(Sorry about the misspelling in the subject line. Apparently, I can't edit that.)

My rebuilt Dell Optiplex GX110 has a Samsung SN-124 compact CD drive. I decided to upgrade it with a rebuilt Sanyo SN-308 DVD RW drive.

With the DVD RW drive physically connected in place of the CD drive, I get an error message on startup. Something about a secondary hard drive not found or not available. Then I see "Press F1 to continue or F2 to enter setup utility." When I go into BIOS, the DVD shows as an unknown drive. I checked to make sure that the drive type was set to "AUTO."

I double checked all my connections, took the computer apart and put it back together, then restarted...several times. I cannot see the DVD in Windows Explorer or Device Manager. I tried adding new hardware, and was unable to locate it...just as if it were completely absent.

The drive powers up and spins. The IDE cable is the same one that the CD drive used. Since this is actually a laptop drive, there is no jumper.

I disconnected the DVD and reconnected the CD drive, and everything works fine, except that there is no DVD drive.

Is there more than the one device on the IDE cable, if so, how do you have the jumper set?

As nearly as I can tell, the IDE cable goes directly from the motherboard to the drive. In any case, there is no jumper. It's a laptop-sized drive.

The jumper that I'm referring to is on the rear of the drive. There are three settings, Master, Slave, and Cable Select.

Okay. I am accustomed to finding jumpers on full-size drives. If I remember correctly, what I am looking for is a small, rectangular object, usually insulated in white plastic, that rests on pins in the back of a drive. The jumper's orientation determines whether the drive is set up as a master, a slave, or a CS. Is that right?

The drive in question is a slimline drive, made to fit in a laptop. Dell put one of these into the Optiplex desktop PC to save space. As far as I can tell, there is nothing resembling a jumper on this drive. The drive fits into a slim metal case that snaps into the PC case before the lid goes on. On the back of this case, there are three cable connections: an IDE connection, a power connection, and a connection I am not familiar with. I do not see anything that I recognize as a jumper. Perhaps if you could post a picture, I could figure out what I need to look for.

Please note that I really do not know much about this drive. I usually work with full-size components.

I am looking for firmware on it now. Could that be the problem?

From another forum: "These laptop CD drives may not have physical jumpers. The setting of Master / Slave drive "jumper" is done electronically within the drive's firmware."

Well, I hope I haven't made matters worse. I downloaded a firmware update from driverguide, but when I tried to run it, I got the same error: Drive not found.

I think the problem IS that the old drive was configured (by firmware) as a master. This one seems to be a slave (or perhaps it's the other way around :thumbsup: ). Does anyone have a fix for me, short of cutting a cable (ala http://www.unixwiz.net/techtips/ide-cable-select.html)?

Progress: I went and got a single IDE cable, connected it to one of the motherboard connections, then put the first (middle) connector into the DVD drive and the end connector into the hard drive. When I booted, the DVD drive showed up in BIOS as "CD Rom Reader." The hard drive showed as an "Unknown Device." Huh?

I think that this means that I was right about the DVD being configured as a slave.

I FIXED IT!!!!!
(Victory Dance) :thumbsup:

Since the new drive is configured as a slave, I just removed the old IDE cable and replaced it with one that has a connector for a slave and a connector for a master. I connected the new DVD drive as a slave, and Voila! Problem solved.

All day to solve such a simple problem.
