[net.micro.mac] disk problem

goran@erix.UUCP (Goeran Baage) (12/02/85)

Today the contents of 6 out of approx. 30 disks mysteriously
disappeared. All disks were stored in the the same diskette tray.
Inspection of the disks with FEdit reveals that there is nothing
but zeroes on the disks (that's what FEdit says, anyway; OK, OK, I
didn't read all sectors, but all I read were zeroed).
Could this be the result of an external magnetic field? It seems 
strange to me that some disks are OK and others all zeroed. 

Has anyone out there had a similar experience? WHAT HAPPENED?????
