Recently my friend’s room mate got hold of a “Transcend 80GB USB Drive” .He instantly knew it was fake because nobody manufactures 80GB USB Drives.The capacity of any USB Drive is only in powers of two.This fake USB Drive looks exactly like a Transcend USB Drive except for the 80GB Capacity.If the manufacturer of this pendrive had some brains,he would have sold this fake USB Drive as a 8 or 16GB USB Drive instead of 80GB.

A Sony 64GB USB Drive turned out to be a fake USB Drive having only 249 MB of usable space.
