Ivan has a 2 drive NAS that has files he needs, but the RAID 1 hard drive are reading as corrupted. He believes it is the corruption of one, synced to the other. Leo says that the hardware is probably fine, there's just corruption in the files themselves. But it could be a physical issue making it worth using SpinRite to repair it. However, if the corruption has spread, that points to a software error in the files, not the hardware itself.
