A to Z: How to Assign a USB Flash Drive Letter

By · Wednesday, June 15th, 2011

Assign flash drive letter When we plug in our USB flash drive and look under the My Computer menu, it looks a little like alphabet soup.  Random letters appear to represent each drive or removable device, but there is in fact a method to the madness.  A and B are always floppy drives and C to Z are hard disk drives, like for your USB.  What’s more is that drive letters help you to pinpoint the correct location to open, transfer or back up your files.  Different computers will also give you different letters based on their network and drives.

The importance of permanently assigning a USB flash drive letter especially comes into play to avoid the confusion and mistakes associated with system letter changes.  Additionally, your computer may not even recognize your device because its default letter may share one with the system.  As a result, USB flash drive assignment will also prove useful when plugging in peripherals such as cameras, MP3 players, portable hard drives, etc.

Here’s how you can assign a permanent letter to your USB flash drive in Windows:

–      Go to “My Computer”.

–      Click on the “Control Panel” followed by the “Administrative Tools”.

–      From there, you’ll see either “Disk Management” or “Computer Management” depending on which system version you have.

–      If your system does not give you these options, you can get to the same destination by right-clicking on “My Computer” and selecting “Manage”.

–      When it’s opened, right-click on your flash drive, which appears in the lists in the left column.

–      Choose the “Change Drive Letter” option and click “Change” again.

–      Once the list of letters appears, you have to consider your decision.  This list won’t give you the option for current letters used by other drives.  It’s advisable to steer clear of the first 10 or so letters of the alphabet, especially the letter C, which if it’s not already used for your main hard drive, is bound to be used for another in a different system.  Go for a less frequented letter of computers, which is usually in the latter part of the alphabet.

–      After you’ve made your letter choice, select “Assign the following drive letter”, click “OK” and then click “Yes”.

This process will make your flash drive letter change permanent and complete.
