Never underestimate the possibility that you have hit a BATCH of bad
hard disks. Hard disks fail.

Now, are you doing anything to help them fail faster? What does
smartmontools say for your hard drive state? How many hard drives?
What's hdd temp? Does your system have adequate ventilation? Is all of
your recording I/O going to OS disk? Are you leaving liveTV on weeks
on end and beating up the hard drive(s) with the live tv buffer? Did
you pack your system full of hard drives, and reduce fan speed to
reduce noise?

Have you run memtest86 to verify that the issue isn't bad RAM? Failing
ram does all sorts of weird things.
