Bad hard drive--bad external enclosure?

I recently bought a Seagate 500 GB hard drive on sale from Best Buy and a Vantec Nexstar 3 external enclosure. Installed the drive in the enclosure, attached it to my MacBook Pro, reformatted the drive, all fine. Then, as I prepared to begin copying files...knock...knock...knock. The drive wouldn't dismount, the system wouldn't shut down, what a mess.

I returned the drive to Best Buy and exchanged it with no problems. The question now is, is there something wrong with the enclosure? The knocking sound clearly involved a movable part, so it had to be coming from the drive itself--but could there have been something wrong with the enclosure that would have prompted the drive to start behaving this way? I don't want to put the new drive at risk unnecessarily.

It's unlikely that it's the enclosure. Better safe than sorry though - go buy one from a big-box place where you can return it and test it!

An enclosure is really just an interface between IDE/SATA and USB/Firewire. All it does is translates commands from one protocol to another. I would say it's the drive. :-P

I would say that it's the enclosure, if repeated drives also 'fail' inside it.

If.

I agree with you, but so far the story only encompasses one drive.

I'm curious. Which chipset does the enclosure use?

Not sure what the chipset is--Google turned up the chipset for the USB-SATA version, but I have the USB-PATA version.

User reviews on newegg show a number of Mac users using this enclosure with no problems, and one user who couldn't get a Seagate drive to mount (but had no trouble with a Hitachi drive). That's a different issue from what I had--the drive mounted just fine, at least until it started knocking.
