is one better to use than the other? the on e that comes on every comp to defrag, or would one that u buy on a say system mechanic be better? i have both juzt dont know what to look for or which one would be better...thanks guys
the defrag that comes with windows is decent, but if you want one with more details and options, try Diskeeper.
sorry squizzle, don't use norton, so couldn't give you my opinion. I just got Diskeeper recommended from ddp
