[mythtv-users] Disk Report, Is this Still Safe to use? (Was: Muti-Year Installation Major Disk Corruption)

[Douglas Wagner]

Update: smartctl has returned no issues for the disk from either the short

with as many corrupted files as I was finding, this thing should be
spitting out errors at me all over the place...
