#!/bin/bash if [ ! -x /usr/sbin/hdparm ] ; then echo "Missing hdparm" exit 1 fi for disk in /dev/sd?; do echo "$disk: `hdparm -I $disk | grep "Serial Number:" | awk '{ print $3 }'`" done |
Another wrapper (like mdstat), that’ll look through my Western Digital disks and fix any disk not having the head parking timeout set to a configured value.

Well, I needed a way to watch the mdstat progress (because a disk just failed …).
