 high-volume items, but for the low-volume Sam market, it would have been
 perfectly do-able :)

It doesn't seem a good idea because if they are that crappy then
who's to say they won't start losing real data?  (I suppose there
might be a market for time-limited software...)

Better to buy good disks and scratch them with a pin, or something.

Wouldn't this be defeated by write-protecting the disk?
