Keep in mind that depending on what is wrong with the disk at the bad sectors, those sectors can spread very quickly to other parts of the disk once accessed as the read,write head sweeps over (in the case of debris on the platter). It's much better to do that as soon as possible, rather than later on in a few months after you've got your data on it and find out some of the disk is actually bad.
