Drive Setup 1.6.2: Hard Disk Drivers Not Updated from 1.6.1

I have noticed that after updating my hard disk drivers with Drive Setup 1.6.2, the version numbers do not change from Drive Setup 1.6.1 in the Get Info window of my hard disk.

- Why does this happen?
The changes in Drive Setup 1.6.2 were only to the Drive Setup application. The hard disk drivers installed by Drive Setup 1.6.2 are identical to the drivers installed by Drive Setup 1.6.1.
