Hi all,
I tried to use my mp4 as a boot disk for install Ubuntu on my new netbook, however, I followed a method on a webside use fdisk or some other commands to format my mp4.

The original size of my mp4 is 16G, however, when I plug it to a computer now, it only shows 10M!!! That is so frustrating~

I think there must be something wrong with the mp4.

I am really new for Ubuntu, so I tried some commands followed by some websites, and the results are as follows:

sudo fdisk /dev/sdb

Command (m for help): p

Disk /dev/sdb: 10 MB, 10469376 bytes
1 heads, 20 sectors/track, 1022 cylinders
Units = cylinders of 20 * 512 = 10240 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

Device Boot Start End Blocks Id System

----------------------------------------------------------------------------
Command (m for help): v
Remaining 20447 unallocated 512-byte sectors
----------------------------------------------------------------------------

I wish someone can help me.

Thanks in advance!

May all a happy new year!
