on my permanent running machines since years:
/etc/rc.d/rc.local:
/sbin/hdparm -B 255 /dev/sda
/sbin/hdparm -B 255 /dev/sdb
/sbin/hdparm -B 255 /dev/sdc
/sbin/hdparm -B 255 /dev/sdd
/sbin/hdparm -S 0 /dev/sda
/sbin/hdparm -S 0 /dev/sdb
/sbin/hdparm -S 0 /dev/sdc
/sbin/hdparm -S 0 /dev/sdd

nothing more bad for disks as spinup/spindown
on modern operating systems it is unlikely that
they are not waking up very often

generally: if i get any messages like you a throw the disk away
and insert a new one, these days the price of a disk compared with
importance of relieable data is a clear decision
