Old Macmini ignores ownership on external HD's, new Macmini does not.

    Hi there - my old Mac mini has a couple of external HD's set to "ignore ownership on this volume", as they are just storing personal files, one backing up the other nightly. I transferred them to a new Macmini, only to find my backup software won't update from one external to the other (permissions type error messages), and the "ignore ownership on this volume" checkboxes on each are not checked, and greyed out.

    I've tranferred the HD's back to the old Macmini, and presto the "ignore ownership on this volume" boxes are now checked again. How can I make this behaviour transfer safely to the new comp?

    Some info:
    Old Mac Mini: 1.42GHz PowerPC G4 (10.4.9)
    New Mac Mini: 2.26GHz Intel Core 2 Duo (10.5.6)
    The external HDs are 'Mac OS Extended (Journaled)'
    Ownership & permissions of external HDs:
    Owner: me / Read & Write
    Group: me (same name, as it's given to the new mini too) / Read only
    Others: Read only

    The Group permission is at Read only, but I guess the main issue is why is the 'ignore ownership' checkbox not transferring to the new comp?
