Restore Admin rights
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 !!!!!......
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.
