Hard Disk Drive Problems
A newly-installed hard disk drive is not working properly or
its performance is not what you expect.
Make sure you have installed the drive correctly and check all
cable connections. Also, check the drive’s jumper settings.
You see a hard disk drive error when you start your system.
Run SETUP and check that your system is auto-sensing the
correct drive type. If auto-sensing is enabled and SETUP
displays information that does not match your drive, you may
need to define your own drive type. See Chapter 2 for setup
information.
Make sure the jumpers on the system board are set correctly
Jumper 523 enables or disables the IDE hard disk drive
controller. See Chapter 4 for jumper information.
Make sure the jumpers on the hard disk drive are set correctly.
See your hard disk drive documentation for more information.
You ate unable to state data on the hard disk drive.
If your drive was not configured, make sure you have
partitioned and formatted it correctly for your operating
system. See your operating system manual for instructions.
Also, make sure your hard disk drive has been physically
formatted by the manufacturer. (All EPSON-supplied drives
are physically formatted at the factory.) If it has not been
physically formatted, use the format utility that came with the
drive to format it before you install the operating system.
Note that a physical format is different from software-based
formatting commands, such as the MS-DOS FORMAT
command.
