When possible, for Microsoft Windows users, we try to have drivers available for download through Windows Update for many of our products.
For those products, simply plugging in your device should cause your PC to download and install drivers automatically if your PC has Internet access.
See Technical Application Note 10359 for recommended USB 3.0 system components.
Users who continue to encounter errors should contact support.
This means that while that brand new USB 3.0 external hard drive you just bought will work just fine with your PC, it will only work at the much slower USB 2.0 speed. Depending on your computer, the chances are excellent that you can add two or more USB ports at a very reasonable cost (approximately $20 and up).
