Hard Drive Care and Handling

There is one hard drive option for the GoBook II: a removable shock-mounted 2.5-inch hard

drive. All hard drives contain media for data storage in the form of a rotating disk, read/write

head(s), a motor, and electronics for interfacing and control. Drives can be susceptible to damage

from severe shock and other stressful environmental impacts. The degree of susceptibility to

damage is directly related to the individual hard drive and the mounting system employed.

When reading or writing to the hard disk , the head is “flying” on a thin layer of air, micro-inches

above the disk. A shock can cause the read/write head to contact the spinning disk, resulting in

immediate loss of stored data and possible physical damage to the disk. It could also create loose

debris in the drive enclosure that may cause progressive damage over time.

To reduce exposure to high operating shocks, the GoBook II uses power modes for the hard drive

that prevent the read/write heads from being positioned over the disk when it is not being used:

idle mode and standby mode.

You can reduce the risk of damage to the hard drive and increase the reliability of the hard drive

and data integrity by following the recommendations below.

Installing and Removing the Hard Drive

To remove the hard drive:

1. Shut down the unit and remove external power.

2. Open the battery door and remove the battery using the extraction tape. The hard drive is in

a cassette that can be seen in the batter

well

ust under the RTC hatch.
