The group staff is the default group every user you create on your computer belongs to. So there is nothing wrong with it.
Now, the plus sign at the end of the permissions triplet, means that there are ACLs associated to that file/folder.
As a first step, to solve your problem you can start ignoring ownership on the 2TB external hard drive
I didn't have an external disk at hand to take a picture, so I used the first one I found googleing.
This is the reference link. I hope Topher Kessler, the author of the article, that often write on this forum, could forgive my laziness
May also be necessary to remove the ACLs, but let me know if ignoring ownership is enough.
Hello and thax for responding.
No, that was one of the first things we tried.
My helpful guy in the store went into Terminal and tried to figure out why all the files were tied to Administrator and needed Root password to move or delete.
Even the folder that he created via Terminal (he added a folder just to see what happended) got the + mark after it and was there by not able to move or add files into, without admin password.
I also used the 10.6 startup DVD to go in and try to reset the ACL for my internal SSD drive, but that did not seem to help either.
There is something about these files and disk that is not giving my Macbook permissions to change the info.
Can also maybe be good to know that before the disk crashed, I managed to use time maschine to back it up. I hooked up the disk to my computer, added another backup disk and backed up my Internal MacBook drive together with the (about to) crashing disk. Then I copied the info from this time machine disk on to the New Drive.
What I believe I need is to re-write the permissions on the disk so that not only admin are allowed to change the info but I have no idea how to do that.
Hope this gives you a little more of a clue what´s is going on and that you have an idea how to solve it.
Yes, it is.
Let's start removing ACL.
Open Terminal. The volume New Music Drive must be connected to your computer.
Copy and paste the following line into Terminal and confirm
sudo chmod -R -N /Volumes/New\ Music\ Drive/
type in your password when prompted to do so and press enter. It'll take a while to complete the command, depending on how many files the disk contains.
I guess dreddfulmusic is your user. At the end the of the Terminal command, the picture you posted should have in Sharing & Permissions only 3 items
If that is so, you shouldn't have any problem manage the entire disk. If not, please report here.
