From the HDA desktop (or using VNC), [[Open Terminal as root]] and type '''gparted''' to launch the GParted application.
To know what device (/dev/sd<x> sdX) you need to select in GParted, use the following command, in a Terminal:
<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px;">
</div>
Find the row corresponding to your hard drive, and look at the end of the line to identify the correct /dev/sd<x> device to select in GParted.
Example:
lrwxrwxrwx 1 root root 9 2010-02-18 03:24 ata-Hitachi_HDS722020ALA330_JK1131YAGDU37V -> ../../sda<br/>
lrwxrwxrwx 1 root root 10 2010-02-18 03:24 ata-Hitachi_HDS722020ALA330_JK1131YAGDU37V-part1 -> ../../sda1<br/>
lrwxrwxrwx 1 root root 9 2010-02-18 03:24 ata-ST31000528AS_6VP08W65 -> ../../<strong>sdb</strong>
</div>
In the above example, /dev/sdb would be what I would select in GParted. sda in my primary hard drive, and sdb my second hard drive.
You 'll probably want to create a single partition, and format it as ''ext3''.<br/>Note that Windows can't read ext3 partitions, so if you want to read your disk on Windows, you should format as NTFS instead. And instea, and you should do that on Windows before you connect the drive in your HDA.<br/>
Remember that using NTFS partitions on Linux will be slower that using ext3 partitions, so you should only use NTFS if you really need it.
