My Book Duo 20Tb RAID Won't Backup

I have had a My Book Duo 20Tb for the past year or so and it has worked without problems.

I have just bought a new PC and transferred everything over.

I have tried setting the backup several times, Either I click Backup Now and nothing happens or, if I reboot the PC it will start the backup but stop around 5% of the way through (40.86Gb of 680.97Gb).

Before setting it up again I deleted everything from the drive using the WD utilities.

Does anyone have any idea what might be wrong?

Thanks in advance,

Martin
