I think people care. Andre said he was working on a fix for the Seagate drives some time back. It does seem that all BIOSs leave SATA drives in PIO mode. That may be a bios bug really rather than a linux bug. But if you put the hdparm somewhere early in boot you should be ok, as a temporary workaround. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
