WD hard-drive suddenly not recognizing! Help!
I have a 2TB WD hard-drive formatted to FAT32. All of a sudden, it has stop recognizing on my Mac OS X (10.5.8). The drive is plugged in and the power turned on. The light doesn't flash like it use to, but stays solid. When I plug the drive in the light stays solid, and is not recognized on the desktop. The drive is not recognized in Disk Utility either. I have unplugged all of the chords, USB plugs, power supplies, restarting the computer and nothing seems to be working. The drive works on my normal PC computer without problems. I have tried plugging in my other WD drive on the same Mac but neither of them work!
Please help!
Thanks in advance!

I'm assuming the external hard drive is STILL being recognized fine by other computers.

The USB port you plug the external drive into MUST be able to actually supply 500 ma of current.

The external hard drive may NOT be recognized when it's plugged into a USB port in an external USB hub. or a port on the front of a desktop case.

Troubleshooting USB device problems including for flash drives, external drives, external memory card readers.

In addtion to the info at that link....

For some desktop mboards you can have problems when an external hard drive is plugged into one of a pair of USB ports on the back of the case that are connected to the same USB controller, if there is another device plugged into the other USB port for the pair, because the pair can't actually supply 500 ma per port - they can only supply 500 ma in total. Usually those pairs of ports are one above the other, not beside each other. If you have two devices plugged into such a pair of ports, try plugging one of them in elsewhere on the back of the computer.

For MANY laptop and netbook mboards similar applies. The built in USB ports often cannot actually supply 500 ma per port - they supply 500 ma in total for two ports that are close to each other. In that case, the external drive should work fine if it's the ony thing plugged into the USB ports built into the laptop or netbook, or if you have more than two ports, the only thing plugged into two ports close to each other.
