0When you have finished accessing your drives, see the instructions in Chapter 5 to replace the subassembly and the computer’s cover.
Additional instructions in each section tell you which steps to perform next.
Setting the Hard Disk Drive Jumpers
You need to check or change the hard disk drive jumper settings if you install or remove any hard disk drives. The jumpers on the drive tell the computer whether you are using one hard disk drive or two.
Note
You do not need to set these jumpers if you are removing your only hard disk drive.
If you remove one hard disk drive and leave another in your computer, you need to change the jumper settings on the remaining drive to indicate that you now have only one hard disk drive installed.
If you are installing your first hard disk drive and it is the only one you are going to install, see “Changing the Jumper Settings” on the next page to check the jumpers on your drive.
If you’ll be using two hard disk drives, see “Setting the Jumpers for Two Hard Disk Drives,” below.
Setting the Jumpers for Two Hard Disk Drives
If you install two hard disk drives in your system, you must change the jumper settings on each drive to indicate which drive is the umastern drive and which is the "slaven drive.
