I copied an AVCHD card to my backup hard drive. I renamed the folder. I am trying to backup the card but it doesn't complete the operation. i get the error message "The Finder can’t complete the operation because some data in “BDMV” can’t be read or written. (Error code -36)." I tried duplicating the folder and I got the same error message. I opened the folder in FCP X to import the files, and it takes a while to open (hello spinning wheel!) but it eventually does and I could potentially import that way. Any idea how I can backup the folder? I can't think of any fix.
