Mildly O/T. Hard drive power down
Is there a software way to force a drive to power down?
XP powers down drives after x amount of time (Control Panel - Power Options). I have mine set to 20 minutes. I have 1 internal hard disk where I store all my admin files (patches, software installs, drivers etc) and backup files. I only use the drive every now and again (maybe once a day), but would like to turn it off when finished. I can't be bothered spending time and money on an external casing. |

I found some options in the ATA/ATAPI specs, but I don't know exactly how you send any of the commands to the drive (manually). Hitachi has a "Feature Tool" for changing some things on a drive, but I don't see this kind of thing mentioned. It could be that the OS actually twiddles this stuff, and utilities don't bother "competing" with the OS for control. ******* You can get ATA/ATAPI specs here. Password is listed on the first link. http://www.t13.org/FTPSite/Default.aspx ftp://ftp.t13.org/docs2002/d1532v1r1a-ATA-ATAPI-7.pdf (a volume 1) ftp://ftp.t13.org/docs2002/d1532v2r1a-ATA-ATAPI-7.pdf (a volume 2) PDF page 158 of Volume 1, Table 18, has "Standby Timer" values. PDF page 29 of Volume 1, defines "Power Management feature set". - A Standby timer - CHECK POWER MODE command - IDLE command - IDLE IMMEDIATE command - SLEEP command - STANDBY command - STANDBY IMMEDIATE command The disk can be commanded to do many things. The operating system can load many of these features, when the drivers first initialize the drive. ******* Paul |
