I have a Western Digital Elements harddisk, and a couple of weeks ago I plugged it into my desktop computer. It worked perfectly, then a couple of hours later I was going to plug it into my laptop, it worked perfectly fine.
But here's the problem, when I once again plugged it into my desktop computer, the computer didn't find it. I can't find it in "My Computer".
What should I do? I don't want to lose files on that disk.
