CD-ROM drive is not the D: drive

Question

CD-ROM drive is not the D: drive

Cause

Another drive or partition has been added to the computer and has made the CD-ROM drive the last drive letter.

Answer

When another peripheral is installed into the computer, the CD-ROM will automatically be defaulted as the last drive in Microsoft operating systems. For example, if your CD-ROM, DVD, or other disc drive was the D: drive and you've added a new hard drive to the computer your disc drive will now be the E: drive.
