SYMPTOMS

On a computer (such as a notebook computer) in which you can replace the CD-R or CD-RW drive with a DVD or CD-ROM drive, you may not be able to gain access to the files that are on the disc that is in the DVD or CD-ROM drive if you replace the CD-R or CD-RW drive with a DVD or CD-ROM drive while the computer is off and then start the computer. When this occurs, you can still gain access to the files by using a command prompt.

CAUSE

This problem occurs if you replace the CD-R or CD-RW drive with a DVD or CD-ROM drive while the computer is off and the same drive letter is assigned to the new drive.

When a writable drive such as CD-R or CD-RW drive is installed, Windows Explorer records its drive letter in the registry. If you replace the CD-R or CD-RW drive while Windows is running (this is known as "hot swapping"), the registry information is automatically updated. However, if you replace the CD-R or CD-RW drive while the computer is off, the registry information is not updated and Windows Explorer tries to treat the new drive as the writable device.

To resolve this problem, obtain the latest service pack for Windows XP. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
