Interesting. The man page says:
ntfscp will copy file to an NTFS volume. destination can be
either file or directory. In case if destination is
directory specified by name then source_file is copied into this
directory, in case if destination is directory and
specified by inode number then unnamed data attribute is
created for this inode and source_file is copied into it
(WARNING: it's unusual to have unnamed data streams in the
directories, think twice before specifying directory by
inode number).
So, ntfscp needs a destination filename (ostensibly, within a directory
of the MOUNTED drive), or a directory residing within the MOUNTED drive.
So, are you 1000000% sure that you are actually copying a file from/to
the usb3 drive
WITHOUT mounting it first? Linux desktop will automount a usb drive.
I think you must be unaware that your drive get's automounted as type
fuseblk (another name for mounting ntfs drives in user space). Without
mounting, I see no way that ntfscp will copy anything
to an ntfs partition without first mounting it, or unless you have write
permissions on the block device - which would not be a wise thing to do.
From your followoup post, your drive us mounted as fuseblk.
"fuseblk" is just how an ntfs partition is reported via the "mount"
command, among others. "fuse" stands for file system in userspace.
The Linux fs type ntfs and associated utils is provided via the ntfs-3g
package.

OK.
You have to re-examine your first assertion that
