any suggestions?

[houbysoft.xf.cz]

What is your problem, exactly? And from the mkfs output, it looks that it worked fine, could you post the output of


sudo mkdir /mnt/mountpoint
sudo mount /dev/sdb1 /mnt/mountpoint

?

[homemadejam]

Have you tried formatting it using Gnome Partition Editor?

Jam

[kpkeerthi]

Just unmount it and plug it in again and run sudo fdisk -l

error : you must specify the filesystem type


Yes I have tried the partition editor, and it comes up with a few errors.

I can't unmount it because according to ubuntu... its not mounted.

In the computer folder, the usb drive logo comes up, and when I double click it, it says that its unable to mount the drive.

I prefer the Gparted Live-CD myself.
