ATA/ATAPI-7 specifies the IDLE IMMEDIATE command with unload feature.
Issuing this command should cause the drive to switch to idle mode and
unload disk heads. This feature is being used in modern laptops in
conjunction with accelerometers and appropriate software to implement
a shock protection facility. The idea is to stop all I/O operations on
the internal hard drive and park its heads on the ramp when critical
situations are anticipated. This has no effect on SSD devices!
Provides a shock protection facility in modern laptops with spinning hard
drives, by stopping all input/output operations on the internal hard drive
and parking its heads on the ramp when critical situations are anticipated.
Requires support for the ATA/ATAPI-7 IDLE IMMEDIATE command with unload
feature, which should cause the drive to switch to idle mode and unload the
disk heads, and an accelerometer device. It has no effect on SSD devices!
