Changed HD permissions - No Access!

[Englika]

I have 5 partitions on 3 harddisks. While installing Snow Leopard on one of them I Lost access to ALL of them. By using the Installer DVD I managed to fix the Snow Leopard one but the rest are locked.
I can't change permissions even as an admin, tried Terminal, nothing works, I'm getting desperate (and tired-It's 2:20 in Sweden now).
The symbol of the HD in the info shows a HD with a padlock on it!
Is there a Terminal command to unlock it? I have never used Terminal until this happend.
If I don't reply at once I'm probably in bed but I hope somebody has helped me when I wake up.

Thanks in advance

look up the chown command. You'll need to use sudo in front of it, but that should do the trick

The syntax is chown -R <user>:group file so you'd need to give a wild card and let it do its thing. Be sure you're in the directory you need to be, because -R will make it recursive.

I highly recommend you type man chown in the terminal to see the details of the command.
