A 36LZX or 73LZX? If so they do make an awful screeching noise. When I got mine (off eBay) I thought the bearings were on their way out, but searching Hitachi's website (Hitachi now own IBM's HD division) threw up this http://www.hitachigst.com/hdd/support/qcheck.htm#a4 Mine makes this noise a lot more frequently than once per minute that they state and it's extremely annoying. My Seagate OTOH is almost silent except when it's doing some serious thrashing. HTH Mark
