Any reason not to use Vec::with_capacity(disks.len()) here?

I know this is an existing behavior, but would it make sense to handle the case when the slice is empty? Otherwise it could be documented that this crashes with empty slices.

Its not clear what the function does from the signature alone, imho either another type is returned or the function is documented.
