During the 1980s I was involved with one minicomputer installation
that had problems with a particular Control Data BK7 series disc
drive. After experiencing lots of static related issues (status
errors), the customer installed a humidifier to increase the humidity
to an acceptable level.

In other climates, such as Singapore, the high humidity promotes mould
growth on magnetic media, although I doubt that mould would get a
foothold on disc platters rotating at 7200 RPM. :-)

I found this interesting Samsung patent whose inventors claim that
"flying height drops significantly in humid conditions" and that this
can be remedied "by increasing the temperature of the air flowing
between a slider's air bearing surface and the rotating disk surface
it accesses".
