Unreliable

Have had two fail within a couple of weeks of being installed in a new computer. It's exactly the same failure: one of the hard drive ports becomes intermittent and in doing so has damaged a couple of drives in the process.
My biggest beef is that ASUS will not do refunds, only exchanges, and will not release any information on what they find wrong, so there's no way to try and figure out whether it might be something in the installation.
I recommend doing business with someone more helpful!
