I don't buy Seagate drives anymore, too many of them have failed on me in less than 12 months (less than 6 months in some cases), although I should add they were all external models, even so it's put me off the brand.
By comparison, all my WD and Hitachi drives have given me no cause for disappointment after 18 months and still going strong.
for me all WD drives failed...i never had a Seagate
now i got a 500 GB SAMSUNG F3 which is PERFECT
(a shame that Samsung doesn`t make them anymore)
