    Canada EH!!!
    Did you change the disk permissions?

    -Click on the HD icon on the desktop (single click to select it).
    -Click on File at the top of the desktop.
    -Then click on Get Info
    -At the bottom of the window that opens you should see Sharing and Permissions
    -This should show you the permission settings for system, admin, etc.
    -It should be set to Read & Write
    -If it is not, you can click on the lock icon at the bottom of the wondiw tat opened and enter your admin username and password.
    -Then make the necessary permission changes.

    Hope this helps.

    When I verify Disk Permissions,

    I get this:

    Also, if i change the 'everyone' to be able to read and write, then my permissions are custom access.

    Changing external disc permissions

    Excuse me but...i'm having almost the same problem.
    My external HDD's (coming from windows pc) aren't show any settings (admin, etc) in the 'Sharing & Permissions' field...
    I have 4 Lacie HDD's and only one of them is 'read & write', all others are for read only but...i didn't changed anything. So, any help how to change the remain 3 into 'read & write' ??

    Loss of Admin Privileges?

    This could be a loss of Administration Privileges, can you save stuff, ie a new 'Pages' document or photographs?

    I can't see this menu in the specific field in any of my external HDD's, except the installed Mac HDD only. So, i can write & save etc in ony one of them (speaking of external HDD's) who is by itself adjusted for write & save etc...All others are only for read, buut the strange thing that before maybe a month i could do everything in all HDD's !!!!!......

    Restore Admin rights

    Sorry to be late getting back to you, I have had a couple of hectic days.

    Your initial post only mentioned your internal HD, so what follows applies to that drive.

    If you can't save anything to the internal HD the odds are that you have lost Admin Privileges, why; I don't know, but at the moment the 'why' is not important, you need to get them back in order to have a fully functioning computer, follow these steps to get your admin privileges sorted out.

    1. Boot from the Leopard DVD whilst holding down 'c'

    2. If 'English' is selected in the first dialogue box, click OK. if it is not
    selected, select it then click OK.

    3. In the next box select the drive and the Admin user account.

    4. Delete the password (even though it may be correct) and then enter a
    new password (or re-enter the old one).

    5. Click on 'Reset home folder permissions', then 'Startup disc', select the
    drive you want to restart with and then click on 'Restart'.

    6. When this is done go to your 'Applications' folder and select 'Utilities',
    'Keychain', then look for 'Update Keychain' and click on it.
    This should restore all your admin rights. it's not hard to do, it sounds
    more difficult than it really is, take your time and follow each step
    carefully, good luck.
