Hi, 

I hope someone can help me out. I've been trying to deal with this for days and I've HIT dead ends every time. 

(Some info about my hardware: My laptop is a Dell ultrabook  with windows 8.1, my two external hard drives are WD my passport ultra, 1 is 1TB and the other is 2TB.)

So, a couple of days ago I was messing around with some virtual drive and decided to unmount it. Unfortunately seems I might have unmounted my external hard drive instead. That was a WD my 1Tb passport but my 2Tb was still readable by my computer.

I tried the 1Tb on another computer and it was read fine and so I am SURE the hard drive itself is not corrupt.

My Laptop can't read my hard drive at all. I tried going to disk management (can't see it), tried device manager (Also can't see it). I've tried any and every suggestion I could find online.

I even decided that maybe if I formatted my 1Tb hdd, i would be able to open it again on my computer. So I went ahead and moved all my data (using a different computer) to my 2Tb hdd. I did a quick format bc I was short on time but my laptop was still not able to read it. But here's the kicker, After moving all the data to my 2TB, my laptop can't read that hdd anymore either. (It still works on other computers)...

Oh And the other computers I've tried the hard drives on, both have windows 7, so I'm also starting to wonder if its a windows 8.1 issue?


So does anyone have any other suggestions  . PLEASE... Anything.

Thank You
