I would get the 30 day trial to satisfy your curiosity. I got version 4.51 on a giveaway awhile ago. I used it for awhile, but especially with Windows7 it seemed like eye candy. I could almost never get it to release my USB docking stations. So I ended up doing what I do now. Which is running SysInternals sync.exe to flush the disk buffers and turning off the docks. I don't have a problem.

I have HP PCs. Maybe it works better with other makes, I dunno'.
