Cannot write to boot disk, asks authentication
Problem
Suddenly, after rebooting a Snow Leopard Mac Pro (2009), I cannot copy to the main disk, or even move one of its files, without having Mac OS X asking for authentication.
Once I type the password in the dialog box, the copy is made, but this is not acceptable nor usable in the long term. I even think most apps won't like it...
I'm talking about copying a file from the Desktop to somewhere else on the same disk, the one the system has booted on...!
History
2 x Mac Pro 2009, one has Mac OS X 10.6 Snow Leopard working properly, the second one has nothing.
I used Copy Carbon Cloner to make a clone of the first Mac on another disk then installed the copy in the second machine.
It worked for some time! Then, on this second Mac, I added another disk in bay 3 and things started to go south. I think the disk in bay 3 was faulty.
So I stopped the machine, removed the faulty disk from bay 3, and rebooted. And here the authentication problem on the main disk appeared.
What has been done
I've booted from another system partition on another disk then used Disk Utility to repair the disk and to repair permissions. No errors were detected.
I researched other answers to similar questions but they are all about using an NTFS disk, and this is not my case at all, I'm talking about a standard HFS+ Mac OS X disk that suddenly is in this "read only" mode.
Other info
If I add another disk with Yosemite installed, I can boot on it and I can copy/move/write anything on the Yosemite disk and on the Snow Leopard one.
But I absolutely need to have the Snow Leopard one also working (because of obsolete apps we still need) and rebooting again on it, the problem is still here.
TL;DR
In a 2009 Mac Pro, a cloned Snow Leopard disk asks for authentication for any file operation.
In the same Mac Pro, a Yosemite disk works properly and does not suffer from this issue, I can move files on the Yosemite disk and on the Snow Leopard disk.
Back on the Snow leopard one: the authentication problem is still here, for all disks in the machine.

Do this instead:
Open Finder, find your drive, typically named "Macintosh HD"(but in your case "MAC106"), select it, press Command (⌘) + I on your keyboard, in the window that opens, scroll to the bottom, if the text next to your username is "read and write", this isn't the solution, but if the text is "Read Only", do this:
Click the padlock, type your credentials, click the "Read Only" tag next to your username, click on "Read & Write", click on the padlock, and done.
