Hello everybody,
I have Fedora Core 7, with smartmontools , version 1:5.37-3.3.fc7.x86_64, smartd running like you can see:

root      2918     1  0 May13 ?        00:00:00 /usr/sbin/smartd -q never

and two  Maxtor 6L200P0 Hard Disks, but they're not in RAID mode. One is /dev/sda and another is /dev/sdb
My output for smartctl is this one:

smartctl -a /dev/sda
