[comp.sys.mac] Diagnosing disk drive problems and Cleaning

EUA@PSUVM.BITNET (Mel DeYoung) (01/05/89)

   After using around 70 Macs for over a year and recently
experiencing some odd problems not caused by viruses, the
English Department at PSU is thinking about starting a
periodic cleaning and diagnostic program for our Mac disk
drives.  Is there good disk diagnosis software?  Is drive
cleaning worth the effort?
