USB 8Gb partition to use Linux and NTFS

[cientocien]

Hi, i have a 8Gb PenDrive USB, i have ubuntu 8.04 live installed on this, iused the tuturial from

 pendrivelinux 

and it´s ok, i have my Linux Live on my USB working, but now i have a problem, in the tutorial we make 2 partition:

1: 750Mb primari partition, fat16 file system (active partition)
2: Rest of capacity of my USB, Linux file system

So, when i connect my USB PenDrive on my laptop running Windows i only can see the 750M partition, i tried to chage the size of the partitions but i don´t know why this don´t work, i just change the +750M for +6500M and the file system fat16 for NTFS or fat32, when i use:

fdisk -l

I only can see the USB PenDrive total capacity - 8Gb:

/dev/sdb1 - 8Gb - fat16

But if i use:

fdisk /dev/sdb1

p

Now i can see the 2 partition with the correct size and file system, but now is:

/dev/sdb1p1 - 6.5Gb NTFS
/dev/sdb1p2 - 1.5Gb Linux

What´s happening?
What´s wrong?
Am i doing something badly?
What´s /dev/sdb1p1?

Ok, that´s all my question, i hope someone can helpme.

Thank´s
