WTF happend to my HD?

[Surgeon General]

Hello Guys,
O.K. Here is my problem. I recently lost al the data on my secondary hd. The format, fat32 is still present, and the folder labled "recycled" but nothing else, it looks just like it did when I first formated it.
Now my question is, how did I mess it up? I mean this is the first hd to ever fail on me and I don't know what it's suppose to look like. Is this a data loss as a result of some magnetic problem? or would that wipe the fat32 away as well?
I did move it form 1 bay 2 another, then next time I went to use it it was erased.
Did I bump it in movement? would that cause this problem?
I don't know what would cause all the data to just vanish. i need to run a read write test on it.
just woundering if anyone knew what would cause this.

I'm just wondering,are you hooked to cable modem,a buddy of mine near where I live when he first got cable had his HD hacked into and they stole all his games,just the games mind you,they did leave all his other stuff,but all folders to games were gone,this may not have anything to do with the problem that you have,but this is what poped into my head when I read your post

Hey pistol, Yeah I do have a cable modem, had the service for about 3 years now. I am running zone alarm as a firewall but who know? Well the hd that I lost was a secondary, just storage for apps, proggies, mp3's and a jpeg or 2 :D
