There's no reason it should (that I can think of, at the least) and I've never seen it happen. When you run an import operation, it's essentially just the controller looking at the selected disk and confirming that it can read it's data. If it can, the disk is brought into the array. If not, the import would fail and leave you essentially where you are now.
