Second hard drive - can be seen, but not used?

Well, first of all you shouldn't launch dolphin with sudo, rather use "kdesudo". this prevents root taking ownership of configuration files in your home directory. Only use sudo for non-gui commands and use kdesudo for GUI apps. I don't know if this is the cause of your problem or not, could be.

I tried it (kdesudo dolphin) - regular permissions are still grayed out.

Another, cleaner way to do this is to install the rootactions-servicemenu http://kde-apps.org/content/show.php?content=48411 which gives you root access via the right-click dialog.

I added samrog131's repository but I don't know how to install anything from it.

"Regular" permissions are grayed out, starting Dolphin with sudo. Doesn't seem like they should be, does it?

Did you first remove your acl changes (remove your user and the mask entry in the advanced permissions dialog), the "regular permissions" should work again after that?

It seems rog did some clean up on his ppa (and the menu was never in the ppa for oneiric, probably because the menu is now installable with GHNS)...you can grab a slightly outdated package for natty here:
https://launchpad.net/~samrog131/+ar...y~ppa1_all.deb
(This package should work fine on oneiric as well, the later changes to the menu are mostly GHNS fixes). The latest version of the menu is available with GHNS or manual installation. Of course you don't need the menu to make the changes, it's more of a convenience tool.

That did the trick.

Got another problem. The terabyte hard drive is running sloooooow. It's taking 20+ minutes to move 1.5 gigs from the SSD to the terabyte HD. It's impossible to save anything to the terabyte HD from GIMP. It'd take forever if it didn't crash GIMP hard.

Rootactions-servicemenu is now successfully installed.

You should really start a new thread with this issue.
