Hello, Recently I purchased one kingston pendrive of 80GB from unknown person. 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. I could not understand the reason. One of my friend told me that 80GB pen drive is fake. Any help would be appreciated.
