I just bought a new 300GB Seagate drive. I take it home, pull the smaller drive out of my external enclosure and pop this one in. When I turn it on however, I am greeted by the wonderful sound of the drive repeatedly trying to start spinning and failing. To make sure it isnt a bad drive, I stick it into two different computers--both work just fine, and I even formatted and copied a bunch of data over for more than three hours. When I put the drive in the external enclosure though, it does the same thing, despite the enclosure working fine with its old drive (its a third party enclosure meant to do just what Im doing with it). A few more points, to cover as much info as possible:

--the new drive is ATA100, the old is 133, so I dont think its a compatibility issue
--the new drive draws significantly less power than the old, so I dont think its a powering issue, despite what it sounds like
--it isnt a jumper issue, I made sure the jumpers were set the same on both drives and even tried other jumper settings just to make sure
--it isnt a formatting issue; the enclosure would work fine regardless of what it is formatted as, and anyways, it still does it after formatting

Im really stumped on this one. I would very much like to be able to use this drive externally without having to buy a new enclosure. Any ideas on what the hell is going on here?
