I was too an sad user of this drive until a month ago
The drive really dosent work well.
It gives a lot of probs (I got 1 replacements in last 6 mnts)
At last I stopped using it.And gifted to my friend

Now he is running for warrenty second time
If U still have any chance by convincing your hardware vendor to give some another flash drive of some other BRAND like trancend OR kingston then go for IT.
But if U cant,.... give it for warrenty
