Problem sa particioniranjem: fdisk

Malo sam se igrao sa particioniranjem preko fdiska u terminalu prateći upute odavde: http://tldp.org/HOWTO/Partition/fdisk_partitioning.html.

Koristio sam usb stick od 4 GB i naišao na problem prilikom montiranja particije nakon particioniranja. Preko komande sudo fdisk -l saznao sam da je stick označen kao /dev/sdb.

Postupak:
Pokrenuo sam fdisk u terminalu komandom sudo fdisk /dev/sdb
Na sticku su već bile dvije particije - /dev/sdb1 označen kao Test i /dev/sdb2 označen kao Test1, koje sam obrisao pomoću komande d prateći upute na ekranu:

Napravio dvije nove particije, prvu od 2 GB a drugu od ostatka:

Kako su obje u linux datotečnom sistemu (pretpostavljam ext3 ili ext4), odlučio sam prvu pretvoriti u fat32 dok drugu ostavit kako je:

Pomoću komande w zapisana je particijska tabela i izašao sam iz programa:

Izvadio sam i ponovo ubacio stick i prva particija (ona sa FAT32 Fs-om) se automatski montira mada ali i dalje ima istu oznaku kao i prije nego što sam pokrenuo fdisk - Test, dok druga particija (ona sa ext3 fs-om) se ne očivata pod Nautilusom (slika) dok je vidljiva kad pokrenem sudo fdisk -l u terminalu:

Nisam siguran dali sam dobro odradio postupak, ili možda trebam dodatno formatirati particije sa mkfs alatom? Iako znam da sve ovo mogu na jednostavnij način napraviti sa recimo Gparted-om, želim naučiti što više raditi u terminalu.

Sorry na dugom postu 8-)
