I have the following problem.
First, I thought I had problem with power supply, so I changed the power supply. This is not the problem. When I boot my computer I sometimes see my SAMSUNG CD/DVD-ROM (2-3 years old) is not detected (black/ empty secondary slave position). I have not set any jumpers as these should be no need for that. But sometimes it is detected and working completely NORMAL. In windows, 50% of the cases my CD-ROM works COMPLETELY FINE, but after 5-10 minutes I get the message that my CD-ROM is unplugged and it completely disappears from windows. But when I press the eject button to test it the CD-ROM ejects nicely. It seems the CD-ROM somehow disconnected from windows (2000).
I thought I had bad power supply, but this does not seem the problem.

Re: CD/DVD ROM disappears
I would think either your IDE cable is faulty or the IDE connector on the motherboard, try swapping cables or use a double IDE cable on IDE 1 connector.
You may have a faulty drive ide connection input in which case a new DVD Rom is the answer, only cheap nowadays.

Secure that the power supply of your DVD/CD-ROM is connected. Then, if it still doesn't read, buy a new DVD/CD-ROM. Most of the times, it's just the power supply that is not properly connected to your ROM.
Locate where your CD or DVDROM drive connects to the motherboard and make a note of this. Make sure you know exactly how the gray cable was connected.
Have the new DVDROM drive handy and unplug and/or slide out (depending on setup) the old one. Unplug the cables from the appropriate places. You do not have to unplug the one going to the DVDROM. Wiggle back and forth gently and then pull out.
Attach your new cables and reattach to motherboard and power supply where you removed the old ones.
Reattach the power cord and cables, but do not close up the computer entirely yet.
Test your new DVD player by placing a disc in the drive and ensuring the green light comes on and you hear it power on. If this happens without a problem, then close up the case. If not, then check to make sure cables are securely fastened in the correct motherboard slots and to the power supply
To solve this follow these instructions: NOTE: After removing these registry keys and rebooting, it may be necessary to reinstall any CD or DVD recording application
1) Close all open programs
2) Click on Start, Run, and type REGEDIT and press Enter
3) Click on the plus signs (+) next to the following folders
4) This folder is the DVD/CD-ROM Drive Class Description in the
registry. Look for any of the following names in the right hand column.
5) If any of the above keys shown in step 4 are listed, right-click on them and choose Delete 6) After deleting the keys, close the Registry Editor
7)uninstall the drivers for cd drive and dvd drive from device manager and then
7) Reboot your computer 8) Open My
Computer and check to see if your CD or DVD drives have returned. You
may also want to open Device Manager and verify that there is no yellow
exclamation on the CD or DVD drive
try scanning the system there when it finds the cd rom it will prompt for installation of drivers than give the path of cd driver ,but very rarely it happens ,so kindly check the power cable of drive if it doesn't work change the powercable
Try changing the power socket attached to your DVD drive with other available one, and restart your machine. If it is not yet shown in My Computer. try replacing the ribbon connector from motherboard to DVD Drive. If it is not yet shown in My Computer you try then to enter setup from start up to manually detect your DVD Drive. If you need to buy a new drive you can get it at any computer shop or at dell service center.
You will need to connect to cables.1 is from the power supply and one is from motherboard.Just connect both to the ROM and start the computer.Windows will automatically install the drivers for your ROM..
Check if you have both cables attached to the CD/DVD drive. There are usually 2 that needs to be connected: the SATA or IDE (that ribbon-like connector that goes right to the motherboard), and the power supply (a connector that has 4 colored lines going to the power box). Make sure they are snug, and if necessary, try changing them with others that are known to work (there should be lots of spares). If the CD/DVD light blinks or powers on upon boot, it means power line is OK, but data cable connection is bad.
According to the Toshiba website, the scsi cd-rom/dvd-rom does not require a driver to operate, but the driver for the scsi controller card it plugs into may need to be reinstalled or updated. Visit the following link, and go to the section labeled scsi cdrom/dvdrom. At the bottom of this section there are two links to websites where you may be able to find the drivers for your scsi controller card.
