Hi guys, Suddenly, I'm not able to access my thumb drive in Vista. I don't know why, it popup and error message that says "Access Denied" even though I have used it before. I've tried with my other thumb drive and the result is the same none of them is working. I'm sure that I didnt set any permission for that, It must be the latest MS patches. My Account is a full Admin account with UAC turned off. BTW: All my thumb drives are still working because I've tried it on my other XP systems and they all work fine. Have a look at my screenshots: Please help, Thank you
