Dell™ OptiPlex™ 760 Service Manual

  Drives

Drives

Your computer supports:

• One SATA (serial ATA) hard drive
  
  
• One optional Dell D-module optical drive, second hard drive, or floppy drive in the module bay (see Module Bay for information on installing and removing devices in the module bay).
  
  

General Installation Guidelines

NOTE: For information on installing D-module drives, see the documentation that came with your optional device.

Connecting Drive Cables

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

Connecting and Disconnecting Drive Cables

When connecting and disconnecting a SATA data cable, hold the cable by the black connector at each end. When removing a cable with a pull-tab, grasp the colored pull-tab and pull until the connector detaches.

Hard Drive

WARNING: Before working inside your computer, read the safety information that shipped with your computer. For additional safety best practices information, see the Regulatory Compliance Homepage at www.dell.com/regulatory_compliance.

WARNING: To guard against electrical shock, always unplug your computer from the power supply before removing the hard drive.

CAUTION: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your computer's electronic components. You can do so by touching an unpainted metal surface on the computer chassis.

CAUTION: 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 the Hard Drive

1. Follow the procedures in Working on Your Computer.
   
   
2. Remove the computer cover (see Removing the Computer Cover).
   
   
3. Disconnect the power and data cables from the hard drive.
   
   
4. Press the plastic drive rails towards each other and slide the drive slightly forward.
   
   
5. Rotate the hard drive up and away from the computer.

Installing a Hard Drive

1. Follow the procedures in Working on Your Computer.
   
   
2. Remove the computer cover (see Removing the Computer Cover).
   
   
3. If you are installing a new drive, rather than replacing an already installed drive:
   
   
   1. Check the documentation for the drive to verify that the drive is configured for your computer.
      
      
   2. Attach the plastic drive rails—located inside the cover—to the new drive and skip to step 6.

CAUTION: If you are replacing a hard drive that contains data you want to keep, back up your files before you begin this procedure.

4. Remove the installed hard drive (see Removing the Hard Drive).
   
   
5. Remove the four screws that secure the drive rails to the existing hard drive, and attach the drive rails to the replacement hard drive.
   
   

CAUTION: Serial ATA data and power 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. When connecting cables to a drive, ensure that the connectors are oriented properly before you attach the cables to the drive.

6. Slide the hard drive into the hard drive bracket.
   
   
7. Attach the data and power cables to the hard drive connectors, ensuring that the connectors are properly oriented before connecting them.
   
   

8. Replace the computer cover (see Replacing the Computer Cover).
   
   
9. Replace the cable cover, if used.
   
   
10. See the documentation that came with the drive for instructions on installing any software required for drive operation.
    
    
11. Reboot the computer.
    
    
12. Partition and logically format your drive before you proceed to the next step.
    
    

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

13. Test the hard drive by running the Dell Diagnostics (see Dell Diagnostics).
    
    
14. Install your operating system on the hard drive.
    
    

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