Hi Marc,
It seems they support SCT. But is SCT enabled?
The below snippet from one of my scripts should help you determine this:
for i in a b c d e f g h i j k l m n o p q r s t u v w x y z ; do
if [ -b /dev/sd$i ]; then
echo setting SCTERC for /dev/sd$i
if smartctl -l scterc /dev/sd$i | grep -q Disabled ; then
/usr/sbin/smartctl -l scterc,70,70 /dev/sd$i
else
if ! smartctl -l scterc /dev/sd$i | grep -q seconds ; then
echo 180 >/sys/block/sd$i/device/timeout
echo WARNING /dev/sd$i does not support SCTERC!!
fi
fi
fi
done
Note that some drives claim to support, until you tell them to use it...
If you want to know why this is important, please search for SCT support
on this list. It has been discussed many times.
Other then that, the drives seem OK. I do note you are using desktop
drives in RAID, which is not recommended.
Cheers
Rudy
