How to change a drive letter in Windows
Today’s tip is pretty specific. Â You may never need to use it. Â I personally went a long time without needing to know how to change a drive letter in my Windows computer. Â But when the situation came up that required this to happen, it was very nice to know how to do it. Â And it’s actually not even difficult.
Can you think of a situation in which you might need to change a drive letter? Â Here’s how it came up with me, and with a few of my clients recently.
If you want to do a backup to a local drive (and you should, in addition to the automated online backup), the software that I use and recommend is called Second Copy. Â I wrote all about it here. Â When you set up Second Copy, you give it a set of instructions that basically tell it to copy your files to your external USB drive. Â When you do that, the program remembers the drive letter that your external drive uses. Â For example, it might show up as drive F. Â So the next time you run Second Copy, it looks for drive F and backs up your files, piece of cake.
BUT…you don’t leave your external drive plugged in all the time. Â When it’s not plugged in, it’s not drive F. Â And what if you plug in some other USB device, such as a flash drive, a printer, or even a different portable drive. Â When you do that, THAT drive now takes drive F because it is the next available drive letter.
That means when you plug in your external drive next time, it might now be drive G or some other letter. Â And Second Copy won’t be able to do the backup because it can’t find your drive at drive F.
At this point you have two options:
A. You can change all of the backup settings so that each one looks for drive G instead of drive F. Â That’s a fair amount of work.
B. You can change the drive letter on your external drive from G back to F. Â This is much easier.
Here’s how you change the drive letter:
1. Click Start, then right click on Computer and choose Manage. Â Bet you’ve never clicked on that before, eh?
2. Now you’ll see a new window open. Â This windows is called “Computer Management”. Â In that window, you want to click once on “Disk Management”.
3. Now look in the center column of the window, and you will see a list of your drives and their letters. Â Find the drive you want to change, and right click on it. Â Then, choose “Change Drive Letter and Paths”.
4. Now you’ll see a window pop up with the drive letter displayed, and a few options. Â Click the “Change” button:
5. In the next window, the options for “Assign the following drive letter” should already be chosen. Â Then use the drop-down menu to choose whatever drive letter you want to use. Â You can use any letter in the list.
6. After you have chosen the letter, click OK and close the remaining windows. Â All done!
You can go through this process whenever necessary. Â A warning however – you should probably never change the drive letter for your primary hard drive (usually it’s C) or any of the partitions on the drive. Â Some programs might rely on that “path” to work properly and you could mess things up if you change the letter.
