Hi alba, welcome to the forum.
Installing a new drive into your computer is a pretty straightforward job. Open up your computer case and take a look at how your current DVD-ROM is attached to your computer. Generally speaking a computer has two so-called IDE controllers. You can identify these by following the big (often grey) flat cable that is attached to your hard disk(s) and DVD-ROM drive. They will lead down to your motherboard. Note: your hard disk is always attached to the primary IDE port on your motherboard, optical drives should be located on the secondary IDE port.
You will probably have one of these two situations:
- Your DVD-ROM drive and hard disk are attached to the same cable.
- Your hard disk is attached to a seperate cable and so is your DVD-ROM.
If the second scenario is the case then take out the DVD-ROM drive and the flat cable. In general it’s best to set the CD-RW burner to master and the DVD-ROM to slave device. In IDE systems there is always a Master device and a Slave device. The settings of the drive are controlled via small so-called jumpers on the back of the drive. These a small plastic clips that fit over two metal pins. The master and slave settings can be found on the lable on top of the drive or on the back of the drive.
Set your CD-RW to Master and your DVD-ROM to slave. Build in both drives and re-attach the flatcable. The master device should be the last device on the cable. Often it will also work if you set the master drive before the slave drive but it’s recommended to us this:
Motherboard - Slave - Master
Now turn your computer back on and see if the devices are recognized correctly. If they are then you’re done. When Windows XP loads you should check the Device Manager (Control Panel -> System) and check the Secondary IDE channel properties. For best performance both devices should be using UDMA mode 2 (provided of course that both drives supports this but all modern drives do).
Please report back if you need more help.
