I have a very wierd problem, I am using a DYNEX 4 port USB hub at my home, and when i tried to plug in a portable hard drive that i generally just use in my work laptop into it, and now now the hard drive no longer works, so at work today i put a new hard drive in the portable case and it worked fine on my laptop, so i bring it home again thinking that the other hard drive has just bad, and now the same thing, so i even went to my car brought in my laptop and it no longer worked there either, so i fried two hard drive by plugging them into the hub, and i tried transferring some files to my jump drive plugged into the hub and now that is shot too, has anyone ever heard of a hub causing all of these problems, and that has to be what it is, I would really appreciate some feedback, thanks
