I will consider buying a new disk. It would be quite difficult to identify the broken bits as the filesystem resides on a logical volume built over 2 software RAID arrays (raid1, 2 disks and raid5, 4 disks). I know this is an awful mess. TV shows and movies are not so important, but I am disappointed : the RAID was inefficient to prevent this kind of problem.<br>
