My Laptop Wont Recognise The Wd166e1ms And I Cant Find A Driver

I'm sorry to hear about the issues you're having with the external drive. In order to get the external recognized you can try the basic troubleshooting steps:

1. Try a different USB cable and plug the drive in a different USB port to see if it will be recognized.

2. In case it is still not, plug it in a different computer - that is the best way to see if the problem is with the drive, or with the motherboard of the computer.

Basically, this drive relies upon a driver that is build into your OS so it should be recognized once you connect and initialize it. However, since it is not recognized once you connect it to the computer you can check for the latest firmware and drivers for your external drive:

If after these steps it's still not recognized, and you have valuable data you want to extract from the device, then I would suggest to contact with a data recovery company and see if your information could be extract from there. Here's a link with WD data recovery partners:
