I only did this because I have time and patience for the time being. I truly believe that Norton Disk Doctor and Speed Disk are big screw ups! Wether they are installed on my drive or not. So what I did was completely formatted both of my MACS and reinstalled the OS again. Everything ran fine but when I ran Disk Doctor on both of them....both of them started to screw up! Both with the SAAAAAAMMMMMEEEE problems! So again I formatted and started over again. This time I ran Speed Disk. Guess what? More screw ups! Yes! On both of them and with similar problems! I even ran Speed Disk on my iPOD using the iPOD profile. Guess what happenend???? BIG SCREW UPS!! iPOD didn't want to start of shut off and there were times that it would shut off by itself! Or sometimes the volume didn't want to work. I'm not starting a arguement here. I'm just curious as to how you say it works for you but its obvious that ran the SAME tests over and over again on clean machines and NORTON keeps doing the same screw ups.
