HDD warning.

I bought one of these a few months ago for data backup. I usually use 500GB drives which I have a few of. But I thought, lets go for something bigger. Bad Move!!!
It went pop the other day with a shed load of data from this year. I couldn't even recover it because the drive wasn't even spinning up! so that was a lesson learned. don't put all yours eggs... blah blah.
I'll be steering clear of these in the future.
