very strange ...
are you sure the phantom cd drive is not another cd drive ?
check all cables ... and try to remove the installed driver for the disk and update with new one.

Some burning software, e.g. some Nero suites, create a virtual CD or DVD drive, which shows up in Device Manager. It's used only for that brand's programs

See response 2 here:

If this is regarding a Hitachi LifeStudio external hard drive, see response 17 in this:

You need to tell us what the make and model of the external hard drive is.

If you DO NOT have any software that is simulating a virtual CD or DVD drive installed in Windows on your internal hard drive(s), then....

Your situation is probably similar to the one about the Hitachi LifeStudio external hard drive I referred you to.
The hard drive has a small partition on it that has software on it that results in you seeing a virtual CD or DVD drive, ONLY when the external drive is plugged in, and ONLY when the external drive enclosure's circuits are being recocognized properly and ONLY when the external drive is actually getting 500 ma from the USB port it's plugged into.
Is that virtual CD or DVD drive appearing ONLY when the external drive is plugged into the computer ??

If YES......

The rest of the drive's space has a partition on it on which you store data.
When the drive was new, you were seeing BOTH of
- a drive letter in My Computer or Windows Explorer for a virtual CD or DVD drive,
- AND another drive letter for the data space on the drive

It's very common for people to unplug an external hard drive (or a usb flash drive, or a memory card) while Windows is running WITHOUT clicking on the Safely Remove Hardware icon and choosing to STOP accessing the drive. When they have neglected to do that, sometimes, but not always, data is DAMAGED on the hard drive inside the external hard drive's enclosure.

The effects of that data damage vary.

In the case of the Hitachi LifeStudio external drive, he can see the virtual CD or DVD drive, ONLY when that external hard drive is plugged in, but he can no longer see the drive letter for the large data partition on the externl hard drive that he could see before, in Computer (in Vista or Windows 7) or in My Computer (in XP and previous, or in Windows Explorer .

If you examine the external hard drive's space in Disk Management as I described at that link about the Hitachi LifeStudio external drive I referred you to, and tell us what it says for what is on the external drive's space, we can confirm whether there's evidence data on the drive has been damaged.

In XP, to go to Dislk Management, you can either
- Click on Start - Run - type: diskmgmt.msc (click on OK or press Enter) .

- or - click on Control Panel - Classic view - Administrative Tools - Computer Management - Disk Management (on the left side of the Computer Mangement screen).

Does it STILL work well with the laptop NOW ?

If it doesn't, data IS damaged on it.

If it DOES still work with the laptop,

- does the "phantom" CD or DVD drive show up on that computer ONLY when the same external drive is plugged in ?

- the USB port you plug the external hard drive into for the PC MUST be able to supply the full max USB spec 500 ma of current.

The external drive also may NOT be recognized properly if it's plugged into a USB port that's in an external multi-port USB hub, or into a USB port on the front of the desktop case.

Troubleshooting USB device problems including for flash drives, external drives, external memory card readers.
See Response 1:

In addition to the info there....

For some desktop mboards you can have problems when an external hard drive is plugged into one of a pair of USB ports on the back of the case that are connected to the same USB controller, if there is another device plugged into the other USB port for the pair, because the pair can't actually supply 500 ma per port - they can only supply 500 ma in total. Usually those pairs of ports are one above the other, not beside each other. If you have two devices plugged into such a pair of ports, try plugging one of them in elsewhere on the back of the computer.
