Create an EXT2 formatted drive in Linux
These can be copied and pasted into a terminal
*** the /dev position of the drive (USB / Firewire / CRU) must be verified beforehand, and these commands might need to be modified to fit ***
Below example shows /dev/sdb is the target drive to format, your's will likely be different.
parted /dev/sdb mktable msdos
parted --align optimal /dev/sdb mkpart primary ext2 1 100%
mkfs -m 0 -b 4096 -N 2000 -I 128 -t ext2 /dev/sdb1
