Hello from the exFAT disk! This is drive D: (/mnt/disk2), the fourth disk,
read and written by Rustbelt's own exFAT driver (src/fs/exfat.rs).

exFAT keeps long names in UTF-16 and compares them without case, so
`type "long file name with spaces.txt"` finds "Long File Name With Spaces.txt".
Try `ls -l D:/`, `cp B:/notes/todo.txt D:/` and `cat d:/MIXEDCASE.txt`.
