Less memory than specified a certain amount of memory is always taken up by the file allocation table.
This is normal for any memory storage device, when the device is formatted
first time; a file allocation table for a FAT is created. The FAT stores the

the drive by default .all USB flash memory devices use the FAT32 type of partition.

In addition ,are pre
installed with software that allows you to carry sensitive data in an encrypted
format and back up data .The preinstalled software on your drive is usually
installed in a separate partition .this causes the total available space on the
drive to reduce further but not much.
USB is designed such that
you can add up to 127 devices to one computer .This is accomplished through the
use of hubs .In a effect the hub expands the number of USB ports. The most
common hub is a 4-port unit which can be plugged into one of the USB
connections on your computer , giving additional 4 USB ports.
The specifications of a USB
states that the maximum length of the USB cable is 5 meters so you can not
extend it more that 5 meters without using a USB repeater cable .This cable
contains active electronics that boost the USB signal for maximum reliability
and performance over extended distances. Up to 4 of these USB active extension
cables can be linked to extend the distance between your computer and your USB
peripheral to up to 80 feet.
But the best solution is a
self powered hub with a fixed 10m cable that has a one port bus powered hub in
the middle.
