Hmm well its just i have the Norton utilities as a HFS disk image, and currently no burner and to Defrag the HD u need to boot of the Norton disk.

Would it be possiblt to boot of the MacOS reinstall cd, mount the disk image, run Norton and defrag the HD? Or would that not work cause its not *really* a disk?

Well seeing how the disk image would still be read off the hard drive you want to defrag it probably won't work...but then again if you can make a RAM disk to store it on that should work.

And I'm kinda confused as to why you are asking this...just try it and see if it gives you the error message saying Noton needs to be on another disk or not. And if worst come to worst you could actually buy the Norton software, god forbid!

yes it's possible, but you need to put the little 'speed disk' app on an other partition (or ram disk)
you don't need to boot from the norton CD, you just need to boot from another partition...

Yeah thats what i thought. Buy a program, heavens no, thats what Carracho is for Besides once i get my burner (By my count in a few weeks) i can just burn it from there, i don't need to defrag THAT bad the damage is just moderate. O well thanks for your help guys.

What kind of computer do you have?
Is it your iMac that you're talking about?
If so booting from the RAM disk is not an option...

Create a RAM Disk. Boot from CD. Use Disk First Aid to erase the RAM Disk (it won't show up when booted from CD otherwise) and copy Norton files to RAM disk.

The custom routines in NUM SD 6 for wiping free space or a minimal optimization are fast, quick, and move most of the files - 80% so that you get most of the benefit and don't need to take 2 hrs.

Of course having scratch drive or volume you can keep each optimized more easily, and if you stay 60% or less utilization little need. If you really need free space, a scratch volume would probably make more sense (audio, video or CD burning).

Yes that'd be fine
What he means is make a RAM disk but don't boot off it - merely copy the app to the RAM disk and run it form there, not the hard drive. Like a temporary hard drive partition...
