In a previous article we explained how to Save Procare Data to Your USB Drive. Today we’ll tell you how to choose a drive letter (like W, X, Y, Z, etc.) for your USB drive that will always be the same. This is known as a “persistent” drive letter. The reason this matters is because drive letters can change, making them unavailable as a backup option in Procare. By choosing a letter for your USB drive you’ll know it should remain the same on that computer.
