Use any USB Disk for Readyboost

by Karthik on August 15, 2007 · 3 comments

Windows Vista, has a wonderful feature called ReadyBoost. You can use flash memory devices, such as universal serial bus (USB) flash drives, to improve performance of Vista without having to add additional memory (RAM). The flash memory device serves as an additional memory cache i.e. memory that the OS can access more quickly than it accesses data on the hard disk, simply because USB drives are a tad faster than Hard Disks.

However, not all USB flash drives are supported to use ReadyBoost. In order for USB drive to be recognized, you can use the following registry hack.

Please Edit the registry at your own risk. It can screw up your PC and make you eat chickens!. As always, backup, backup, backup! dailyApps is not responsible for anything that happens to your PC if you try this!

Here are the steps that you need to follow to make this hack work. Backup all data before you proceed.

  • Let Vista test it and if it says the device cannot be used, theb check the Do not Retest this device checkbox.
  • Unplug your USB Device
  • Go to run dialog box and type regedit and press enter
  • Navigate to the following key HKLM > SOFTWARE > Microsoft > Windows NT > CurrentVersion > EMDMgmt.
  • Find the key related to your USB device (the device vendor and name is present in the key)
  • Change the following codes for the key that you selected in the previous step.
    Device Status 0��02
    ReadSpeedKBs 0��1000
    WriteSpeedKBs 0��1000
  • Thats it, close the window and plug in your USB device and yeah Readyboost works for your Windows Vista Installation.

Hope this tutorial helped you. Please drop in a comment to tell me how it works.. I don’t have Vista on my Machine but it works on my friends PC fine.
