+ (description
+ "Prevents shock damage to the internal spinning hard drive(s) of some
+HP and Dell laptops. When sudden movement is detected, all input/output
+operations on the drive are suspended and its heads are parked on the ramp,
+where they are less likely to cause damage to the spinning disc. Requires a
+drive that supports the ATA/ATAPI-7 IDLE IMMEDIATE command with unload
+feature, and a laptop with an accelerometer. It has no effect on SSDs.")
