I'm thinking of buying a 2 TB external hard disk, Seagate or WesternDigital, most probably Seagate. The price in the local shops is around Rs. 6000 - 6500, while online, it is around 5500, and at present, with the 10% discount when paying with card, the price comes to around 4500, which is 1500 to 2000 less than what the shops quote. There are a lot of negative reviews on the product pages of the hard disks, some saying that the hard disk stopped working after just a few days. So is it advisable to buy from Amazon or Flipkart as compared to the shop, and have members here who have bought online faced any problems? Another thing is, suppose the hard disk has a problem, and I claim warranty after say three months, and I get a new hard disk in return. If the warranty of the first hard disk was two years, will I get another two years warranty for the second hard disk from the date of delivery / invoice, or will it be from the date of delivery / invoice of the first hard disk, or will it be something else? And suppose the second hard disk also has problems, can it be given back in warranty, or is the warranty applicable only for the first purchase?
