Of course there is always a better option. Launching programs that access the hard drive, such as indexing or defragmenting the drive, helps for a while. Forcing the drive to be busy delays ticking. There are multiple causes for that, including power management and shock detection.The clicking sound occurs only when the drive is idle. The click sound is usually caused by the drive parking its head. Many users have reported a problem with hard drive clicking, sometimes described as a repeating tick tick tick type of ticking sound, or a faint beep at random intervals. HDD APM and hard disk drive clicking sounds In other words saving energy is achieved by decreasing performance and to a certain extent shortens drive life. Aggressive power saving settings allow the hard disk drive to stop its spindle motor and park heads more frequently, which allows saving as much energy as possible, but put stress on mechanics and leads to delays on drive reads caused by waiting the magnetic disks to spin up to the necessary speed.

Power consumption is reduced by adjusting spin speeds and disabling internal components when not in use.

Additional explanatory information is output when the '-long' option is used (and still more if the '-long' option is used twice).The Advanced Power Management feature (APM) present in virtually all modern hard disk drives is aimed to save energy and power consumption by regulating the performance of the hard disk drive. This utility's internal tables can be searched and output with the '-enumerate' option. Rather than try and document all of these here (or in the man page), another approach is taken. This utility currently contains over 500 entries spread across generic mode pages, transport specific mode pages, vendor specific mode pages, Vital Product Data (VPD) pages and their fields. Apart from SCSI disks, such devices include CD/DVD drives (irrespective of transport), SCSI and ATAPI tape drives and SCSI enclosures.Ī small set of commands associated with starting and stopping the media, loading and unloading removable media and some other housekeeping functions can also be sent with this utility. More generally sdparm can be used to access parameters on any device that uses a SCSI command set. When the SCSI device is a disk, sdparm's role is similar to its namesake: the Linux hdparm utility which is primarily designed for ATA disks that had device names starting with 'hd'. The sdparm utility accesses SCSI device parameters. Sdparm works as a command line application an it is used for getting and setting SCSI mode page fields.
