How to format/partition SD card?

I would recommend installing gnome-disk-utility , which allows you to add / remove partitions, format the partitions with a given filesystem, and change the volume label. Of course, for an SD card, you'll probably just want to format it (using FAT if you need Windows compatibility or Ext2 otherwise).

I don't think this application ships with Kubuntu by default, but it should be available in the repos. Install it with:

sudo apt-get update
sudo apt-get install gnome-disk-utility

I would recommend installing gparted. It will let you manage partitions, as well as formatting and labelling the partitions using the file format of your choice. You can install it by entering:

sudo apt-get update
sudo apt-get install gparted

Once installed, it will be made available under System -> Administration.

** Be careful about where you use GParted. It can be dangerous. **

Description:

A partition management utility Partition Manager is a utility program to help you manage the disk devices, partitions and file systems on your computer. It allows you to easily create, copy, move, delete, resize without losing data, backup and restore partitions. .

Partition Manager supports a large number of file systems, including ext2/3/4, reiserfs, NTFS, FAT16/32, jfs, xfs and more. Note that to gain support for a specific file system other than ext2/3/4, you should install the corresponding suggested package. .

Partition Manager is based on libparted (like gparted) and makes use of the KDE libraries for its user interface.
