improve scanning time--- add s.m.a.r.t and drive info

The program is good. In fact a bit of a god send. I have multiple hard drives with terabytes on terabytes of all sorts of stuff. it helps me visually see the numbers. There are other free programs out there, but i prefer this one. the tree structure works, its old school. The SCAN time need improved. I do understand its limited to the speed and size of drive and number of files. I would recommend scanning in the background, compile a list of results in a special file. Then you could use that information to speed up future scans. also be able to show a detailed run down of how the user is using his or her drives. also a S.M.A.R.T should be default include. With drive info would be nice. estimated drive life expectancy.
