I have a Seagate St225 20MB drive which sounds the same way.  I've often
worried about it, but it doesn't seem to get worse with time so I've quit
worrying about it.  It seems to me that this may be normal (produced by the
cooling fins or some such).  In any case, I find it re-assuring that others 
find the same situation with their own St225's.

P.S. If anyone else has one, and has found it isn't supposed to do that,
I'd like to know so I don't blow my disk...
