Dimension 4600 can't recognize CD/DVD drives

Jump to solution

My 4600 running Windows XP (and now dual botting with Ubuntu) can't read my two CD drives. One is the original drive. What I did was put in a hard drive from an older dell and it runs OK. At one time it did recognize the drive, after I did a regedit. But then I swapped that drive out for a DVD burner, which wouldn't work. Swapped back and the original wouldn't work. Now I have both in there. The jumpers are right, the ribbon cables are connected tight. Both have power, but the computer BIOS won't recognize them and neither will Windows. I removed anything that might conflict, like Nero and Power DVD. I'm stumped. Anybody?

The tech at CompUSA needs some remedial training -- I had a Gigabyte H67 microATX with Core i3 CPU installed in a Dimension 3000 chassis. (The B110/1100/2400/3000/4600/4700 all share the same chassis and front panel wiring.) And, to finish it, I modified the front audio connector to fit a standard 2x5 header. To top it off, I had the 2tb hard drive set up for a Windows 7/OSX 10.6 Snow Leopard/Ubuntu triple boot. (Yes, I had what was probably the world's only Dell Dimension 3000 Hackintosh.)

The main concern is that the cables are short and may not reach the headers on some boards. The Gigabyte 1155 board (with UEFI BIOS and solid capacitors) I used didn't have that problem.

To what position are the jumpers on the optical drives set to?

Both are set as CS, which is what all the material I have read recommends for most products but especially Dell.

Cable Select is the correct position.  Did you try each drive alone with that drive connected to the end connector of the IDE cable?  The fact that nothing shows in the BIOS could indicate one of the drives is bad or the IDE cable may be a problem.

I amsure both work and have tried both drives individually at the end connection. I even updated to the latest BIOS. The setup does says no CD installed and does not give me an option to boot to one. I'm also thinking cable at this point and I'm getting ready to go to Radio Shack, which is nearby. Not sure they will even carry old gear like that. I can get it online for 50 cents but probably $5 to ship. Thanks for the response.

I agree with trying the cable since the drives do not show in the BIOS.  Let us know your progress.

Well, the $5 cable from Radio Shack didn't help. According to Device Manager PCI Simple Communications Controller is missing a driver and doesn't work. I think that has something to do with the drives, but I don't know where to get a driver. I have an external CD and could install it if I had one. I'm getting a headache.

I don't know how that affects CD drives.  Do a search for 'PCI Simple Communications Controller'.  You will find a number of downloads for this.

I don't think it is the PCI driver. And I can find XP drivers for CD drives. But how can I install a driver if the Device Manager can't even see the drive? I don't think it is a driver problem. I'm darned if I know what it could be. I can't fathom how a motherboard and BIOS can "lose" a device it used before. I don't care that much about Windows because I may wipe it anyway but It is a problem if Ubuntu can't find and use the drives. (On the other hand I probably could buy an IDE burner cheap and put it in but if it doesn't recognize that either, then what/) What really perturbs me is that Dell makes their cases so that you can't replace the mother board. What's up with that, anyway?

The 4600 motherboard is micro-ATX, although the chassis front audio port connector is of the Soundblaster type. (The port itself is standard Intel HD.)
