which showed: Enabled Supported * Host-initiated interface power management Device-initiated interface power management i.e. that HIPM and DIPM was supported, but only HIPM was enabled. That is a bit weird, since you are using this on 6.14.5 and saw lpm-pol 3, which means: ATA_LPM_MED_POWER_WITH_DIPM. So I would have expected both HIPM and DIPM to have shown enabled in that case, see: https://github.com/torvalds/linux/blob/v6.15-rc6/drivers/ata/libata-eh.c#L3510-L3521 I could not find the similar hdparm output for WDC WD5000AAKX-001CA0. Could you please post that as well? Kind regards, Niklas
