There is a good chance it was the disks, not the drive, in this case.  The
media (coated polyester film, generally) of floppy disks has high thermal
and humidity expansion coefficients.  At high temmperatures, the data tracks
can move enough to be unreadable by the drive.

Good move.  I recently moved my Mac to my basement (oh, that's right, no
basements in super-state CA :-) ) because my upstairs was too hot for the
Mac's convection cooling to work well.  I'll have to move it back in the
winter for my own comfort, I suppose, but that's not a high price to pay
for the increased longevity (speaking statistically, of course.....).

Quality used to be free, but now it merely has a fantastic ROI.
