Change Drive letter

Windows 10

Everyone has an idea how they want their computer laid out. Some want all their hard drives have a drive letter first and then give a drive letter to their CD-ROM and other drives after that. If you have more than one hard drive. The primary drive will be drive C. However Drive D may be your CD-ROM drive. If you have a second CD-ROM drive, it may be drive E, and then your second hard drive will be drive F.

You may want your second hard drive to be drive letter D and your CD-ROM drives be drive letters E and F. Also if you have a flash drive that you disconnect and reconnect often. The drive letter can change since it is a removable device. It might be drive letter G this time but next time it will be drive letter H because you have a portable hard drive connected before the flash drive and it took drive letter G. If you use macros to transfer files to the flash drive, this could cause problems. You can change the drive letter for the flash drive to a drive letter that you know will not be used. I usually give my flash drive a letter at the end of the alphabet such as X, Y or Z.

I use hard drives that I only use for backup and I also use them over the network for other computers to back up to also. To avoid conflicts with other computers, I change their drive letters to the end of the Alphabet such as W, X, Y, or Z (depending on what drive letter is still available). This avoids a conflict.

To change the drive letter, do the following

Open Disk Management
Right-click on the drive you want to change the drive letter on under the layout section

Select Change Drive letter and Paths...

You will see the drive letter the drive is currently assigned (circled in red)

Click Change

To the right of Assign the following drive letter, you will see a drop down list (in this example, the drive is currently drive Z)

Click the drop down arrow

Select the drive letter you want to assign the drive to (the list will only show unused drive letters)
Click OK

Reboot the computer (Not always necessary but it avoids possible issues)

If the drive letter you want to move to is being used, you will need to perform the above steps to change the drive to a different drive letter, reboot and then follow the steps above to change the drive letter to that specific drive letter.

Example...

Hard drive titled My Book is drive letter Z
The CD-ROM drive is drive letter F
You want to make My Book to be letter F

You cannot make the hard drive letter F because the CD-ROM is using that drive letter. What you will have to do is perform the above steps to change the CD-ROM drive to a different drive letter, reboot the computer and then follow the above steps again. Now you will be able to make My Book be drive letter F
