Drives

Your computer supports:

• Two serial ATA hard drives
  
  
• Two floppy or optional Zip drives
  
  
• Two CD or DVD drives
  
  

NOTE: Due to the limited number of drive bays and IDE controllers on this computer, you will not be able to connect all supported devices at once.

1	CD/DVD drive
2	floppy drive
3	hard drive

General Installation Guidelines

Connect CD/DVD drives to the connector labeled "IDE" on the system board. Serial ATA hard drives should be connected to the connectors labeled "SATA0" or "SATA2" on the system board.

IDE Drive Addressing

When you connect two IDE devices to a single IDE 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). See the drive documentation in your upgrade kit for information on configuring devices for the cable select setting.

Connecting Drive Cables

When you install a drive, you connect two cables—a DC power cable and a data cable—to the back of the drive and to the system board.

Drive Interface Connectors

IDE Drive Connector	Serial ATA Connector

1	colored stripe on IDE cable
2	interface cable connector
3	interface connector

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 stripe along one edge of the IDE cable—serial ATA cables do not use a colored stripe) 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 IDE interface cable, do not place the colored stripe away from pin 1 of the connector. Reversing the cable prevents the drive from operating and could damage the controller, the drive, or both.

Power Cable Connectors

IDE Drive Power Connector	Serial ATA Power Connector

1	power cable
2	power input connector

Connecting and Disconnecting Drive Cables

When removing an IDE drive data cable, grasp the colored pull-tab and pull until the connector detaches.

When connecting and disconnecting a serial ATA data cable, hold the cable by the black connector at each end.

Like IDE connectors, the serial ATA 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.

Hard Drive

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.

CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before removing the computer cover.

NOTICE: To avoid damage to the drive, do not set it on a hard surface. Instead, set the drive on a surface, such as a foam pad, that will sufficiently cushion it.

Removing a Hard Drive

1. If you are replacing a hard drive that contains data you want to keep, back up your files before you begin this procedure.
   
   
2. Check the documentation for the drive to verify that it is configured for your computer.
   
   
3. Follow the procedures in "Before You Begin."
   
   
4. Disconnect the power and hard-drive cables from the drive. Disconnect the hard-drive cable from the system board.
   
   

1	hard-drive cable
2	hard-drive cable on system board

5. Press in on the blue release tabs on each side of the drive and slide the drive up and out of the computer.
   
   

Installing a Hard Drive

1. Unpack the replacement hard drive, and prepare it for installation.
   
   
2. Check the documentation for the drive to verify that it is configured for your computer.
   
   

NOTE: If your replacement hard drive does not have the plastic hard-drive bracket attached, remove the bracket from the existing drive by unsnapping it from the drive. Snap the bracket onto the new drive.

3. Gently slide the hard drive into the hard-drive bracket until it clicks into place.
   
   

4. Gently slide the hard drive into the drive bay until it clicks into place.
   
   
5. Connect the power and hard-drive cables to the drive. Connect the hard-drive cable to the connector on the system board.
   
   
6. Check all connectors to be certain that they are properly cabled and firmly seated.
   
   
7. Replace the computer cover.
   
   
8. If the drive you just installed is the primary drive, insert a bootable medium into your boot drive. See the documentation that came with the drive for instructions on installing any software required for drive operation.
   
   
9. Enter system setup and update the appropriate Primary Drive option (0 or 1).
   
   
10. Exit system setup, and reboot the computer.
    
    
11. Partition and logically format your drive before you proceed to the next step.
    
    

See the documentation for your operating system for instructions.

12. Test the hard drive by running the Dell Diagnostics.
    
    
13. If the drive you just installed is the primary drive, install your operating system on the hard drive.
    
    

Adding a Second Hard Drive
