    I'm just doing an initialization (zero all data) on my iMac running Mac OS 9.2 (Disk Utilities application). It's taking a fair while. On Mac OS X you use Erase and Install which just takes a few seconds. Is the Mac OS X erase and install as effective? Does it do exactly the same job. Any thoughts?

    "Erase and Install" erases the data, and like you said, it's pretty quick. I doubt it goes as far as zeroing the drive, since the drive is immediately going to be written to, destroying the erased data anyway.

    If there are any HD experts out there, please correct me if I'm wrong.

    What application would do a zero all data on Mac OS X! I have not heard of any?

    Here's a one:

    I can't seem to find any data on whether or not Norton does.

    Thanks, I have seen it around but never really looked at it before.

    Drive Utils

    You can boot off the OS X CD and go in to disk utilities... you can Zero out your drive there... it will talke a very long time (if your drive is big). Norton Speed Disk (part of Norton Utilities) will do it, Disk Warrior, and TechToolPro. I think Drive 10 will do it too.. but I have never done it my self with Drive 10.
