Well, something is wrong if you cannot set the drive for maximum performance.
If you had the maximum performance setting at one time and now you don't, something has happened--presumably because you used Hard Disk Sentinel.
There is no evidence at the Samsung site that your drive supports AAM--yet you tried to change performance/acoustic settings.
With a third party tool, no less.
Not a good idea.
As I said, I have no idea if you can get your max performance setting back. I know nothing about Hard Disk Sentinel.
