Well, head cleaning is good advice, but the kits are another story.  I've had
disk failures occur suddenly, at which time I've used a kit to clean the head.
No dice.  Then, immediately, I've torn apart the disk drive and cleaned the
head directly with a cotton swab and Freon TF (I assume alcohol would also
work).  Presto - working disk.

The point is that THE KIT FAILED TO CLEAN THE HEAD!  This occured more than
once, so I've never bought another kit.  It is possible that cleaning kits will
work but only as preventative maintenance, I don't know.

Chuq is definitely right about keeping those heads clean!

For net info, the kit I used was made by Check-Mate Computer Suplies Inc.,
Randolph, MA.  It's a clever kit, it will handle single or dual-sided drives,
it just doesn't work!
