Hard Disk Drive Problems

A newly-installed

hard

disk drive is not working property or

its performance is not what you expect.

Make sure you have installed the drive correctly and check all
cable connections. Also, check the jumper settings on your
drive.

Check that you have installed the IDE driver on your hard disk

(see Chapter 2). To take advantage of the local bus IDE

interface, your hard disk drive must support a 32-bit data path
that uses double-word I/O. Also make sure your CONFIG.SYS
file is loading the IDE driver when you start your system.

Some hard disk drives do not support the Energy Star features
on your system. You may need to disable these features in
SETUP.
