hdparm for Windows (NT/2000/XP/2003/Vista, native/cygwin)

hdparm is a command line utility for the Linux operating system to set and view IDE hard disk hardware parameters. It can set parameters such as drive caches, sleep mode, power management, acoustic management, and DMA settings.

hdparm port for Windows was made possible by emulating HDIO_DRIVE_CMD ioctl function by using SCSI/IDE/ATA-passthrough APIs on Windows NT4/2000/XP.
This port isn't full featured hdparm but allows you to modify some ATA-harddisk settings that are otherwise difficult to modify under Windows.
