First time ever that I encountered Linux and Unix today when I was in a computer store, trying to get help with my external harddrive.


I have a MacBook Pro 17" with a SSD 256 drive. I recently switched from my initial 128 GB SSD drive to this bigger drive. Only used Carbone Copy Cloner and that was no problem. The only thing was when I started the new disk I asked for the "User permision folder" (or something like that). Otherwise it works fine.


I also have a 2TB hard drive that have crashed. But before it crashed I used Disk Warrior on it an managed to back up everything on a new 2TB WD hard drive.


Seems like I managed to get all the info from it, but after copying it, something has changed with the permits to read and write.
The disk is open to all users (set under the "Get Info" folder)


I went into the store and a really friendly guy helped me with doing some stuff in Terminal and he discovered that there was a + sign behind RVX ending on the folder and files.
He said that this means that only the Root Admin can change this and this is the reason I have to enter Password everytime I try to change any of the files.


The "Group" that this drive has is called "Staff" but I dont have a user on my computer called "Staff".


I now need help to either add the group to my computer so that the disk recognizes the Macbook Pro as a "friend" or need instructions how I can re-write the disk so that it´s opens up to be used by all computers (or at least mine)



Best Regards
