We have a desktop that has a problem to start, so we are trying to copy the sata drive (connected through USB ports to our laptop to the external drive also connected through USB ports to our laptop. We are not backing up everything just copying certain data folders and are encountering a permissions issue. When copying files, it gives an error that you will need to get permission to the file. We already change the permissions at the volume levels for both the sata hard drive and the external drives to be the same, but we still experiencing the same error. Not sure maybe we are picking the correct user to assign for permissions or there's something else we should be doing.
Note: The external drive already has some of the same files we are going to copy, but we are trying just to copy into different folder and after we know the data is there, delete the old copies of the same data in the external drive.
