Comment 2 for bug 1429470

Thanks for taking your time to report this issue and help making Ubuntu better.

From what I can find, the string in question seems to be this one [1], which also originally states "The partition tables of the following devices are changed:". Though from the context this appears in, I would guess this is the list of changes which will take place _if_ the user proceeds.

(Marking confirmed based on your screenshot)
