Show, which archive-part is corrupted

Sometimes archives are corrupted. Is it possible, that DO also shows the corrupted part number (like WinRAR does) and not only the corruption?

I am not sure we could do that reliably given the APIs 7z.dll/unrar.dll provide.

It's probably best left to more specialised tools (like WinRAR). I think that's OK since you shouldn't encounter corrupt archives often, unless doing something quite unusual?
