I bought this hardisk from amazon 1 year back , it worked pretty good for first 6 moths but after that tranfer speed reduced too much. I had stored all my importand data , softwares , songs , movies and all in it but one day it showed my harddisk is empty , at first I thought it was some problem with my laptop and I checked it on my friends and it showed me same . Anyway I had a backup of my data with me , si it wasnt a big disaster. so I dont reccomend anyone to buy this hardisk unless they are willing to take risk
