Maverick, I have this same drive, and as yet not had any problems. I have had this happen before with another drive. I suggest the following:
First, uninstall in device manager.
Second, turn off the computer and unplug the drive.
Third, reboot without the drive so that it is not found.
Fourth, be sure to make sure device manager did not find it.
Fifth, turn the computer off, plug the drive back in, reboot, and
with any luck--it will work again.
Sounds like drive conflict, somewhere.
