How Do I Remap a Drive?

By Diana Braun

The Windows operating system assigns a letter to all drives, partitions, logical drives and volumes. The letter is used to uniquely identify the drive when referenced by programs and different actions of the computer. All 26 letters of the alphabet may be used. By default, the internal hard drive is assigned “C:” with additional partitions of the drive typically assigned letters starting with “D:” and so forth. A drive may need to be remapped and assigned a new letter if the drive letters become mixed up or a specific program requires a specific drive letter.
