+# We need a list of the SMART-enabled drives on the system. Choose one of these
+# three methods to provide the list. Comment out the two unused sections of code.
+
+# 1. A string constant; just key in the devices you want to report on here:
+#drives="da1 da2 da3 da4 da5 da6 da7 da8 ada0"
+
+# 2. A systcl-based technique suggested on the FreeNAS forum:
+#drives=$(for drive in $(sysctl -n kern.disks); do \
+#if [ "$(/usr/local/sbin/smartctl -i /dev/${drive} | grep "SMART support is: Enabled" | awk '{print $3}')" ]
+#then printf ${drive}" "; fi done | awk '{for (i=NF; i!=0 ; i--) print $i }')
+
+# 3. A smartctl-based function:
+get_smart_drives()
+{
