Windows: What happens if I finish drive letters? (they are 26!) [closed]
This image is not mspaint. I subst'ed all drives, even B:
Then, I plugged a card reader that has 4 drives. Nothing showed up! So, the answer to your question is NOTHING! You are just unable to add more. Of cource you can use volume mounting as suggested above
It depends on your operating system. Some older versions of windows supported up to 32 drives (mapped to things like [: and `:), but more recent versions do not.
On a modern Windows machine, if you require more than 26 drives, the correct solution is to use Volume Mount Points
