2HDD system (optional)
When the device ships, the second hard disk is connected to SATA port 2. This hard disk
drive is not set up. This gives you the option of backing up your data to this hard disk. For
information on hard disk capacities, refer to your order documentation.
Booting from the slave hard disk
In order to allow booting from the second hard disk, you need to configure it as the primary
boot device. Make the following settings in your BIOS Setup:
Select Boot > Hard Drive > <Disk name> e.g. STxxxxxxxxx- SATA2, then press the "+" key
to move it up in the boot order.
NOTICE
The drive letters for the partitions on both drives are assigned by the operating system
used. You can change these in the Control Panel as required.
