|
|
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!
