Add PartitionOnce the virtual disk is added to the virtual machine, it must be made visible to the Microsoft Windows operating system. Power on the virtual machine and follow the next steps to initialize the secondary disk.
In Windows, click the
Start button and select the
Control Panel entry in the shown dialog.

Once the
Control Panel is launched, select
Performance and Maintenance,
Administrative Tools and launch the
Computer Management applet. There are other ways to launch the
Management Console, but the described one always works (even if no desktop icons are shown).
A much simpler way is to
right-click on the
My Computer icon on your Windows desktop and select the
Manage menu item. Unfortunately, all desktop icons except the Trash are hidden in the default installation of Windows XP. Unhiding these icons is discussed n the
Customize XP section in
this tutorial.

In the left pane of the graphical user interface, select the
Storage / Disk Management option. The
Initialize and Convert Disk Wizard pops up and safely follow the wizard with the default options to initialize the new disk in basic format.

If you canceled the wizard, the initialization is done by right-clicking on the area with the
Not initialized disk state notification.
Once the disk is initialized for Windows, a new partition needs to be created.
Right-click on the
unallocated region of the new disk and click the
New Partition menu to launch the
New Partition wizard.

The easiest way is to create a new
primary partition and
use all available space for the new partition. A maximum of 4 primary partitions is allowed, otherwise you need to use extended partitions.

Also keep care to
assign a drive letter to the newly created partition. In this tutorial, I choose the
drive letter W (for work), but they can easily be changed in the GUI after the partition is created.
The partition needs to be formated with a filesystem before files can be stored. The preferred filesystem in newer Windows versions is NTFS. Another common choice is FAT32 because it can be read by any other operating system.

The secondary disk is now visible and accessible in Windows and can be used to store information.
In the next section of this tutorial, a change is made to move all existing files in the
My Documents folder to this new partition. A nice side effect is that all applications reading and writing by default to the
My Documents folder will be redirected to the new location.
