Solved External drive

[talsamon]

I get grey hairs with my external drive. I have changed the filesystem from ntfs to ext2, and now:
mount -t ext2fs /dev/da0s1 /media/extern

mount: /dev/da0s1: Operation not permitted

(with sudo or without)

I think this is the right command.
/media/extern (mountpoint) is owned by user:wheel

Sorry, false alarm:
First: I had already grey hairs.
Second: The external drive needs fsck.
Everything works.
