23 longDescription = ''
24 Provides a shock protection facility in modern laptops with spinning hard
25 drives, by stopping all input/output operations on the internal hard drive
26 and parking its heads on the ramp when critical situations are anticipated.
27 Requires support for the ATA/ATAPI-7 IDLE IMMEDIATE command with unload
28 feature, which should cause the drive to switch to idle mode and unload the
29 disk heads, and an accelerometer device. It has no effect on SSD devices!
