My DVD drive has buggered up so I need to replace it with a spare.. I know how to insert the drive into the tower and connect all cables, but is there a proccess i go through once my comptuer is running to activate or get the drive to run?
Open up your case, and then look for one of the following cables.
IDE uses a ribbon cable to connect the drive to the motherboard. It is very thin and wide, like this:
A SATA drive uses a cable like below:
If you have spare SATA ports on your motherboard, you could upgrade to a SATA optical drive if you currently use a IDE one with the ribbon cable. If you are upgrading to SATA, make sure your power supply has a spare SATA power connector, or order up a Molex-to-SATA power connector to connect it using an existing Molex connector as used by the IDE drives.
SATA ports on a motherboard (blueish in the picture) look like below.
Though the colours can vary, so just make sure they look physically the same.
