lost permissions to my external hard drive

[xkappax]

Hi,
I was wondering if anyone could help me. I lost permissions to my external harddrive (named "Karl") and I cannot get it to open on any computer. When I click on it to open it, it says "The folder "Karl" could not be opened because you do not have sufficient privileges". I was just using it this morning and it just randomly stopped working.

If anyone could help me unlock these permissions, it would be greatly appreciated. I am running Leopard and am on an intel Mac G5 tower.

I typed this into terminal:
ls -alOe /Volumes
id
diskutil list
df
echo "done"

And this is the info it returned:

The 'uchg' shown next to Karl is your problem--that's the user-immutable flag. Fortunately, it's pretty easy to unset. Your permissions for Karl are also a bit restrictive (no execute permissions for anyone), so we can also change those if you'd like. I notice that your permissions on Mac_Jobs and RamVol are not at defaults, so if you have the permissions on Karl set the way you do for a reason, feel free to skip this command.

Copy/paste the following:

sudo chflags nouchg /Volumes/Karl
sudo chmod 755 /Volumes/Karl
ls -alOe /Volumes
echo "done"

This block of commands will remove 'uchg' and set the permissions on Karl to rwxr-xr-x. (user = read write execute, group = read execute, other = read execute) If you prefer to keep the execute permissions off of group and other, or ALL permissions off of group and other, you can use 744 or 700, respectively, in place of 755.

That worked, thank you so much! ^_^
