The current drive, a new drive, was installed at that time (late June). It's as if smartctl is at least in part simply re-displaying results from the last run I did on the old drive last June. Also, the output is basically the same whether the smartctl parameter is "sda", "sda3", or "sd?". The "Disks" I was referring to is what Samuel identified. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
