This seems to be a reoccurring theme on that site. I suppose since I have never had to do it if someone invited me to verify the capacity on their machine I would be suspicious.
I verified its capacity at the shop itself on computer. later when i copied some files on pendrive. it start showing the files on the pendrive. However if I remove the pendrive and again connect it with computer, every thing simply disappears. The pendrive remains empty and showing full available capacity.
My guess is someone got a hold of some small capacity and/or defective chips for really cheap and tweaked the firmware to make them seem bigger.
