I’m also having the same problem. One slight difference is that when my problem began, occasionally when my drive was plugged in, it would recognize it and begin to search for drivers for a few seconds and then drop it before it could finish. But that seems to have stopped now. The power light flashes when it’s plugged in and I can’t remember if it did that before.
The Data Recovery Software idea doesn’t pan out, because if my computer doesn’t see the drive then the program doesn’t either. I hope somebody smarter than I am figures this problem out. I was so excited that my drive was under warranty and they would exchange it, until I realized they want to hold onto a stupid amount of money until they get my drive back.
