Uau, that's a large disk. Or busy. Usually, it's about two hours or so.

Mine crawls while doing the surface test part. On my older disks I can 
continue working almost transparently.

Not the system log, but the smart log that resides in the disk; you can 
dig it out with "smartctl -a device".

Right. If I interpret it correctly, your sda has four sectors remapped. It 
probably can work like this for years without problems, but watch it, and 
if they keep increasing, you should think oabout replacing the HD.

Disks are designed so they survive bad sectors, it's a normal ocurrence, 
and they are prepared for that. But if they keep growing, then it becomes 
a problem or a symptom of failure.

Yep, I noticed, because you sent also a CC to me: in those cases Pine 
shows a yellow mark :-)
