I'm in a right pickle - unhiding a volume

I wanted to test hiding an external volume and used the following command in Terminal;

chflags hidden /Volumes/volumename

I then tried to undide it using;

chflags unhidden /Volumes/volumename

The volume did not reappear in my finder window.

I then tried;

sudo SetFile -a V /Volumes/"Drive Name"

and I was then prompted for a password.

For a while, I was repeatedly entering the external drive password and it was never accepted.

I then found out that the password is my computer username password, but also, that I had to register that in Terminal first. I did that but I am still unable to unhide my external drive.

Can anyone suggest what I can do?

OK, I found the solution.

The command to unhide is not unhidden - it is nohidden.

Got my volume back!

So, is this drive encrypted?

Did you restart Finder & Dock after the changes?

From my notes...

Open Terminal & paste this in, spaces are important...

chown root /Volumes/

chmod 1777 /Volumes/

then right after the last / of each line, carefully type the name of that external volume, & if it has spaces in it enclose the name in quote marks.

See this User Tip by Niel: I accidentally set a disk's permissions to No Access ...

If the disk in question is your Mac OS X startup disk and your computer stops starting up at the blue screen, restart with the Command and S keys held down, and enter the following commands:

mount -uw /

chown root /

chmod 1775 /

exit
