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 battery well just under the RTC hatch.
