# /etc/conf.d/hdparm: Config file for hdparm # # Hdparm is a useful system utility for setting (E)IDE hard drive parameters and it can be # used to tweak hard drive performance and to spin down hard drives for power conservation # # For example, for all pata drives you can use this parameter # # all="-d1 -c1" # # If you have a Seagate disk then you may need to use -Z parameter to disable the automatic # power-saving function of certain Seagate drives to prevent them from idling/spinning-down # at inconvenient times # # hda="-d1 -c1 -Z" # # You can use -X parameter to set the IDE transfer mode for newer (E)IDE/ATA drives but you # should select the correct mode. PIO 1-4 (Programmed IO), SDMA 0-2 (Single-word DMA), # MDMA 0-2 (Multi-word DMA) and UDMA 0-5 (Ultra-DMA) # # hda="-d1 -c1 -X udma5"
