External HD issue?

I upgraded my internal HD and was going to use my old HD for a external HD backup. I have it in a enclosure hooked up with a USB cable. I can not get the external HD to show up in disk utility to re-format it. I've tried restarting the computer and left it plugged in over night. Any suggestions would be great. Not sure what it means, but when I plug in the HD it beeps a couple of times.

I suspect the external carrier you're using is either defective or of the incorrect type. Also check the drive mounting to the connector within the carrier. You need an external carrier that is capable of converting a SATA HDD to USB in order to use it.

I know for a fact that you can do this so don't lose all hope. It may be something as simple as a loose connection either between the cable and the enclosure and/or between the HD and the connection inside the enclosure.

I have used this enclosure before without problems. So that's what's got me confused. Any chance this could be because the HD was in the laptop as a startup HD?

Ok thanks

I've been working on the HD and I still cant get it to mount. Any more suggestions?

Pop it back in whatever machine it came from and see if it works okay. Perhaps the drive has died.
