Hard Drive breaking chassis!?

So, I had a hard drive chassis burn out on my the other day. I was told it might be an issue with the wrong power supply. So I looked inside and I saw the burn point, looked like the hard drive might be alright. It was suggested to me to take that hard drive and put it in another chassis to see if that would work. Unfortunately, that chassis immediately burnt out to and the smell was almost immediately noticeable.

My question is, what is going on? I used the exact same chassis it should be in, double check the power supply, how is the hard drive causing the chassis to burn out?

how does a chassis burn out?

Are we talking about an external hd enclousure?

yea, there is probably a short of some kind on the board on the hard drive. Its happened before. Don't put that drive in anything else, and junk it. If you need the data off of it, you could try swapping the board on the drive with another one from a Drive that is exactly the same (firmware and all) if you have the resources.
