[mythtv-users] Any way to tell which tuner card might be bad?

I rebooted and forced and fsck. Looked like it came back clean. 

# df -h

I also show this in the log on reboot. I grepped messages for smart:

I also grepped for "error" and did not find anything about the drive.

I'll try to check top while some recordings are going to see if the wa
percentage goes up.
