And yes, this is something we need to deal with. I don't think that disks that use contact start-stop heads care so much, but disks that use load-unload heads (like most laptop drives, it seems) generally quote a much lower cycle lifetime for "emergency unloads" caused by power loss than by normal unloads done while power is still applied. It's important enough that in some cases, like the Compaq X1000-series laptop I have, the BIOS appears to have a power button handler that spins down the drive before power-down when the power button is pressed and an ACPI OS isn't running. (Holding the button down when an ACPI OS is running just forces the power off, then you get the clunk from the drive..) Windows XP (and even as far back as Windows 98) get this right, surely we can do as well :-)
Yes, windows XP could handle better the power button pressed event (causing the hd not to go to emergency parking, even when forced shut-down, most of the times). But regarding a normal shut-down cycle, isn't this a regression? You don't solve a regression adding a feature (IMHO). - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
