Re: your post (#7)
Interesting quote and no doubt an interesting article but if you have a lot of data on a drive and you never defrag it, as wanderer said, it can, and likely will, eventually stop your system from working properly.
Considering the fact that running defrag takes no real effort on the part of the user, I have to wonder why a person wouldn't run it once every month or so!?!?
With regard to the topic at hand.....
I've used Norton defrag since back when my computer was a 486 running DOS. I've stuck with it because it used to be the best defragger out there. In fact, the defrag utility in Windows 9x/ME actually was made by Norton. But unlike the Norton defrag, MS never updated it so it never improved it stayed static and the Norton defrag was much faster by the time 98 came out.
Nowadays, I don't bother installing it anymore. The defrag utility in XP works just fine. Obviously, the more data you have on a drive, the longer it'll take to defrag but as a rule of thumb, and out of long standing habit, I start a defrag before I go to bed so that it's done in the morning.
I remember when it took 6 hours to defrag a 212 MB hard drive with 200 MB's of data on it...............lol
The only thing I'm annoyed about is I can no longer move the swapfile to the front of the drive. It used to be you could with Norton but the last version of Norton System Works I bought just wouldn't do it even when I told it to. XP's defrag doesn't even have that as an option.
