This _is_ the generic way, if your drive doesn't support it you are out of luck. > Are the commands different per HDD model / manufacturer? > Then we might need some information to send the proper > commands to the different types?!

Just make sure to choose a suitable laptop drive, then. -- Jens Axboe
