Hard-disk initialization
CAUTION A hard-disk initialization erases and reformats the device hard disk. Perform a hard-
disk initialization only if an error code on the control panel indicates an EIO disk error. Always try
initializing the hard disk before replacing it.
NOTE Before performing a hard-disk initialization, print a menu map and a configuration page
(see
Use information pages on page 38). Use the information on the configuration page to reset
any customer-set device configuration values that the hard-disk initialization procedure changes.
1. Turn the device off.
2. Turn the device on. When the memory count begins, press and hold the Menu button. Continue
holding down the Menu button until all three device control-panel lights flash once and then remain
on. This might take up to 10 seconds.
3. Press the
button. The display should show INITIALIZE DISK.
4. Press
. The device initializes the hard disk and continues the power-on sequence.
Skip disk-load
When the power is turned on the device begins the power-on sequence. By performing a power-on
bypass, you can cause the device to resume the power-on sequence but not to recognize any installed
EIO hard disk. This can be helpful in isolating EIO hard-disk errors.
1. Turn the device off.
2. Turn the device on. When the memory count begins, press and hold the

Self test
This procedure is a remnant of previous products and no longer provides a test of the device.
Service menu (service PIN codes)
Authorized HP service technicians can use this menu to gain access to device settings that are reserved
for service personnel. The SERVICE menu is protected by use of a personal identification number (PIN).
When you select SERVICE from the list of menus, you are prompted to type an eight-digit PIN code.
NOTE The device automatically exits the SERVICE menu after about one minute if no menu
items are selected or changed.
