Use Any USB Drive With Windows Vista Readyboost

By on April 25, 2007 in For Your PC | Comments { 4 }

ReadyBoost is a disk caching system introduced in Windows Vista that relies on flash memory to boost system performance. At the moment only certain flash drives are compatible with Readyboost, but gHacks have found a way so that any USB drive can be used with ReadyBoost.

  1. Right-click the device that you want to use for Readyboost and select properties.
  2. Switch to the Readyboost tab and uncheck “Stop retesting this device when I plug it in”. Then unplug the device from the computer before you proceed.
  3. Open Regedit and go to the key HKLM (Local Machine) -> SOFTWARE -> Microsoft -> Windows NT -> CurrentVersion -> EMDgmt which displays a list of all known USB devices on your computer. Choose the one that you want to use for Readyboost and edit the following keys in the right pane:
  • Device Status – Change that value to 2
  • ReadSpeedKbs – Change the value to 1000
  • WriteSpeedKbs – Change the value to 1000 as well

After that is done you can use the USB device for Readyboost.
