First of all I was impressed by the hard drive. She feels wertig and you get the feeling they really times holds a kick out of. So I fed them with your Data I wanted to back up but after a short time I was made into a paste that the disk has an error and needs to be repaired. Opt there the short variant appears to me that the bugs have been fixed. But the next time you restart the same again. The long repair variant I've tried but it did took more than 30 hours and an improvement was then also not occurred. I would not buy again, so it is useless to me
