    Default Windows Vista ReadyBoost Problem

    Windows Vista has a lot of nice new features that make working with the computer easier and more fun. Apart from the graphical changes there are quite a few technical improvements. One of those improvements is ReadyBoost.

    This feature enables high speed data transfers over the USB bus. ReadyBoost is basically a disk caching mechanism, which is intended to boost system performance. But it will also speed up your USB device.

    Unfortunately ReadyBoost will not work for all USB devices. If you have a problem with ReadyBoost in Vista, it is most likely a compatibility problem with your USB device. Devices that add extra USB ports can also be a problem. In some cases it can be fixed by a driver, but this will not always work.

    So what if nothing works? Well you can still try to get the device to work using some registry tweaks. Follow these steps:

    1. First, remove the USB device from the computer.
    2. From the Windows Start menu, select Run. In the Run box, type regedit and click OK.
    3. In the Registry Editor, locate the following key:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EMDMgmt
    4. Open the key and select the name of the USB device that causes problems.
    5. In the right-had panel select the entry with the name: DeviceStatus. Right-click the entry, and select Modify from the popup menu. Type a value of 2 and click OK
    6. Next, right-click the entry with the name: ReadSpeedKBs. Again select Modify in the popup menu. Now type a value of 1000 and click OK.
    7. Repeat the previous step for the entry with the name: WriteSpeeKBs. Again use a value of 1000.
    8. Close the Registry Editor. Select Exit from the File menu.
    9. Lastly, connect the USB device again.

    This windows vista tweak will force Vista to use the ReadyBoost feature on your USB device, even if the USB device did not pass the required tests.

    Dont you think using such methods only 'fools' Vista into thinking that such USB drive are compatible?

    Can we then really expect any performance gains in such cases?

    This is one of hacking things ... it's not recommended, but if we don't have money for the purchase of new usb readyboost perhaps someone will find it as useful thing ...

    Can you use any USB for Readyboost ? Or are these being made by a few companies only. Because I have one, which said ReadyBoost compatible or something, tried it and saw no difference.

    No, you can't use just any key drive for ReadyBoost. It must meet the performance requirements which have been predetermined in the Windows registry.

    Check here to see if you have a compatible device:
    ReadyBoost Compatibility Chart

    If you have a device fast enough to work with ReadyBoost then I recommend using it. You may not notice a difference but there is a difference.

    The tweak posted on this page simply tricks Windows into accepting devices that are not fast enough for ReadyBoost requirements. Following this advice will cause extremely sluggish performance.

    It is valuable in a sense that now everyone is aware of a performance reducing tweak if they didn't know about it already.
