View Full Version : [ubuntu] cannot format usb drive

Suddenly my 4GB usb thumb drive cannot be formatted by Ubuntu or Windows.
My usb drive does not have any switch on it to make it readonly.

$ sudo mkfs.ext3 -F /dev/sdg1
mke2fs 1.40.8 (13-Mar-2008)
/dev/sdg1: Read-only file system while setting up superblock

Have you tried gparted in Ubuntu in system-admin-gparted.

Or right clicking on the icon of the thumb and then format.
