How To Change External Hard Drive and Flash Drive Letters

Sometimes it is necessary to change the drive letter of an external hard drive or flash drive. This is especially true in earlier operating systems such as Windows XP where an overlap can occur between the E: and F: drive letters if they are mapped to a network drive.

Changing a drive letter can also be a great way to organize a drive by specific categories. In many cases, people will label a “Jobs” drive the J: drive, or a “Music” drive the M: drive. This allows them to quickly remember which drive letter their drives are assigned too when doing transfers or drive selections.

Whatever the reason may be for changing your drive letter, the process is extremely easy to do in Windows 7 using the Disk Management utility. Just remember, you cannot change the drive letter of your primary system drive through the Disk Management utility, only external drives that do not contain system information.
