I ran one of the performance reports today, which claims I have a disk with the dirty bit set. Recommended running chkdsk..... Fired up a command prompt and typed chkdsk v: /f/r/x And got: Access Denied as you do not have sufficient privileges. You have to invoke this utility running in elevated mode. SO, I right-clicked and ran the command prompt as an Administrator. EVEN THOUGH I'M ALREADY AN ADMINISTRATOR. Got exactly the same result. Went into the command properties and SET the thing to "Run as Administrator". Same result. UAC is turned OFF. There are days with Windows 7 where I feel like everything is 2 steps forward and 1 step back. How do I make it let me do a simple chkdsk - no I DON'T want to set something to have it run at boot, or go find some 3rd party program to do the same thing. I just want to run chkdsk from this box from a command windows. How do I do this?
