I just setup an external drive (via FW800) for my MBP. I would like to turn off security for the drive so my two user accounts can share every file on the drive. Disk Utility information tells me the following:

Name : Data
Type : Volume

Disk Identifier : disk1s2
Mount Point : /Volumes/Data
File System : Mac OS Extended (Journaled)
Connection Bus : FireWire
Device Tree : /PCI0/PCIB@1E/FRWR@3/node@30e002e0701035/sbp-2@c000/@0:2

How can I turn owners off? I have read of others seeing an option in Disk Utility to accomplish this, but I cannot find that option (perhaps I overlooked it??).

Any suggestions?

    Select the drive in the Finder, choose Get Info from the File menu, and put a check in the box 'Ignore ownership on this volume'.

    Unfortunately, that option does not appear

    Btw - I am on OSX 10.5

    It does show a "sharing and permissions" with an add/remove button. When I press the + sign (add) it crashes the info page. The logs show the following message...

    11/11/07 10:55:42 AM com.apple.launchd[2612] (0x10a110.Locum[3747]) Exited: Terminated
    11/11/07 10:55:42 AM com.apple.launchd[2612] ([0x0-0x1bc1bc].com.apple.finder[2629]) Exited abnormally: Bus error

    I figured it out, or at least the backdoor way of doing this. The option still does not appear on the Info page, but owners are now disabled.

    The following article talks about how to ENABLE ownership. From that I figured out how to DISABLE ownership.


    vsdbutil -c /Volumes/MyDrive/
    sudo vsdbutil -d /Volumes/MyDrive/
    vsdbutil -c /Volumes/MyDrive/

    The first command displays the current status. My status read "No entry found".
    The second command disables (-d) ownership on the drive.
    The third command confirms the new status. My status now reads "Permissions are disabled".

    You just saved my life -- my iTunes library is on an external drive, and some of the permissions were borked, which prevented me from accessing files. With this, I now have access to the drive again. Thanks a lot!
