How do you tell if an external hard drive is dead?

My younger brother received a 200GB Maxtor external hard drive + enclosure from our parents about 6 to 18 months ago.

The drive worked fine up until Saturday.

On Saturday, I moved the drive from his room to my room to move some files to my computer from his.

I first turned off the drive, then I unplugged the USB and power connectors.

My computer was alraedy on.

I plugged in the USB and power connectors, then powered on the drive.

My computer made that noise it makes when a USB device connects. However, there was no drive on the My Computer list.

I checked Device Manager, and there was a new USB Hard Drive there.

I could not understand why this didn't work, so I simply tried turning things on in various orders (my computer and the hard drive). None of that worked either, although I did discover that my computer would not boot properly if the USB hard drive was turned on before my computer.

So I gave up, and moved the hard drive back to his room and plugged it all back into his computer (Everything was off).

On Monday, he tried to use the drive again (he plays games from the drive because he has very low internal disk space). The drive now does the same thing on his computer. It does not show up on the my computer list, but it shows in device manager. Sometimes in device manager it shows up with a little yellow exclamation point over the icon, and sometimes not.

This was the main problem with the drive. After testing it a few more times with these results, the drive showed another issue. Sometimes when the power rocker was flipped, it would not activate.

Sometimes when the power rocker was flipped, the drive would stay off (no light, no spinning sound), however the computer would make the "USB device has been connected" noise.

I am starting to believe the drive itself is dying or dead.

I would appreciate any advice on how to test or advice on the situation.

If you can remove it from the enclosure, put it into a known working enclosure or put it into a PC and run some diagnostics on it.
