Problem With External

i have a 320 gig external hard drive. i had it for a while now and recently its been giving me some problems.

when i plug in my external it loads fine, but when i go to look into it, it freezes everything on my comeputer, it shuts down windows explorer and everything. i dont know what i can be, i thought of the possibility of having a virus on there but i scanned it and nothing came up.

if any of you know what the problem might be, please provide some help.

 

I can not help you with that.
But here is a source I found.
