It might bewindows putting the drive to sleep and then not being able to wake it up.
For Windows 7/Vista/XP:

I'm pretty sure all power management stuff is turned off on my computer. Checking the root hubs was one of the first things I did, followed by uninstalling the goflexes, restarting, and letting the drivers reinstall. Still the same behavior. And now, the drives are randomly starting to say they need to be formatted. This is making me regret purchasing two of these and I might go frigg'n caveman if I lose BOTH drives' data permanently at the same time.

BTW, both write caching and hot plugging are on, so unplugging and replugging the USB or turning them off and on on their separate power strip (with a 5-10 sec delay) should not be corrupting the drives.

Actually, the USB 3 ports don't give me the power option at all. But the computer is set for performance and the USB 2 ports are not allowing power down. Is there some way the USB 3 ports might have their own hidden settings or always allows power down?

Discovered the power settings inside Dashboard. Made no difference. And still no power tab in Device Manager. Also tried turning on ErP in bios... no effect.

The seagate cables are garbage.
After hours of messing with what I thought was a bad motherboard -- TWICE, bad front panel ports and every other cable, I found the issue was the Seagate Goflex cable.
Harddrive Worked fine on USB 2.0 and some USB 3.0 ports, but it would lockup the computer or fail to be recognized on certain USB 3.0 ports.
Replaced the goflex cable and now the drive works reliably on all ports.
The cable I used -- Cavalry CBUSB20002 20" USB 3.0 Y-Cable - Standard-A to Micro-B Connector M-M (got from Newegg). I thought it was a power issue, so I got the cavalry cable with the extra USB power cable at the end... didn't need it. It was just a bad usb 3.0 cable.
Do yourself a favor... replace the cable with a good one.

I have a Gigabyte GA-Z77X-U5DH motherboard with an i7 3770k CPU board and am having the same issues.
If I do a warm reboot, my 1.5TB USB 3.0 GoFlex Desk goes MIA, requiring me to unplug and replug the drive in. The drive works fine from a cold boot. Can anyone offer some insight into this frustrating issue.
