If you check the file system on the 160 GB external drive it is FAT32 -
hence the 4GB stone wall you're encountering. This file system is
limited to a maximum 4GB file size.

If you're going to use the external hard drive with NTFS aware operating
systems only, consider formatting it as NTFS to avoid the file size
limitation.

I don't know why the 4GB .BKF file is not working. Perhaps it is
truncated to an "incomplete" state and as such, non-functional.
