I have endured enough pain and suffering with my current Seagate GoFlex 2TB USB 3.0 drive being used for Time Machine on my mid-2011 27" iMac running OS X 10.8.2. It keeps turning off and disconnecting and its driving me mad. I have been on the phone multiple times with Apple Support and they feel the drive is the issue after all we've tried. I have scoured the Web and discovered many unhappy Seagate customers with Macs who made the mistake of buying this model of USB drive for backups. So, I am hoping not to make another mistake this time. Thus the request for recommendations of a decent USB Backup drive for use with Time Machine. If it happens to be available on Amazon.com that would be a bonus. Sometimes I wonder if I should have just bought a Time Capsule instead of a Airport Extreme but too late now. My hard drive is 1TB and I am wondering if 2TB for the backup was overkill, particularly where 250 gigs is given to a Windows 7 bootcamp partition that is not backed up. It's just for games. I do not create a lot of new data usually so one terabyte would probably be fine. It also does not need to be USB 3.0 since my iMac only supports 2.0. Anyway, I would be grateful for some tried and true advice here on a current model USB drive that is reliable and just works. That would be wonderful. Thanks.
