I recently bought a sony flash drive of 32 gb by a recommendation of my friend. But on recieving I was surprised by the fact that its not installing. After telling the problem to salesman he replaced the piece and gave again the same kind of it. This one worked but its speed was too slow while copying. I tried to move around 3gb of stuff from my pc to it for which it took almost 30 mins. And when I tried to insert it in another pc. It said the drive needs to be repaired. And I was not able to move those files. Instead of sony. I bought hp flash drive which worked quite well. But now onwards I dont trust sony. Coz they are cheaters. They sell things at quite high price. I bought it for 999rs. And usually their things are of no use. So for me. Its a big NO! To Sony.
