+# /etc/conf.d/hdparm: config file for /etc/init.d/hdparm
+
+#
+# Note that options such as -y which force *immediate* power saving options
+# should generally not be placed here.  The hdparm init.d script may run at
+# anytime with respect to other init.d scripts that do system wide drive
+# scans (like the hald script), so they will merely get spun right back up.
+# If you wish to use these options, please use the local.start init.d script
+# instead so that you're guaranteed that it will run last.
+#
+
+# You can either set hdparm arguments for each drive using hdX_args,
+# discX_args, cdromX_args and genericX_args, e.g.
+#
+# hda_args="-d1 -X66"
+# disc1_args="-d1"
+# cdrom0_args="-d1"
+
+# or you can set options for all PATA drives
+pata_all_args="-d1"
+
+# or you can set options for all SATA drives
+sata_all_args=""
+
+# or, you can set hdparm options for all drives

+# ------
+# if /dev/ide exists, find all block devices beneath it named disc, cd, or
+# generic.
+#
+# for the disc and cd ones, if there is a a matching /dev/hdX symlink and
+# hdX_args is set in the config file, use hdX_args.  otherwise, if there is a
+# matching /dev/discs/discX or /dev/cdroms/cdromX symlink, and discX_args or
+# cdromX_args is set in the config file, use discX_args / cdromX_args.  finally,
+# if all_args is set in the config file, use that.
+#
+# for the generic ones, sort them and look for genericX_args in the config file
+# or use all_args.
+#
+# if /dev/ide does not exist, check the /dev/hdX entries, and see which ones
+# correspond to real devices by opening them for reading.  then check hdX_args
+# and all_args in the config file.
+#
+# for each device considered, if no args are found in the config file, do not
+# run hdparm.
