To add a virtual hard disk drive to a virtual machine, the user can choose to add an existing disk image file or create a new blank disk image. The user then selects the disk type as IDE or SCSI, chooses the disk size and format, and specifies the disk image file location. Certain guest operating systems may require additional drivers to support the SCSI controller. Newly added blank disks also need to be initialized before use.

1. Adding a Virtual Hard Disk Drive
You can add to your virtual machine an existing hard disk image or create a new, blank one.
Note: A virtual machine can have up to four IDE devices (hard disks or CD/DVD-ROM drives) and 15 SCSI devices
(hard disks or CD/DVD-ROM drives).
To add a hard disk to a virtual machine
1. Choose Configure from the Virtual Machine menu to open Virtual Machine Configuration.
2. Click the Add button in the bottom part of the Virtual Machine Configuration dialog to launch
Add Hardware Assistant.
3. In the Select Device window, select Hard Disk and click Continue.
To add a hard disk that will have a typical configuration, choose the Hard Disk icon and click the Add
Typical Device button. Assistant will create a typical hard disk ready for use.
Note: A typical virtual hard disk is in the expanding format and its capacity is 32 GB.
4. In the Add Hard Disk window, select the resource for the new virtual hard disk and
click Continue. You can choose one of the following options:
 New image file. In this case, the assistant will create a new image that will emulate the
hard disk.
 Existing image file. In this case, an existing image file will be added to the virtual
machine and used to emulate the hard disk. If you selected this option, go to Step 8.
 Boot Camp partition. In this case, Boot Camp partition will be added as a hard disk to
your virtual machine. If the virtual machine doesn't have any hard disk, Boot Camp is added as
[0,0] disk. If there is already a virtual disk, Boot Camp will be added as a data disk. For more
information on adding a Boot Camp partition to a virtual machine, see the Using the Boot Camp
Partition in a Virtual Machine chapter. Click Finish.
5. If you selected the New image option, on the next step you will need to set the virtual hard disk
size in the Size field and define its format. You can choose one of the following formats for the
disk: Expanding or Plain. If you want the virtual hard disk to be splitted, select the Split the hard disk
image into 2 GB files option. For more information on hard disk formats, refer to Support of Virtual and
Real Disks.

2. When you are ready, click Continue.
6. In the next window, you can configure the location of the hard disk image file and specify its
interface type.You can choose one of the following interface types for the disk:
 If you select the IDE option, you will be able to define the IDE device identifier in
the Location list.
 If you select the SCSI option, you will be able to select the SCSI device identifier in
the Location list.
Note: The SCSI 7:0 location is not available for selecting, since it is occupied by the SCSI
controller itself.

3. 7.
8. Note: 1. The Mac OS X guest OS does not support the SCSI controller.
9. 2. In the latest Linux distributions (e.g. RHEL 5.3), the SCSI driver may be not installed. In this
case, you should install this driver in your Linux guest OS to be able to use the SCSI controller.
10. Click Add Device to add a new hard disk to the virtual machine.
11. If you selected the Existing image file option on Step 5, in the Add Hard Disk window you will
need to specify the full path to the image file you wish to use in your virtual machine. You can type the
path manually or use theChoose button to locate the image file.
If you added a new blank virtual hard disk, you need to initialize it before you can use it. For more information
about initializing the newly added disk, see Initializing the Newly Added Disk.
If you added an existing disk, make sure that its file system is compatible with the guest OS installed in the virtual
machine.
