Adding a Second Hard Drive to a System With a
Single Optical Drive and ZIP Drive
The small form-factor and small desktop systems support a single enhanced integrated
drive electronics (EIDE) hard drive in the hard drive bay; the small mini-tower system
supports two EIDE hard drives.
All EIDE devices require that you configure the cable select setting, which assigns
master and slave status to devices according to their position on the interface cable. You
usually configure a drive for cable select by setting a jumper or switch, depending on the
drive. Refer to the drive documentation in your upgrade kit for information on configuring
devices for the cable select setting. When you connect two EIDE devices to a single EIDE
interface cable and configure them for the cable select setting, the device attached to
the last connector on the interface cable is the master or boot device (drive 0), and the
device attached to the middle connector on the interface cable is the slave device (drive
1).
With the two EIDE interface connectors on the system board, your system supports up to
two EIDE devices. EIDE hard drives should be connected to the EIDE interface connector
labeled "IDE1." (Always connect CD-ROM drives to the EIDE interface connector
labeled "IDE2.")
When you install a drive, you connect two cables—a DC power cable and an interface
cable—to the back of the drive. Your drive’s power input connector (to which you
connect the DC power cable) resembles the following connector.

The drive’s interface connector is a card-edge connector or a header connector, as
shown in the following figure.

Interface Connectors

|
When you attach the interface cable to a drive, be sure to match the colored strip on
the cable to pin 1 of the drive’s interface connector. For the location of pin 1 on
the drive’s interface connector, see the documentation that came with the drive.
When you disconnect an interface cable from the system board, be sure to press in on
the locking tabs on the cable connector before you disconnect the cable. When you attach
an interface cable to the system board, be sure that the locking tabs snap into place so
that the cable is firmly attached to the connector on the system board.
Most interface connectors are keyed for correct insertion; that is, a notch or a
missing pin on one connector matches a tab or a filled-in hole on the other connector.
Keyed connectors ensure that the pin-1 wire in the cable (indicated by the colored strip
along one edge of the cable) goes to the pin-1 end of the connector. The pin-1 end of a
connector on a board or a card is usually indicated by a silk-screened "1"
printed directly on the board or card.
NOTICE: When you connect an interface cable, do not reverse
the interface cable (do not place the colored strip away from pin 1 of the connector).
Reversing the cable prevents the drive from operating and could damage the controller, the
drive, or both.
|
CAUTION: To avoid the possibility of
electric shock, turn off the computer and any peripherals, disconnect them from electrical
outlets, and then wait at least 5 seconds before you open the computer cover. Also, before
you install a drive, see the other precautions in "Safety Information." |
- If you are replacing a hard drive that contains data you want to keep, be sure to make a
backup of your files before you begin this procedure.
NOTICE: Ground yourself by touching an unpainted metal
surface on the back of the chassis.
NOTICE: When you unpack the drive, do not set it on a hard
surface, which may damage the drive. Instead, set the drive on a surface, such as a foam
pad, that will sufficiently cushion it.
- Unpack the drive, and prepare it for installation.
Check the documentation for the drive to verify that it is configured for your system.
Open the computer cover.
On the small desktop system, remove the plastic shroud covering the hard drive by
pressing in on the indented tab at the top of the shroud and lifting the shroud away.

- Disconnect the power and interface cables from the drive.
- For the small form-factor system, press in on the tabs on each side of the bracket and
slide it toward the I/O panel and remove the drive from the chassis.
For the small desktop and small mini-tower system, press in on the tabs on each
side of the bracket, and slide it up and out.
- If your replacement hard drive does not have the bracket rails attached, remove the four
screws holding the bracket rails to the hard drive.
NOTICE: To avoid possibly damaging the drive by ESD, ground
yourself by touching an unpainted metal surface on the back of the chassis.
NOTICE: When you unpack the drive, do not set it on a hard surface, which may damage
the drive. Instead, set the drive on a surface, such as a foam pad, that will sufficiently
cushion it.
- If necessary, attach the bracket rails to the new hard drive by aligning the four screw
holes of the drive and bracket and then inserting and tightening the screws that came with
your upgrade kit.
- Reinstall the hard-drive bracket in the chassis by gently sliding the bracket into place
until you hear it securely click.
- Connect a power cable to the power input connector on the back of the drive, and connect
one of the device connectors on the EIDE cable to the 40-pin interface connector on the
back of the hard drive.
- Check all connectors to be certain that they are properly cabled and firmly seated.
- On the small desktop system, replace the hard-drive shroud.
NOTICE: To avoid possible damage to the system, you must match
the colored stripe on the EIDE interface cable with pin 1 on the drive's interface
connector and with the EIDE interface connector (labeled IDE1) on the system board.
To locate EIDE connector 1 (IDE1) on the system board, see "System Board Components."

- Close the computer cover.
- If the drive you just installed is the primary drive, insert a bootable system diskette
into the diskette drive.
- Turn on the computer.
- Enter system setup and update the appropriate Primary Drive option, 0 or 1.
See " System Settings"
for complete information on system setup.
Reset the chassis intrusion
detector.
Restart the system.
Partition and logically format the system's hard drive before proceeding to the next
step.
For partition and format instructions, refer to the documentation that came with the
operating system.
| |
NOTE: On systems with hard drives
larger than 2 GB, create a primary partition of 2 GB and divide the remaining capacity
into partitions of 2 GB or less. For example, a system with a 2.5-GB hard drive would have
a primary partition of 2 GB (drive C) and a second partition of 500 MB (drive D). Hard
drives must be partitioned this way because MS-DOS®—based operating systems
(including Microsoft® Windows NT®, when using a FAT16 file system) do not support drive
partitions larger than 2 GB. |
- Test the hard drive by running the Dell Diagnostics.
See " Solving Problems" for
complete information.
If the drive you just installed is the primary drive, install the operating system on
the hard drive.
For instructions, refer to the documentation that came with the operating system.
