Hello,
I am having an issue with Norton Ghost 10, I also downloaded the trial verison of Norton Ghost 14 and the same issue occurs. If I boot my computer up with 500GB usb drive attached the computer will blue screen. If I analyze the dump file it says the cause of the blue screen is symsnap.sys. The blue screen error code is 0x0000008E. If I unplug the drive the computer will boot fine and I can plug the drive in and use it with no issues after the computer is fully booted up. I have two other smaller usb drives that can remain plugged in it all times, even through boot up and will not cause any issues. Does anyone have any ideas why this may be happening? I have confirmed Norton Ghost is the problem because if it is uninstalled and I can boot the computer with the 500GB drive attached.
