NoTouch 500GB External Hard Drive USB2.0 with ContinuousData Protection Software - Retail (SATA)(http://www.ebuyer.com/product/147108)2. Western Digital Elements 500GB USB2.0 External Hard Drive- Retail(http://www.ebuyer.com/product/128465)They are both currently priced at the same price.I know that Western Digital HD is probably a better known brandbut I have read some reviews about their hard drives failing.I am planning on using the hard drive to back up some files & mp3s etc. from my computer.Any advice would be appreciated.
