Fitting the Hard Disk Drive This page assumes you are fitting a EIDE rather than a SCSI-totally different procedure!. Take the Hard Disk Drive (HDD) out of the box. At this point it is perhaps a good idea to mention anti static measures. Make sure at this stage that you have your anti-static measures in place, and even briefly make contact with both hands on the metal of the case to make sure.
Locate the IDE Configuration Pins on the HDD. These can usually be found next to the power and data connections, and will be a group of six or eight small pins with a small plastic 'jumper' attached between two of the pins. If this is to be the only HDD in your PC, then set this to Master. (You NEED a manual-or a good supplier website) Alternatively, if this is to be an additional Hard Disk Drive (your second HDD and the first is already set to master) then it must be set to Slave.

On one end of the Hard Drive will be the sockets for connecting the cables (EIDE etc). This end must point into the case making it easy to connect the cables later on. Gently slide the Hard Drive into the bay that now holds the floppy drive (which can be above or below-most commonly the floppy is below). Move the drive around until you find the fixing points and use the standard screws to secure it to the drive bay. Then secure the drive bay to the case by using the coarse-threaded screws.

Never carry out any work on your computer whilst is is plugged into the mains power socket, you could cause yourself and your PC damage.

The power supply does not contain any user servicable parts and contains hazardous voltages it should not be opened-even after it has been switched off.

Many desktop and tower cases have sharp edges be careful when working inside the case of your PC.
