Because there's nothing special about drives in Linux. They're all just
files/directories. /media has no special meaning to the kernel, only the
user, so the system will happily let you create folders wherever you want.
If the folder happens to be physically located on another drive, it will put
the files there. That's one of the beauties of Unix-like filesystems - it
all looks the same regardless of drives/partitions/etc.

It's up to you to check that the drive is there before running rsync.
