I'm only having problems with a 120g external hard drive I received yesterday. I keep getting disk errors, fix them and then get the same error again. If I barely touch the hard drive or computer, or if the table moves, the hard drive spins down. I tried it on 5 different USB ports on 2 different computers, both are almost new. I have emailed the seller and will update their response.
