Hello,

Running Fedora 14 with bash shell.

I have a USB Drive connected that I need to format from the command line.

The drive is always located at /media/OCH

I want to format it to be ext4 format with the same name as before "OCH".

Can you please provide me with the bash command to do this from inside a shell script?

Thanks!
Jason

mkfs.ext4 /dev/sdx -L OCH


Where x is your USB drive. might be sda , sdb ,sdc.. or hda,hdb,hdc
if's it already mounted type mount to find out.

There are several mkfs commands. Depends on what filesystem you want the format.
First, umount the device.
umount /dev/sdX

Open in new window


For fat32:
mkfs.vfat /dev/sdX

Open in new window

For ext3:
mkfs.ext3 /dev/sdX

Open in new window

For cramfs:
mkfs.cramfs /dev/sdX

Open in new window


and etc...

Something's not working the way I was hoping...

If I run
sudo mkfs.ext4 /dev/sdb1 -L OCH

Open in new window

then I get error:
/dev/sdb1 is mounted; will not make filesystem here!

Open in new window

 (This occurs as root or as a privileged user.)

What am I missing?

You need to unmount it first.

Cannot format that is mounted.

"sudo umount /dev/sdb1"
