So I threw out all the bad discs.
Then stupid me realized that it was not the companys fault it was
just that all the discs that were being placed in the external drive
were failing; it was just an incredible coincidence that I place all
of that particular company's discs in the external drive.

Well I took the external drive to my friendly neighborhood Apple
dealer and was given an estimate of about $112 for the minimum labor
charge of one hour and the cost of replacing the sony drive with in the
external disc drive.  It turned out that the Sony drive was
faultless; the problem was in the cable that connected the drive to
the Mac.  I ended up paying ten dollars more than the estimate
because the PART COST FOR THE CABLE IS TEN DOLLARS MORE THAN THE
PART COST OF THE SONY DRIVE.  I was absolutely stunned when the
dealer explained that to me.  Other than that experience I have
never had a problem with a blank floppy disc that I bought failing
for a reason other than negligence.  (You see I have a sister who
likes to use my discs as coasters.  My neglience is not connecting
my sister to one end of a high voltage power supply.)
