Hi,

I am making some progress:
- booted the win8.1 laptop into f22 (using a thumb-drive)
- attached the 4TB disk (as formatted+written on win8.1)
- did a checksum of the files
- all checksums correct

I now built the latest ntfs-3g (2016.2.22 from source) on the f19 machine (where I had
many failures) and am testing the disk again. 65% into the check and all the checksums
are correct. BTW there is 1.2TB of data, which is why it is being migrated from the
1.5TB disk to a 4TB one.

If it is all good then I will remount the disk using the old ntfs-3g to confirm that
it was the source of the problem.

cheers
