I am running Windows 7 Pro (64). I have 2 hard drives installed. The (C) keeps my system and program files. A second 1GB hard drive is used for back-ups, pictures, music, etc. I checked and recked all permissions, and they are in order. There is only one user on the computer...Admin. I was able to access the drive up until a few weeks ago. I am able to scan the drive with Microsoft Security Essentials. I am able to access the drive while in safe mode...but for some reason I get this message while attempting to access it while in normal mode. Location is not available F:\ is not accessible Access Denied Any thoughts?
