I have a "My Passport" I've been using for quite long time and was so satisfied with everything including the speed of USB 2.0 (As non of my laptop/computers had USB 3.0).
Finally, about a month ago, I decided to order an PCI Express x1 USB 3.0 board. It got here about a week ago and so I installed it the very same day (and also the drivers that came with it).
I plugged the HDD in and tested the speed using some programs and got to 74MB per second read and write and got more satisfied with both my card, and the HDD. Now, a new problem has showed u; the HDD doesn't work on USB 2.0 anymore and I get a not recognized USB device ballon in Windows, and nothing happens in my mac. (it doesn't even show up in Disk Utility of mac and the partition management of Windows). I bought an 8GB USB 3.0 drive to test and see if that's the PCI that killed a component on the hdd but the usb worked on 3.0 and did so on 2.0 as well. I tried another computer from a friend and same problem with hdd (not working on USB 2.0 and did on onboard 3.0)
