    Want to Disable Old CD Drive, Can't Remove It


    Hello, my computer is rather old. Running Windows 8.1 though. However, I have an old LG CD-RW drive in my tower, as well as a DVD-RW. The CD drive makes noises when there are CDs in it, but the problem comes in is the fact... drives are set as old IDE. And the HDD is a Sata 3GB/s HDD (It's only 500GB).

    Complicating things is the fact the cable is daisy chained between the DVD and CD drives... Basically I dunno if I can remove the CD Drive without disabling the DVD in the process. Also I don't have the cover plate for that slot.

    How would I disable the old CD drive? And further more, would it have an effect on my boot speeds?

    All you need is to disconnect the flat ribbon cable and the power connected to the CD drive and no, it would not have any effect on boot speed.

    For reals? That's all?
    Huh, it's just since its a really old standard that I keep thinking that the top drive will NEED the power from the CD Drive.

    He told you right. Just try it, not like anything will blow up.

    If you don't also disconnect the data cable the bootup process [BIOS] will look for it. If you don't plug in a replacement you might get an error in the boot sequence unless you also disable that drive in the BIOS. Windows reads the BIOS to determine what resources it has to work with. On older computers the data cable is usually about 1.5" to 2" wide with 3 plugs, one for the motherboard, the other end for the Master drive and the middle one for the Slave drive. I'd make sure the working drive is on the end plug.

    Are we talking 486 days here? Don't think he'd be running 8.1 on it.

    The 40-pin, or 80-conductor, data cable for PATA drives was common on 386 computers and up until just a few years ago and one or maybe two sockets for it may be present on modern day computers even though there will be 2 to 4, 6, or 8 SATA ports on the motherboard. The only late-model computers I haven't seen those sockets on have been the SFF/Small Form Factor machines.

    I remember when our process engineering department got its first 486 "workstation". It was a 486-25 with 4 mb of memory and a 120 mb hard disk. The company I worked for (that started in a small garage) made and sold the computer. It was a tower system. The year was 1991 and the list price was $ 15,000. I think it ran Windows 3.0 or 3.1.

    Most of our desktop computers were 386-16 computers with 1 or 2 mb of memory and 40 mb hard disks. How far we have come.

    I admit, I haven't seen the old stuff for awhile. I tend to move on quickly. You obviously know more about the generational steps. Just surprised to see it still being used. You need to take over now.

    Each device is getting its own power from a 4-pin molex type connector (Yellow=12V, Red=5V, the other 2 are ground). On second thought, you only need to disconnect the power from the CD. If there's no power feeding to the CD then BIOS won't even see it.

    @Berton
    FYI, MASTER/SLAVE relationship is physically setup via a jumper on the IDE type CD/DVD/HD. It has nothing to do with whether you connect to the first or second connector, it is a straight thru cable after all.
