Can't gain write access to secondary hard drive root-level folder I have a second hard drive installed on my Mac. On its several root-level folders there's only one I can't get write access to.

I've tried right-clicking it, select "Get Info", unlock it, click the plus sign, select my name, change my name, &amp; everyone to "Read only to "Read &amp; Write", click the gear icon, "Make Me the owner" &amp; "Apply to enclosed items." 

Even after repeating those steps I still can't rename or delete this folder. How can I gain write access to it?
Do you need permissions to exist on this volume?  If not use the "Ignore permissions on this volume" checkbox, and that will take care of all of the problems.

Also - I would run disk utility's verify to see if there are any problems with it.
