I have two external USB 3.0 Seagate expansion drives connected to my Windows 8.1 box (directly, no hubs). I've got them both in a Storage Space (thank gosh), and they keep powering themselves off. This leads to quite a few errors in the System log where NTFS complains it can't finish what it's doing to the drive. I also see disk events about "surprise removal".
Even worse now, one drive powered itself off and wouldn't turn back on, leading Windows to see an unrecognized USB device. This upset the Storage Space, which complained of reduced integrity. Rebooting did not help. I had to unplug the power to the drive and plug it back in. The Storage Space then repaired itself and all has been well, except for the original issue of the drives powering themselves off randomly.
I've tried Segate's tool (which doesn't work on Windows 8 btw) and setting the drives to never power themselves off doesn't help.
Additionally, I've tried turning off power management on all USB root hubs and tried connecting the drives to USB 2.0 ports to no avail.
Any suggestions on how to fix this?

Same exact expansion drive (2TB) issue and configuration here. Win 8.1. "Surprise removal." It crashes Plex Media Server frequently. I'm nervous this is a hardware issue and should return or exchange it (I've only had it two weeks).
Does anyone at Seagate have any suggestions?

Also - this occurs about once an hour (or more) if I'm streaming any media off the drive (low I/O - a couple % according to Windows task manager).
Recovery is fast, within a few seconds, but it still has me concerned.

Please let me know if either of you have tried updating your systems' USB drivers:
Does the same issue occur when you switch ports or computers?

I have the latest USB drivers for Windows 8.1.
I've tried various USB ports, I have 3 clusters of USB ports, two on the motherboard, 1 of which is USB3, the other USB2. The 3rd USB group is USB3 and a front panel group.
Same behavior on all three (not that I'd use anything but the 3.0 ports anyway).
This sems to be a power issue - but I've disabled HD sleep, and various USB sleep settings.
I tried to use the Seagate manager utility, but it doesn't seem to work in Win 8.1, as my drive doesn't appear in the list. The download here does not list Win 8.1 as a compatible OS, just Vista and Win 7.
