PK y�!\ZP9�C C README.acousticnu �[��� Automatic Acoustic Management ============================= Most modern harddisk drives have the ability to speed down the head movements to reduce their noise output. The possible values are between 0 and 254. 128 is the most quiet (and therefore slowest) setting and 254 the fastest (and loudest). Some drives have only two levels (quiet / fast), while others may have different levels realized between 128 and 254. To be able to use this with hdparm, you will need a current kernel with the -ac patches applied. Maybe the kernel of your favorite distribution will already include this (SuSE has it in their current kernel, for example). Just try to compile hdparm, type "hdparm" and have a look for "-M" in the output. If it doesn't appear, your kernel most likely doesn't support it. You can get the acoustic setting by typing hdparm -M /dev/hda To set the most quiet mode use hdparm -M 128 /dev/hda For the fastest setting use hdparm -M 254 /dev/hda Now test different values and try to hear the difference. :-) Not all disk drives support this setting - and the speed impacts may also vary between different manufacturers and models. If you see lines like kernel: hdb: task_no_data_intr: status=0x51 { DriveReady SeekComplete Error } kernel: hdb: task_no_data_intr: error=0x04 { DriveStatusError } in your syslog, then your harddisk will most likely not support Acoustic Management. Perhaps you also wanna have a look on the IBM Feature Tool, available at http://www.storage.ibm.com/hdd/support/download.htm. I would welcome any feedback to <gernot@hillier.de> Gernot PK y�!\�o=� � TODOnu �[��� Mark's TO-DO list for hdparm: ============================ - Find a new maintainer. - Add "wipe-drive" functionality via SCT WRITE_SAME (or manual). -

fixed "help" line for "-v" hdparm-2.1: - fixed formatting of DMA info line - added "(DANGEROUS)" to -u,-X,-W options in "hdparm -h" - changed order in which settings are applied: placed standby last hdparm-2.0: - added this file to the distribution - added -f and -q flags to hdparm.c and hdparm.8 - added -N to gcc in makefile - changed installation paths to /usr/local/* in makefile - removed meaningless CPU% measures - removed -s and -x flags - added new -AKPSWXZ flags using new HDIO_DRIVE_CMD ioctl - removed BLKFLSBUF ioctl from everywhere except -t (there may be a kernel bug in the implementation of BLKFLSBUF when used on an active (mounted rw) filesystem). -
