I recently purchased a Seagate Backup Plus w/ USB 3.0 Desktop Adapter for my new 2012 11" MBA. But I am having issues detecting this drive with my MBA. The drive spins but neither Finder nor Disk Utilities can see it. If I plug the drive into a Windows PC it can detect it. So the Tech Support at Seagate said that it should be operational as evidenced by Windows being able to detect the drive. I decided to try plugging this in a few more times and finally my Mac recognized the drive. I formatted it and backed up my system via Time Machine. The next time I booted up the drive was once again missing. I unplugged the USB 3.0 cable from the drive several times and reattached it and it eventually detected the drive. Has anyone found a solution to this, because playing around w/ the cable and hoping for the best does not seem like a sound solution. I have read on the Seagate forums that the issue exists, but there is little support and no solution. As far as why I chose this device, I was hoping to upgrade to thunderbolt sometime in the future, and I had read reviews that WD My Books had poor build quality. However, my My Passport is amazing and it is making me reconsider. Thanks in advance!
