Any advice for USB HDDs? I own a WD3200BEVT-60ZCT0 that is on Nicedude's list at http://ubuntuforums.org/showthread.php?t=795327

hdparm doesn't work with USB drives, is there another way to disable apm or do I have to buy a new hard drive?

(if only the link above had been made a sticky topic I would have never bought a Western Digital drive!)
