My computer won't allow me to do a scan of my disk. It keeps trying and re-trying for hours now. It says that some other program is trying to access the disk. I have shut down all the startups in the lower right hand corner of the windows screen. I have rebooted numerous times. Same result. I am running Windows 98. I have a Gateway 350MHz Pentium II computer with 256 MB Ram and a 10GB IDE Type 47 disk drive. Someone please help me out!
