Very disappointed with your defrag product ! I have a ThinkPad T510 with a 500GB disk, which is about 1/3 full.. It takes anywhere from 1 to 1 1/2 hours to defrag the disk, even if I Defrag daily ! Another bad point is it deletes all my Restore Points everytime it runs. I have checked my disk with ChkDsk, and the utility from the disk manufaturer, it reports nothing wrong with the disk. Is this the best product you can put out ? I am normally a very happy customer of Symantec products, but not this one.
