The folder "ITunes" is on a locked disk or you do not have write permission

has anyone figured out how to solve this problem? I am having the same issue, except this difference:
One user of this imac can log in and use itunes fine, but when I log in and try to launch itunes, I get that same error message (and cannot launch itunes) - "The folder "ITunes" is on a locked disk or you do not have write permission".
I am totally new to apple forums, so I am not sure how all things work, like it says at the top that:
"This question is not answered. "Helpful" answers available: 2 . "Solved" answers available: 1 ."
implying there ARE 2 'answers' available... where?

Select the icon of the HD that has the files - Get Info for that HD (+I or from the Finder File menu 'Get Info') - Look under the 'Sharing & Permissions' tab at the bottom. Check your status - to change your status then select the lock icon and enter your Admin password if prompted - then give yourself 'Read & Write'. If you are not in the list then you can add yourself by using the + button.

I am having exactly the same problem. I did what you said and i gave myself write & read privileges, but it is still giving me the same thing! any more ideas?

I had this happen to me once.

I have two users on my computer with an external HD with my itunes library. One user had itunes open, and when I was on the other "user" I could not access it.
So if you have more than one user on your computer, make sure only one user is access itunes.

Hope this makes sense and helps you out.

I just went through this problem with a newly created user (should be the same for you, being a new user yourself). I had to go into the Music folder for the user and move the iTunes folder out of the Music folder onto my desktop (this already had all of my itunes music in it). You can find that folder by double clicking the "MacIntosh HD" on your desktop, then clicking the "Music" icon on the left side of the window. If you see an iTunes folder in there move it to the trash (unless you have music in there, then move it to your desktop). That would solve the problem of the locked disk issue. Now after you open itunes and agree to the terms of use make sure that the "find music" box or similar is checked. It will automatically find your music folder on your desktop. After iTunes has completed the process of uploading the music, you can trash your original itunes folder. This is exactly how I fixed this problem for myself.
