Folder placement information

Hi

I am in the process of troubleshooting a missing drive, and the pool is showing I have unduplicated files on it. When I look at the file placement in the Balancing options, I can see the missing disk as a "?" on the right with the rest of the disks, but when checking the folder locations, apparently there is nothing allocated to that disk. I there a way of telling what folders the pool has placed on that disk so I have an idea what is potentially lost?
