1. Why my 16GB pen drive show 14.4G only? is it not full capacity?
For hard disk manufacturer, one KB is 1000 bytes, one MB is 1000 KB,
and one GB is 1000 MB. If a hard disk is advertised as 500GB,
it contains 500 * 1000 * 1000 * 1000 = 500,000,000,000 bytes of space.
However, manufacturers of RAM don\'t sell it in even groups of 1000 - they use
groups of 1024. When you\'re buying memory card or USB, a KB is 1024 bytes,
a MB is 1024 KB, and a GB is 1024 MB. To work back from the 500,000,000,000 bytes above:
500,000,000,000 / (1024*1024*1024) = 465.66 GB
According to above calculation way, 4G is about 3.6G, 8G is about 7.2G,
16G is about is about 14.4G, 32G will show 28.8G.
