4. Check all connectors to be certain that they are properly cabled and firmly seated.
   
   

NOTICE: To avoid possible damage to the computer, you must match the colored stripe on the hard-drive data cable with pin 1 on the hard-drive (IDE1) connector and with the system board interface connector (IDE1).

To locate the system board interface connector (IDE1), see "System Board Components."

5. If the drive you just installed is the primary drive, insert a bootable floppy disk into the floppy drive.
   
   
6. Turn on the computer.
   
   
7. Enter system setup and update the appropriate Primary Drive option, 0 or 1.
   
   

See the User's Guide for complete information on system setup.

8. Reset the chassis intrusion detector.
   
   
9. Restart the computer.
   
   
10. Partition and logically format the computer's hard drive before proceeding to the next step.
    
    

For partition and format instructions, see the documentation that came with the operating system.

11. Test the hard drive by running the Dell Diagnostics.
    
    

See "Solving Problems" in the User's Guide for complete information.

12. If the drive you just installed is the primary drive, install the operating system on the hard drive.
    
    

For instructions, see the documentation that came with the operating system.

Adding a Second Hard Drive — Small Mini-Tower Computer

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.

5. Attach the rails to the hard drive using the two screws attached to the rails.
   
   

Ensure that the rail tabs are positioned at the back of the hard drive.

NOTICE: Do not install a drive into the lower hard-drive bay until you remove the green drive rails from inside the lower hard-drive bay.

6. Remove the first hard drive from the upper bay and install it in the lower bay.
   
   
   1. Disconnect the power cable and the data cable from the back of the first hard drive.
      
      
   2. Press in the two green rail tabs and pull the first hard drive out of the upper bay.
      
      
   3. Gently slide the first hard drive into the lower bay until you hear a click.
      
      
   4. Reconnect the power cable and the data cable to the back of the hard drive.
      
      
7. Gently slide the new hard drive into the upper bay until you hear a click.
