I've been having the most trouble with this drive. I unplugged it from my laptop and it hasn't been detected since. This has happened to me before and all I had to do was plug it into another pc and back on the laptop and it worked fine. So I tried this and it didnt detect on the desktop computer, so I tried it with another desktop and it didnt work either on that.
So far I have tried:
1) connecting it to two desktops
2) checking the wire (the wire works)
3) reinstalled drivers and retrospect software
4) looking in disk managment and device manager (not listed in either)
I would also like to avoid opening the drive up.
