Ubuntu Linux format USB pen drive

Posted by Vivek Gite [Last updated: June 20, 2008]

Q. How do I format a USB pen drive under Ubuntu Linux for ext3 file system?
A. You can format USB pen drive with the help of following commands:

[a] fdisk : Partition table manipulator for Linux

[b] mkfs.ext3 : Create an ext2/ext3 filesystem by formatting given partition name (/dev/partition)

[c] e2label : Change the label on an ext2/ext3 filesystem

First make sure USB pen is not mounted. Click on Places > Computer > Select USB pen > Right click > Select Unmount Volume.

Let us assume that /dev/sda1 is your partition name for USB pen. To format type the following command (Open X terminal and type the command)
$ sudo mkfs.ext3 /dev/sda1
Caution: Careful while entering device/partition name; wrong name can wipe out entire hard disk!!!
Now use e2label command to change the filesystem label on the ext3 filesystem located on device /dev/sda1:
$ sudo e2label /dev/sda1 usb-pen
You can also create an MS-DOS/Windows XP file system under Linux, enter:
$ sudo mkfs.vfat /dev/sda1

Now you are ready to use USB pen.

    This guide was simple and effective. I have a Kingston 2 Gb pen drive. When I transferred some files into it from Ubuntu, the pen drive stopped working normally in Windows. When I right clicked it’s icon in windows, instead of ‘Open’ in the context menu, it showed some garbled characters. I could not format it in windows. Following the instructions given above I was able to format it to FAT32 and use it again normally.

    Dear Mr. Gain,

    With regard to your posting, I wish to bring to you notice that nobody the phaque cares what you do with your pen drive. The problems you have stated are bound to happen since the hardware/software that you are using are totally jali as you yourself. If in future, if such a problem arises, I would give you a plain and simple solution and that is, you can take your pen drive and shove it up…you know know where…sideways.

    With regards,
    Axl

    The problem you demonstrate is called narcissism. I have known at least two persons with your symptoms. Unfortunately, psychiatric help for this condition is very rare.

    Sorry,

    Hey, come on, be nice folks. Mr. Gain brought up a valid point. I do use VFAT on USB sticks for the exact purpose of going back and forth between my GNU/Linux box and MS Windows. What Mr. Gain shared above is actually yet more evidence that our favorite platform (GNU/Linux) is superior to the offerings from Microsoft. GNU/Linux made that USB stick of his *truly* interoperable, not the farce that Microsoft pretends to promise.

    I have a solution more easy:
    Just install gparted from synaptic.

    Is easy, simple and you can format and partition in all formats.
    You can format pendrive, zip, diskette, disk, etc.
