Yes, media must not be mounted during fsck check (or at last not in
read-write mode). You'll probably use system console so it's convenient
to use commands like: mount (without options shows mounted file systems)

I think  fsck.ext4 -f -p /device  would be sufficient and should repair
all common problems. If something really bad happened to your file
system, you'll be informed.
