the very first lacie i bought did not work out of the box. they replaced it and now i have one on my win 7 machine (running for over 2 years, was on my dead win xp prior to my win 7) and i have one backing up my imac for over a year. no problems with either. i think hard drives can be a crap shoot. people report problems with all brands. go check out the review on tom's hardware. there was a review from a company, russian i think, that retrieves lost data and they broke down which drives failed on a percentage basis. seagate did not come out looking in that review.
