in my experience, i have seen (by far) more maxtor drives die than other brands. just as a reference for the future, stay away from them.
on a brighter note, if the drive isnt spinning up, i would try and remove the drive from its usb enclosure, and connect it directly to a sata port. when the drive attempts to spin up, give a gentle shake, and it might wake up. if that doesnt work, try lightly tapping the side of the drive with a rubber mallet. best of luck.
