Solved DVD-RW/CD-RW not recognized by Desktop PC

Ibm / S50 8086-24u
November 14, 2013 at 05:14:10
Specs: Windows XP Professional, 256MB
I have an older model Dell Dimension 2350 desktop, which came originally equipped with a CD-R drive in the top slot and a CD-RW drive in the slot underneath. I decided to upgrade the desktop by replacing the CD-R drive with an IDE DVD-RW/CD-RW drive. The CD-R was wired as a “slave” of the CD-RW, so I set the DVD-RW/CD-RW accordingly. BTW, the cable that serves the two drives has no "twists" in the wiring.

To make a long story short, the DVD-RW/CD-RW was not recognized in either “My Computer” or “Control Panel/Hardware”. So naturally I’m wondering whether I did anything wrong. Any assistance appreciated.

I will answer my own question. After trying a series of experiments I concluded the DVD/CD drive, itself, was non-functional. I reported it to the eBay seller from who I purchased it; the seller kindly supplied me with another drive. I installed the replacement drive and, lo and behold, the BIOS immediately recognized it! No driver installs; no data cable replacement.

Conclusion: original DVD/CD shipped to me was a dud. Many thanks to everyone who responded.

Double check the jumpers on both units. There are only a few things that could be wrong.

1. Jumpers
2. power connection. Try a different power connector if available.
3. data cable issue. Cable may not be installed correctly (flipped over or turned end for end) or fully seated. The connector on the end of the cable can become damaged during removal or replacement. There are sharp pins that penetrate the insulation on the cable and can easily be displaced.

Did you remove the cable completely from the motherboard and both drives?

Othehill, Thanks for your reply. I need to amend one thing I mentioned in my original post. The Jumpers are set to Cable Select, not Slave.

Also, I know the DVD/CD drive is receiving power because I am able to open/close the DVD/CD tray.

Regarding the data cable, I did not remove it completely; I just disconnected it from the drive I was replacing and reconnected it to the new drive. One thing I need to check: whether the IDE interface connector on the new drive is oriented the same as that of the removed drive, or upside down.

The IDE cable should be keyed so it fits only one way. But if yours isn't, there's a red stripe along one edge of the cable. That edge connects to the #1 pin side of the drive connector. Also, the #1 pin side is almost always closest to the power connector.

If you jumpered the new drive the same as the drive you replaced then it should be OK. Does the drive show in cmo/bios setup?

"Does the drive show in cmo/bios setup?" No. Also, it does not show up in Control Panel/Hardware.

Just to clarify… you say the original drive arrangement was cable-select…

Is that still the situation now; "both" drives using CS (cable-select)?

What is the situation if you only connect first the previous CD-RW (it's in there alone - without the new burner); then similarly with the new burner - alone? Do you see each when they're one their own? (Test with each drive in the same position on the ribbon as the other…)

If so then I'm thinking either jumper settings (as per DaveinCaps), or the actual ribbon cable itself… It may not be correct one to use with your more recent burner…?

Some detailed info below re' cable-select (CS) - including the actual drive position on the ribbon cable which determines which drive is in effect Master and which is Slave… (depending on type of ribbon cable used). The first link mentions the two types of cable used - almost immediately… The cable you have at present may have an impact here - or not? This first site is not as detailed etc. as the second; but does cover the basics and more…

This second site is an on-line reference/bible for most anything that requires a little more understanding… The chap who hosts it deserves medal for his resourcefulness and scholarship...

I suspect it may be a cable issue; in that you may need a more modern/recent/current ribbon (80-pin over 40-pin)?

Incidentally - what happens if you set one drive as Master and the other Slave (the olde fashioned specific jumper settings approach) - i.e. you do not use the CS mode…? Although as you say your present ribbon cable has no twist in it I suspect it won't work that way…; but won't hurt to try?

Suggest you read the first link above - and then go onto the second one if needs-be…

You will note from both links that the position of the drive was important in the early days of CS - Master was in the middle of the (special) 40wire cable, and the Slave was at the end…; and it was a "slightly different" 40 wire ribbon the standard one . But with the more recent 80wire ribbon, it doesn't matter which is where… as the system sort it all out for you (or ought to…)
