|That drive is an IDE ATA drive. That type of drive has jumpers on the back end of the drive. There is a corresponding label on the top that shows which pins are for which setting.|
When using TWO drives on an IDE cable you must configure BOTH drives to work together.
You need to check the original drive to see what setting is currently in use.
There are three choices for most drives. Master, Slave, Cable Select (CS). Western digital drives also have a 4th type marked Master alone.
When configuring two drives you must either use CS on BOTH drives or use Master on one and Slave on the other.
When using CS, the drive connected to the end of the cable will be identified as the Master.
When using Master/ Slave settings you can connect the Master to EITHER the end OR the center connector. That allows easier routing of the cable.
If you have connected the new drive to a SECOND port on the motherboard and the drive is not showing up then the second IDE controller may need to be enabled in the BIOS.
Look at the link below for a better understanding of the jumpers.
One other thing to note. It is very important that your motherboard is capable of configuring a hard drive larger than 127GB. Watch the screens at start up to verify the BIOS is identifying all the drives by both model and the FULL capacity.
