Is this possibly a change in the NTFS structure that Microsoft doesn't document? Though Robert suggests the drive works under an older kernel which would suggest otherwise. I know I've experienced a corrupted USB disk that was NTFS format. Had to fire up a very stale Win7 to run the checkdisk and fix. Then I saved the data and reformatted to ext4. NTFS seems to be a continuing irritant to Linux. Cheers, JN On 16-01-07 04:38 AM, Robert P. J. Day wrote: > On Wed, 6 Jan 2016, James wrote: > >> >> >> On 2016-01-06 05:06 PM, Robert P. J.
