How do I create this pen USB and use it like a pc with 64Gb of hdd space.
Just connect your USB drive, partition it and format with any file system you want (you may want ext2) and install any distro you want like on a HDD.
You have to pay attention to GRUB installation, to put it on USB, not on your internal HDD.
I have got a 16GB USB stick with 5GB system partition ("/") and 11GB /home partition. When I'm on my computer, I just boot the system from HDD and mount my /home from USB, when I'am at another computer, I can boot the machine from USB. Do not put swap on USB stick.
I have two warnings for you:
1. Flash memory has large, but limited number of write/erase cycles possible. USB sticks do not have advanced techniques used in SSD drives to make their life longer.
2. The performance of flash disk formatted with ext3 is much worse than formatted with FAT32.
