Airdisk Backup to Disk Image
 

I am using SuperDuper to create a sparse disk image (read/write) on an external drive and then plugging in my Airdisk USB drive locally to my Mac and backing the files on the airdisk using SuperDuper to the disk image on another USB drive. It works, but some of the folders within the image report that I don't have the correct permissions to open them and other folders on the image open fine. Any ideas how to fix this, as I am not sure all the folders have all the data since I can't open them.

Try turning ownership off for the USB drive (it's in Get Info for the drive).
