powered on
♦ The removable HDD(s) have activity LEDS

will come on when power is applied. After a few
moments the BIOS and Windows operating system
messages and graphics will appear.
⇒ If the system does not power on, ensure that you
have batteries with at least 30% charge, or that the

HDD Usage
Using the removable hard disk drives
The right side of the D310 has a 2.5” removable
drive bay. This bay has two separate hard drives
inside it. The drive marked (1) is the C drive, and
the drive marked (2) is the D drive.
⇒ NEVER REMOVE OR INSTALL HARD DRIVES WHEN
THE SYSTEM IS POWERED ON. Interfering with the
C drive in particular when the software is trying to
access it can cause catastrophic system failures via
corrupting the le system.
To remove either hard drive, you must have access
to the keylock. Turn the key into the lock and then
press the button on either drive to eject it. To insert
another drive, reverse these steps.
Using external optical read/write drives
Because the D310 does not include an optical drive,
you are free to purchase one from any computer
retailer, and connect it to your D310 via one of the
USB 2.0 ports.
- The D310 is compatible with external optical drives
which are Windows7 compatible.
The 2.5” drive carrier actually has TWO separate removable
HDDs inside! Drive 1 is the OS drive letter ‘C,’ while Drive 2
is the data drive letter ‘D.’
