Hi,i m a system builder & deal in selling machines for video editing…Recently i bought 10 WD10EARS Hard drives as i m a system builder…at the time of installation i found it to be doing at snails pace…it took 40 minutes for an install of windows xp sp2 on following configuration…Gigabyte GA-G41MT-ES2L motherboard,intel core 2 duo 2.66-3mb cache,Kingston 1333 DDR3 Ram,Liteon DVD-RW,Cooler master 400w SMPS…al brand new…it was frustrating & irritating & i guessed something was wrong…so keeping everything else same i changed hard drive & used an old WD 1tb with 16mb cache which i have been using,which is supposedly slower than this one…but hurrah installation was completed in flat 20 minutes…i thought there must be something wrong with this new one so opened another new one & installed windows on it,but it was same story…40 minutes…opened another new one,but same time again…40 minutes…well,then i created partitions & copied a 40 gb folder from old HDD on one partition of new HDD…copying took 11 minute,then i copied same 40 gb folder from one partition on new HDD toanother partition on same HDD…it took 25 minutes…This all was tried on 3 brand new HHD’s with same result…so what is wrong with much aclaimed 64 mb ecofriendly etc etc…even customer care at WD couldn’t give satisfactory solution,one of them told me to put jumper at no. 5 & 6…but no improvement…i was feeling like i m using an old P4 with 1.6 ghz cpu machine…can WD solve this problem.
