What will removing the drive letter do? I can change the name of the drive via file explorer, right-clicking the drive, rename.... Im scared of doing this. Right now everything works just as before and the annoying popup warning of disk space can be turned off via notifications.
The space on the new local drive never changes either thankfully.
It is a System Partition.
My Disk 0 (C drive) has one too. Almost everyones does.
That partition was there last week, last year. It just didn't have a drive letter.
The partition needs to be there. It does not need a drive letter.
The
only reason you're getting the notifications is because File Explorer sees it as a "drive letter", and it is mostly full.
Remove the drive letter, and all is well with the world.
