  • HELP! One of my Hard drives went “read only” on me!

    Posted by Anthony Popolo on July 28, 2009 at 6:33 am

    Hi,
    I just upgraded to os 10.5, and when I was done, one of my hard drives (not the startup drive) became “read only”. I can access all the files on it, but I can’t resave any of them or any new files to that drive!
    I did a “get info” on the drive and the permissions are all greyed out with the words “Read only”.
    How can I change it to “read and write”???
    Thanks.
    Anthony

    Do “Get Info” (CMD-I) on the drive, see if “Ignore permissionas on this drive” is checked.

    Hi,
    At the bottom of the “get info” panel, the “Ignore ownership on this volume” is NOT checked. However, it is also grey-ed out so I can’t access that checkbox.
    Also, just above that shows a list of names / privileges as follows…

    “System”/ read and write
    “admin” / read and write
    “everyone” / read only

    I’m assuming I fall under “everyone” (since I’m ” read-only”)even though I’m the only user (and admin).

    How do I change that privilege?
    Thanks
    Anthony

    Hi Chuck,
    thanks for your input.
    I still have an OS on the other drive (so I can run a couple of classic programs I still use). I had to startup on that drive (as the admin) and changed the permission for “everyone” to read and write. So when I came back to the new OS, I was able to read AND write ot it.
    Thanks for getting me thinking!

    Glad you found a work around. Be sure to repair permissions after any update or when these issues pop up. Since you were/are the admin that should not have been an issue. But I have found that non-system drive permissions can be problematic with OS X, though each update has improved on this.
