To answer this specific question more specifically :-) you mount
formatted partitions (filesystems), not entire devices. So /dev/sdf
wasn't mounted, /dev/sdf1 was.

it isn't "bad" you are just misunderstanding what's going on.

Common usage is confusing, because we speak of "mounting a disk" or
"mounting a memory stick" which is not strictly true. What we mount are
filesystems, which in these cases are actually formatted partitions on
those devices.

Regards, K.

PS: It gets more complicated with network file systems, virtual
filesystems and the like. For many of these things there is no
"partition" involved. The general statement still holds true - we mount
filesystems, not raw devices.
