As I mentioned in the introduction, repair of components is not economically
viable. A really observant and talented individual could repair a failed cd rom,
if it was a mechanical failure. Or if you had two of the same model drives, one
that failed electronically and one that failed mechanically, you could change
out the bad circuit board on the mechanical failed drive for the good circuit
board and save your self thirty dollars. Or you could go buy a brand new one and
replace it.
Before you loosen up the drive you should disconnect the power cable, the drive
cable, and the Audio cable. If you can not get your hand into the space to
disconnect the cables pull the drive carefully out until you can gripe the
cables. Usually the IDE Drive Cable will pull loose with a little force, there
is a latch on the Audio cable. The cable that will give you problems is the
power cable, they are made to not vibrate loose. You can use a pair of pliers to
wiggle it loose, do not squeeze it to hard, it is plastic and will break, with a
firm grip on the plug, working it back and forth while pulling gently will get it
loose.
Note the wide cable, it is the IDE Connection cable, it will have a red stripe
down one side. This indicates the # 1 pin side of the cable connector. Some
cables that have been in the computer for a long time tend to harden from time
and heat, you should not have to change the routing of the cable. Some cable
connectors have a guide pin that will match the connector on the drive, this
keeps you from connecting the cable backwards, some don't that is why you have
to note the stripe. Look at both drives, the IDE cable connector should be
orientated the same, note the notch for the cable in the connector on the drive,
are they both orientated the same or are they opposite? If they are opposite
then you will have to reorient the IDE cable before you install the drive.
Look at the back of the drive, next to the cable connectors there should be a
double row of small brass pins. These pins are called jumper pins. You will see
one or two small plastic covers (called Jumpers) over some of the pins. On the
drive there should be a diagram that will tell you what the covered pins do,
this is the drive selection.
Your choices for the drive selection are:
Master
Slave
Cable select
Set the old drive aside, check the new drive, you need to match the drive select
pin setting on the new drive to what the old drive has. Either Master (two
drives on same cable and this is the primary drive), Slave (two drives on the
same cable and this is the secondary drive), or Cable Select (best selection for
a single drive on a cable).
Once you have the drive selection set, reverse the removal sequence to install
the drive. Once you have the cables reconnected and the drive back in it's bay
put the cover back on the computer. I do not recommend powering up the computer
with the cover off.
Check the drive:
When you power up the drive the startup sequence checks all drives, you should
see the cd drive activity light come on, push the drive eject button, the tray
should open if not, power the system down, you have a problem. (go to trouble
shooting)
If you have power to the drive let the computer power up, put a cd in the drive,
see if you can access the drive. Access?
mechanical failure. Or if you had two of the same model drives, one
that failed electronically and one that failed mechanically, you could change
out the bad circuit board on the mechanical failed drive for the good circuit
board and save your self thirty dollars. Or you could go buy a brand new one and
replace it.
