I have two external hard-drives in enclosures for storage. One is my “E: drive” and the other is my “F: drive.” They get their drive letters based on when they’re mounted, so occasionally, they may show up in opposite order. This annoys me when I have a program that refers to E:\ when in that case, it’s the F:\ drive. To change the drive letters of your drive, follow these steps:
Right click My Computer > Manage > Storage > Disk Management > right-click your drive > Change Drive Letter and Paths… > Change
Now you can change it to something else. Pretty simple if you ask me, but not many people know the actual place to do this.
