That is a tempting option. It sounds like that software works very well for ext2/3/4. The easiest thing for me would be to just give him the NTFS volume and the Paragon NTFS software ($20 for NTFS, but $40 for ext) and he should be good to go. That has the advantage that it also works with Windows, making it easy for him to copy files from a computer in his workplace, if that situation ever comes up. Mike
