i have a new system(see info below) 1.5 months old

my wd 500 gig sata 11 is failing

i have been running into problems installing sp1

d/l several times

i bought sp1 from ms

i have run tests with one care it stated no problem

i ran sfc it stated some errors that could not be fixed

i ran other test on line also stated no problem

i d/l wd diag tools it stated a problem

i called wd support they confirmed the hd is failing

my question is could i have known about this hd failure from the
beginning or

the way things happened was the only way

and could the hd being defective be my problem for not being able to
install sp1

i would like to help myself as well as others not knowing that there
maybe a problem
