  • Dynamic disk on notebook

    I am trying to get as much speed out my notebook as possible.

    As I am having 2 internal 7200 RPM hd's, I was trying to convert to dynamic disks. Finally I would like to create a stripeset.

    MS does not support dyn disks on a notebook.

    However I tried to set HKEY_Localmahine.../IdConfigDB/DockingState to 0. Restart.
    DockingState is reset to 1 again.

    Any hints ?

    Thanks

    Are you sure that MS does not support Dynamic disks on portables?

        Doing a quick search it seems you may be able to get the functionality if you disable your AMP or ACPI (whichever you have) but this would have adverse affects on the OS controlling the hardware.

          Before you go and take the dynamic plung (I am not a fan), are these 2 hard drives master and slave on the same IDE channel?

          If so, you'll get no performance benefit. IDE writes to one drive at a time per channel. IDE isn't SCSI. Now if the drives are SATA (are laptops providing SATA capabilities?) then I imagine you won't have this issue.

          You can tell if you have both drives on the same IDE channel in that laptop as follows:

          1) In the post screen (if you can get it to be verbose and your eyes are quick) or the BIOS settings depending on what BIOS you have.

          2) Load up some system inventory software like Sandra Lite (free for non-commercial --workgroup only machines) or AIDA32 (free, old, but works on domain machines) and see what they show.

          3) Go to "My Computer\right click on Manage\System Tools\Device Manager\IDE ATA/ATAPI controllers\Primary (and then Secondary) IDE Channel\Double click\Advanced Settings". Then look at the "Current Transfer Mode" for both Device 0 (master) and Device 1 (slave) on each channel.

          You most probably the 2 drives plus the CD/DVD on IDE. The drives most probably show as "Ultra DMA Mode 5" while the CD/DVD should be as lesser value (2 - 4).

          If you have "Ultra DMA Mode 5" listed for both Device 0 and Device 1 then you have both drives on a single channel.
          Cheers,

            Thanks for your detailed reply.

            One HDs is master on the primary, the other one master on the secondary channel. The DVD drive is slave on the primary channel

            Thanks
