Thanks. I've tried mounting it in an external reader and get the same problems so I guess it must be the disk. Nearly all the contents were backed up so I've not lost too much. Time to buy a new HDD....
Is there any reason I can't put an off-the-shelf 5TB 2.5" SATA disk in the box? I'm hoping that if I just buy the disk, put it in the box, and Initialise it, then that should work. Am I wrong?
Thanks,
Dan
