It might be able to serve as documentation later on too. I don't think it would be wise to configure APM to certain value after matching only the drive model. That's too wide. A good solution would be... * Build database of load cycle limits and useable APM values on drive models. * Monitor load cycle count by smart commands and if it continues to increase at an excessive rate, warn the user and configure higher APM value. If you replaced the drive yourself, putting hdparm command in one of boot scripts should do it for now. :-( Thanks. -- tejun -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
