First we need a probe to see how much space is at the specified data directory, and then we can handle that

I'd go for the design on the left, where the reason is stated directly in the item.

Something to consider is whether that option should even be selectable in the first place. If the user lands on this page, and the default is disabled, we should just not auto-select any option.
