When repairing permissions, which one do I select?

[VoodooDaddy]

Under the disc utility I have 2 versions of my hdd. Which one am I suppose to highlight to repair, or are they both the same?

Edit: I did a search after posting and found someone asked the same thing about a month ago. They were told to do the Mac HD.

Pick either one. Doesn't matter.

The first one is the physical drive, the second one is the partition on the drive. Since you probably only have one partition it really doesn't matter. If you had two installs of OS X or something you could repair one install and leave the other one be.

In short... don't matter.
