Windows 2000, XP and 2003 Server will allow you to move or modify drive letters on hard drives, CD-ROMs or other devices that make use of a drive letter.

The main thing to remember that modifying a drive letter can contain undesirable effects. E.g. if you have a second hard drive using drive letter E and have programs installed on it. If you modify it to G then when you tick icon to open that program, Windows will look for it on E drive and it won’t be able to open it. It is suggested that you only modify drive letters on drives that store data and not programs.

Obviously you do not want to modify C drive or Windows drive to the other letter or else you are not going to have a running PC any longer and Windows won’t allow you do it anyhow.

To modify or include a drive letter to a drive you just right tick on My Computer and choose Computer Management. From there you can double click Disk Management. You will get listing of all drives in system.

From here you will see information about your drives:

What type of disks you have

Whether they are basic or dynamic disks

How big they are

What file system they are using (FAT32, NTFS etc.)

To modify a drive letter right tick on drive you would like to modify and select Change Drive Letters and Paths. You will obtain a dialog box with choices to add, change or remove drive letters.

Remember that you can only utilize letters that are not in use. If you want to utilize a letter allocated to that drive you want to modify letter on other drive first to release letter you want to utilize. After you choose letter, tick on Ok and you are finished.
