Question External Drive Suddenly Not Showing Up

I rebooted my macbook pro (OS 10.7.5), and now my external drive that is plugged in is not showing. In Disk Utility and the Desktop, it does not show up, either. Before I take my computer in, I was wondering if there is some trouble shooting I can try?

I did run OnyX before rebooting, and went through several maintenance and cleaning operations.

thanks for any help.

It's not your system, it's the external.

First check the connections. Try a different USB cable or port. Try a different power adapter if possible.

as I mostly use linux when I have those sort of problems I get my friend to try the affected USB on his Windows 7 machine and most times Windows detects it so he safely removes it and its fine.
If he has that kind of problem I install it on one of my linux machines.
I do have a G3 Mac but we havent had to use it yet.

Is it a Western Digital?
