Installing a second CD-Rom drive

[Guest]

I curently have installed in my first bay a dvd-rom/cd-rw drive and am attempting to place a cd-rom drive in my second bay. I am using one ide cable becuase it is the only one available and no space is apparant for a second. this cable supports two devices however, my computer only will recognize one or the other. How do I get it to recognize both?

Check on the back of the drives. There should be a series of pins (6-8
of them depending on the drive). There should also be a little plastic
jumper connecting two of the pins. The first drive, your DVD Combo drive
should be set to Master (you may have to read the drive or manual to
figure out what setting is Master) and set the second drive to Slave.

Clarification - the drive on the end of the cable is Master and the drive on
the middle connector is Slave.

Only when the jumpers are in the "cable select" position.

I have connected IDE drives in some instances using the middle
controller for the motherboard connection, master drive on one end and
slave drive on the other. Works just fine.

Wrong. If the jumper is set to master the device MUST be on the end of the
cable, same with slave - jumper to slave - middle of cable. I've been
building systems for years.

"Assuming cable select is not being used, any connector on a standard
40-conductor cable can go to any device, because all 40 wires are
connected "straight through" to all three connectors. Since two of the
connectors are closer to each other than the third, the distant
connector is normally attached to the motherboard (or hard disk
controller card). The other two devices can be used for either the
master or the slave, and it doesn't matter which is which. If a single
device is used, it should be attached to the connector at the end of
the cable, and the connector in the middle of the cable left
unattached. Using the middle connector and leaving the end connector
unattached is technically allowed for regular PIO and DMA transfer
modes, but leaves part of the cable "dangling". This is called a stub
and creates much worse electrical characteristics on the cable, due to
reflections from the unterminated ends of the cable wires. It is not
recommended."
