Do not install Windows 7 via USB 3
Recently, I was trying to install an Intel 320 SSD into my Lenovo X220 laptop. Since the X220 uses the a 7mm tall 2.5″ HD bay, this is annoying. Once I got the SSD drive trimmed down a few millimeters and installed, I had to re-install Windows 7 and this is where things went screwy.
