|You don't need a specific driver, as already stated. |
It's the external enclosure's circuits Windows detects - when they're detected correctly, the hard drive inside the external enclosure is detected correctly - neither needs specific drivers.
The external hard drive MUST be plugged into a USB port that can actually supply 500 ma of current. Even then, it may not be detected correctly when it's plugged into certain USB ports.

In addition to the info there...
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.
In other words, the external drive should be detected correctly when it's plugged into at least some USB ports, in at least some circumstances.
If it isn't detected properly, the only things left that could be wrong, assuming the USB cable came with the drive (if it didn't it may NOT be adequate) , are
- the circuits in the external enclosure are damaged,
- or - there's something wrong with the cable between the external drive and the USB port - try a different USB cable,
- or - there's something wrong with the USB port connection on the external drive.
The most frequent reason for the
- first and third of those is someone dropped the external enclosure.
- second of those is the cable was unplugged too often by pulling on the cord instead of the connector on the end of the cord, or the cable was yanked on.
If it isn't detected correctly because of any of those reasons, it won't be detected correctly by ANY computer.
New external hard drive enclosures are relatively cheap to buy.
The hard drive inside the external enclosure can be removed and connected to a computer one way or another such that you're not booting the other computer from the drive to check out whether it's still okay.
2.5 " hard drives are much more fragile than 3.5" hard drives and more likely to have been damaged if the external enclosure was dropped.
