I keep on getting this error on my A: drive:
Invalid disk change,  Abort, Retry, Fail?

I remember reading somewhere that it is caused by a bug in IBM's 
PC-DOS.  Sometimes it doesn't register a disk change and it chokes
when you change the disk in drive A: 

The only way that I can use drive A: again when this happens, is to
restart the machine.  Real irritating.

Is there a bug fix out there somewhere to fix this thing?
Or someway to get the machine to recognize the new disk, without 
restarting the machine?
Please e-mail your messgaes and I will summarise a response for the 
net.
Thanks.
