# 章 3. Formatting Disks with KFloppy

To use KFloppy you must have either a 5.25" or 3.5" disk drive connected to your system. Insert the disk you want to format. Do not mount it. Then, select the appropriate options as described below.

# 3.1. Floppy Drive

Select the drive that contains the disk you wish to format. For those of you not familiar with PC drive labelling conventions, letter `A:` corresponds to the `fd0` device and `B:` is the `fd1` device. Almost all new computers will only have one 3.5" floppy as their `A:` (`fd0`) drive.
