    A place where i am supreme emporer
    So i'm serious problems doing a Format with Zero's on my Lacie Firewire drive

    i tried using Silverlining Pro on OS 9 and the formatting option fails

    i've been thinking that maybe i could try from within Terminal, but i don't know what the command is to initialize this low-level format

    Does anyone know what it is?

    What you are trying to do is not low-level formatting. A hard disk can be low-level formatted without losing the data on the disk. It appears that you are trying a regular format. Why? What will a format do for you that simply erasing the disk won't do?

    Why are you using a Mac OS 9 utility? You should be using Disk Utility (while booted from the install CD if doing it to your startup disk) with the "Zero all data" and "Install Mac OS 9 drivers" options checked. Works for me - it's just slow. Don't try an "8-way random write format" unless you're very patient - in theory, it will take at least 8 times as long as just writing zeros to the disk, but in practice, it takes FAR longer to complete, especially with larger disks.
