I have been using a Linux based NAS drive for storing media files and this has worked fine under Leopard and Snow Leopard. I have now upgrade to Lion and I can no longer access the folders on the NAS drive. Lion will connect to the drive but the Finder window shows folders with a red & white stop sign. Selecting one of the folders elicits a 'The folder “xxxxx” can’t be opened because you don’t have permission to see its contents.' I can see the folders and files using the terminal. I have tried connecting the external NAS using SMB and bonjour but get the same result with Finder.

 

Can anyone provide an explanation as to what has happened during the upgrade from Snow Leopard to Lion? Is there a way to reset the permissions so that I can access the files from Finder?

 

Oddly, iTunes can see the and play the files without a problem.

Mac mini, Mac OS X (10.7)

    I currently also have the above problem, (though with a newly installed snow leopard onto my iMac). All of my folders on my external hard drive show folders with a red & white stop sign. Selecting one of the folders prompts: 'The folder “xxxxx” can’t be opened because you don’t have permission to see its contents.'

     

    How did you resolve this issue - any advice would be greatfully recieved.

     

    Cheers

    After MANY frustrating hours of trying everything to regain permission to my external hard drives I found an easy and fast solution. FYI- I'm on Snow Leopard 10.6.8, though I believe this solution will work for anyone on Mac OS X 10.5 or later.

     

    1. Download BatChmod.app (http://www.lagentesoft.com/batchmod/index.html).

    2. Click on the "File" button and choose the external drive in question.

    3. Under Owner, choose "root" and check all 3 boxes (R, W and X). Under Group, choose "admin" and again check all 3 boxes. Under Everyone, again check all 3 boxes. **make sure you've checked the boxes and not just put a line in them...

    4. In Options box, check "Change ownership and privileges," check "Clear ACLs (10.5+)" and check "Unlock." Do not check "Clear xattrs."

    5. Finally, DO NOT check the box at the bottom that says "Apply to enclosed folders and files," because this is probably similar to what got you locked out of your own external hard drive in the first place!

    6. Click on the "Apply" button.

    7. Now open finder and open your external hard drive!
