Same experience here. If you can get the 9241 to recognize the ST1000, the receiver will eventually start freezing and then lock up completely. These are brand new Seagates that pass all Seatools tests. The 9241 simply does not like the ST1000.Well I replaced it and it works kinda. It keeps freezing up the whole system. I have to reboot it all the time. Could it be a bad Hard Drive right from the factory? Or what other choice to I have now for a 1TB Drive. Dont really want to try another ST1000VM002.
