In any USB device there is a memory space called device descriptor. This space has information about the USB device itself. In a USB mass storage device, the memory size of the pen drive is one of the info. This can be modified to any number irrespective of the actual physical memory available. This is exactly what had happened to you. There is no physical memory. The file system reads this info initially. But when you try to transfer the data, the FS will not be able to find space on the device.
