Dear friend,
Whatever be it please dont go for a WD drives, Basically I am from mumbai, I have had many failed seagate hdd's but the same got replaced within a week or at the most 2 weeks. While in the case of WD their replacement litrally sucks, It is better to opt for a second hdd rather than wait for a replacement of a WD drive.
In my case I sent 4 WD hdd's in last january (2010) for replacement, first of all I called them almost for a month's time, the courier person came for a pickup after almost 40 days, then again i had to call them daily i received the replaced hdd's after a month. but to my dismay out of the 4 hdd's 2 were working and 2 were not.
So again i had to go thru the same rma procedure and again out of 2 one hdd received was faulty, now it is over a year that I am waiting to receive the drive.
and calling them is a big head-ache. also their email reqplies are all use-less and more i guess they just copy paste the replies.
