So you don't see a long black bar labelled "Unallocated" like
this?
Hmm...try the suggestion below:
"I recently installed an external hard drive and some similiar
problems. Turn your computer off, then unplug the USB cable and
then the power to the drive. Restart you computer, plug the power
into the hard drive, wait 10 seconds and then plug the USB into the
computer. This clears the hard drive buffer. See if the drive shows
up in disk management. Before formating, turn off your antivirus. I
had no problems once I did that."

Didnt really get this method. Isnt the USB cable connected to
the external disk and the computer at the same time, so when the
cable is pulled out, the power to the drive will "disconnected"
already. How to unplug usb cable, then unplug the power to the
driveTried this method, didnt work. Now under the safely remove
hardware, it shows up as "Generic USB Disk USB device" :S
