Depends where the noise is coming from. A hum or buzz is probably
coming from an old power supply. Hard drives themselves usually make
more of a clicking or grinding sound when they're dying. Usually due to
stiction or something. The fan could also be the culprit, but my money
is on the power supply.
Isolate the source of the noise. If it's the fan, it won't mean much
for the integrity of your drive or the data on it. You should replace
the fan, however, to ensure your external drive receives adequate cooling.
If it's the power supply, you should be fine until the supply dies.
You may want to check that the supply voltages are within acceptable
range however. A hard drive that is not getting the required power can
have read/write problems. This will usually manifest itself in read
errors. However, you'll probably want to do something about replacing
the supply/enclosure before you start running into write errors.
If it happens to be the drive that is causing the noise, definitely err
on the safe side and backup your data to another drive. You may wish
to continue using the drive for files that you don't really care about.
But definitely stop storing important stuff on there.
