Assign a Drive Letter

In order to organize your computer hard drives, sometimes changing and assigning a specific drive letter to your drives or external devices can be helpful. In a work environment where you are using network drives that have already been assigned a letter, you will want to assign a drive letter that is different from the other drives in order to avoid conflicts. If you have more than one device or drive with the same drive letter, you will only have access to one of those drives until you reassign a drive letter.

Tips

  • When assigning a drive letter to an external device such as a CD ROM or USB and it does not recognize it, check to make sure that the drive name is not already being used.
  • Make note that removable drives get automatically assigned drive letters in the order that they are connected. Once they are connected, you can still change the drive letter using the steps above.
  • In Microsoft Windows, drives A through F are usually automatically assigned by Windows, so if you want to permanently assign a drive letter to a removable drive, try choosing a letter lower in the alphabet, like X, Y or Z.

Warnings

  • Be careful when changing drive letters. If you had documents and programs installed on your drive and then reassign the drive letter, you may find that the short cuts to these programs no longer work.
