I've observed these noises and believe it has something to do with the
Predictive Failure Analysis that the drive does.  According to IBM's web
site at: http://www.storage.ibm.com/hdd/ipl/oem/tech/pfa.htm:

"A (sic) periodic intervals, PFA's Generalized Error Measurement (GEM)
automatically performs a suite of self-diagnostic tests which measure
changes in the disk drive's component characteristics."
