Setting up Master and Slave

I spy a basic misunderstanding. Your primary master device (the Samsung 10GB hard 
disk) plays no part in the recognition of a second hard disk as slave device on the 
primary IDE cable.

Recognition is handled by the motherboard electronics, and you control the process 
by entering the BIOS screen on start-up (press DEL) and then using the BIOS's auto-detect 
function.

Every modern BIOS program includes an ability to auto-detect the correct settings, 
which it reads from the hard disk, but you have to enter the BIOS program screen 
and trigger the detection routine. Until you do, the slave device won't be recognised.

Before attempting this, you must set the jumper switch on the master device to MASTER, 
and the jumper on the slave device to SLAVE. The correct settings will be printed 
on a label pasted to the casing of each disk. Also, the Master device must be attached 
to the black IDE connector, and the slave device to the grey IDE connector.


Anti-Static Precautions

Take proper anti-static precautions before touching anything inside the computer, 
to avoid static electrical damage to the delicate electronics inside.

You need to follow some simple guidelines:

1. Shut down the computer, and SWITCH OFF the mains power at the wall socket. This 
is an ESSENTIAL safety precaution!

2. If the computer has a 3-pin mains plug, DON'T unplug the computer from the wall 
socket. The 3rd pin is an Earth connector, which grounds the chassis (the metal case) 
of the computer; you need to leave that connected. Any dangerous voltages are INSIDE 
the (sealed) power supply unit, where you can't get at them.

3. Immediately before touching anything inside the computer, touch an unpainted bare 
metal part of the chassis (the casing) with your bare hand. The metal casing is connected 
to earth (through the wall socket), so your body is thereby earthed, draining any 
static electricity from your body: half a second and it's gone. Do this every time, 
because as you move about the contact with carpets and clothing will generate further 
static electricity on the surface of your body.

4. If you use a tool (e.g. a screwdriver, or vacuum cleaner), touch a bare metal 
part of the tool to the bare metal of the computer's casing before you touch it to 
anything inside the computer.

5. If your computer does not have a 3-pin mains plug (i.e. it has a 2-pin plug), 
earth yourself by touching unpainted bare metal on a central heating radiator pipe 
or cold water pipe instead, as those are normally connected to ground. Do this for 
yourself and for your tools.

6. Don't let any part of your clothing touch anything inside the computer, as clothes 
can carry a large static electrical charge. It is therefore best to roll your sleeves 
up.

7. While working inside the computer don't scuff around on the carpet, or slide in 
and out of a chair - as this will cause a build up of static electricity.

8. You must also apply these precautions when handling any component that you unplug 
from the computer: such as a hard disk, or a PCI card, or a RAM memory module.

NB: The safest procedure is to rest your bare forearm on an unpainted bare metal 
part of the casing continuously whilst working inside the computer, thereby leaving 
both your hands free.
