I've been using my external hard drive for years and it has a lot of info on it. It has a USB 2.0 plug on it but my desktop has both 2.0 and 3.0. I plugged it in the 3.0 and one point and then also the 2.0 etc. Now when I plug it in to any USB port (2.0/3.0 and tries on windows 8 and 7) it says last time device was plugged it malfunctioned and can not be opened. I've tried uninstalling all the drivers in device manager and also tried updating. Nothing is working... Please help! I need the files off of there! Does it have anything to do with USB 2.0/3.0 anything?
