If you are installing a new hard drive that does not have a plastic case, you can remove the case from the old hard drive: · Remove the four screws from the sides of the case. · Remove the top shield from the drive and swing out the free end of the hard drive about 90°, then gently pry off the connector from the hard drive. The OmniBook 3000 may not have a top shield.
Caution: For a Toshiba drive, make sure the HDD case has a metal top shield. Caution: The top shield for a 9.5-mm drive has spacers.

HDD Case (Kit) (includes M3×5mm screws)

Figure 2-4. Installing a Hard Drive in the Case Reassembly Notes

Caution
· Use a HDD case kit that is compatible with the thickness of the drive, 9.5 mm or 12.7 mm. The 9.5-mm drive requires spacers inside the top shield. · Install the metal top shield that is included with the HDD case. If an older HDD case does not have a top shield, you must install a newer HDD case if the drive is a Toshiba drive-- otherwise, drive performance may be reduced by magnetic interference. · Do not cover the vent hole in the top surface of the hard drive or in the case. If you cover the hole, the hard drive could fail prematurely.

· Depending on the manufacturer of the replacement drive, the hole placement for the four screws may vary.
Important If you are installing a new hard drive, you should create a Hibernate partition on the drive before loading any software--see the steps below. Creating a Hibernate Partition

1. If you do not have an OmniBook Recovery CD and internal CD-ROM module for the computer model you are repairing, create a Support Utility floppy disk now. After inserting a formatted floppy disk in the floppy drive, do one of the following:

¨ On a factory software installation, click Start, Programs, OmniBook, Create Support Utility Disk.

2-6

Removal and Replacement

HP OmniBook 2100/3000/3100

¨ On any computer that has a CD-ROM drive, run makesupp from the \Omnibook\Drivers\Hputils directory on the OmniBook Recovery CD. ¨ On any computer with World Wide Web access, download the Support Utility software package from the OmniBook website (see page vi). Follow the instructions provided.
2. Insert the Recovery CD in the CD-ROM drive--or insert the Support Utility disk in the floppy drive. 3. Reboot the computer. If you are using the Recovery CD, press ESC during reboot if the OmniBook screen appears, ESC to display the boot-device menu, then select the CD-ROM drive as the boot device. 4. When prompted, select "Create Hibernate Partition."
