4 Using the Notebook PC Second Hard Disk Drive Module (Optional) The convenient design of the Notebook PC allows for the usage of a second hard disk drive in the modular bay. A second hard disk drive allows you to use it as a removable device, for installing dual operating systems, for additional data storage, or to store CDs. To use a second hard disk drive, you must be familiar with the following: • What to purchase and the contents of the kit. • Setting up, partitioning, formatting, and using the second hard disk drive. Purchasing the Second Hard Disk Drive Module Contact your retailer for a Notebook PC second hard disk drive kit specific for your Notebook PC; others will not work. The kit should only contain an empty module so a hard disk drive must be purchased separately. Select a 0.95cm thick EIDE hard disk drive with the capacity that you require. Current capacities that are within 0.95cm are between 5GB and 40GB. Larger capacities will follow soon. Typical hard disk drives of this size have a rotation speed of 4,200RPM compared with desktops of 4,500-10,000RPM but seek time is less because of the smaller size. Less RPM decreases noise, heat, and energy consumption. This Notebook PC supports interfaces up to UltraDMA Mode 5 (also known as UltraDMA/100 or ATA100). A hard disk drive connected via the external expansion port only supports UltraDMA/33 (ATA33). Using New Hard Disk Drives The AiBox connects to an independent IDE channel on this Notebook PC and therefore no jumper settings are necessary. For other Notebook PCs, you may have to place a jumper on the pins as indicated on the hard disk drive to set it as "DEVICE1" or "SLAVE" so that it will not conflict with the first hard disk drive. The first hard disk drive in the Notebook PC should not have any jumpers on it so that it can be used as "DEVICE0" or "MASTER". If two hard disk drives have the same setting, you may get a message "Operating System not found" due to the hardware conflict. If properly configured, bootup will display both hard disk drives and their physical capacity. Upgrading Hard Disk Drives Using a third-party utility, you can copy an entire hard disk drive to a second hard disk drive, and then set the new partition active. 46
