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..= =2E=20 If you want to know why this is important, please search for SCT suppor= t=20 on this list. It has been discussed many times. Other then that, the drives seem OK. I do note you are using desktop=20 drives in RAID, which is not recommended.
