	My IBM-PC is having the following problem. After working
merrily away for an hour or so, the time comes to save the work
on a disk. The save command is given and the drive A ( this is
a one drive system) LED comes on and the computer goes out to
a PARITY CHECK 1 error, thus locking up the world and losing
a great deal of work.
	Note the error is intermittent, about 50% of the time,
and it occurs on three different software packages.
	I've run diagnostics over night and find no errors.
I've taken the computer to the local computer store selling 
and servicing IBM equipment, they have cleaned and realigned the
head, they also have found no problem after 24 hours of testing
on the "ADVANCED" diagnostics.
	Yet the problem remains, asking the machine to write to
the disk is like flipping coins, half the time I win.

	Any ideas on where the problem is?
