Mmm.. the infamous bug-of-death Seagate 1TB drives.
I wouldn't touch those with a ten foot pole, really.

WD seems to be the only safe brand for large capacity at the moment.

Perhaps in a year or so, all of the b0rked Seagates might be gone from retail channels, but until then it's a total 1/256 crapshoot at every reboot.
