I just recently started playing with smartctl and discovered one of my disks seems to be having problems:<br>
<br>
Oct 5 10:52:27 mythtv smartd[13917]: Device: /dev/hdb, 4 Currently unreadable (pending) sectors<br>
Oct 5 10:52:27 mythtv smartd[13917]: Device: /dev/hdb, 4 Offline uncorrectable sectors<br>
<br>
I'm trying to figure out exactly what this means. I think as far
as the report goes, it means four sectors have bad blocks and the disk
wants to relocate them, but hasn't yet. My question is what I need to
do about it. Is it time to panic and dump the drive? It's
not a particularly old drive, but I have no idea what the warrenty on
it would be. I bought it OEM from newegg. If it's just a
matter of relocating data, what ought I do about it?<br>
<br>
badblocks gave a dismaying list, but I don't know exactly what to do
with that data. The blocks are somewhere in my LVM
partition. Is this a write off the sectors kind of problem,
or a pray and order a new disc kind of problem?<br>
<br>
smartctl reports overall health is still good.<br>
