Errors when moving files between different hard drives.

When I try to move files from the Linux ext4 partition to the "fuseblk" partition, I always receive two errors:
- Access denied to {destination}. Retry or cancel
- The file or folder {source} does not exist. Retry or cancel
Finally, to move the files well, I have to copy / paste / delete, with the consequent loss of time.
Is this error normal, and is there any way to avoid it?
