ReadyBoost is a Windows OS feature that is used to temporarily turn a USB device, SD card or any NAND based device to a cache memory. This is mainly used to increase read-write access performance of hard disk in the system.
Using ReadyBoost is simple and can be done by configuring USB settings. However, like all other software and applications, users do encounter problems while using ReadyBoost. In this article, we explain some measures you can take when ReadyBoost is not working.
Before we start with the troubleshooting steps below, make sure you have a USB that is compatible with ReadyBoost. Once that’s confirmed, you can start with the troubleshooting steps below.
Solution 1: Make sure you have started ReadyBoost correctly
- Connect the ‘USB device’ to your PC
- Right click on the USB device and click Properties
- Select the ReadyBoost tab and select ‘Use this device’
- Click Ok to apply and save the settings
Once ReadyBoost is started properly, check if the error persists. If it does, proceed to the next troubleshooting step.
Solution 2: Clear registry values associated with your USB
Disconnect your USB drive from the system and clear registry values associated with it by following the steps below.
- Press Windows + R to open the Run window
- Type ‘regedit’ and hit Enter
- In the registry, follow the path ‘HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\Current Version\EMDMgmt’
- In the EMDMgmt folder, you will find a list of folders. Identify the folders related to your USB drive by hovering over it and delete them. MAKE SURE YOU DELETE ONLY INSTANCES OF YOUR USB DRIVE.
Once these steps are complete, restart your computer and connect your USB drive. Then enable ReadyBoost using the steps explained in Solution 1 and check if the error is resolved.
Solution 3: Format your USB drive
It is possible that your USB being used for ReadyBoost is corrupted or damaged. To solve this problem, format your USB drive using the steps below.
Note: Before you format, have a backup of all data on the drive as formatting will delete all contents on the drive.
If you find that you are unable to recover data from your USB before formatting, you may want to use recovery programs such as Remo Recover. It is a wonderful tool to recover data from corrupted or inaccessible USB’s. Refer how to recover corrupted flash drive for more details on the software or steps to recover data.
Once data is successfully recovered from the USB drive, you are safe to proceed with formatting.
- Go to ‘Windows Explorer’ and right click on your ‘USB drive’
- Click on Format and proceed with the on-screen instructions
- Then ‘enable’ ReadyBoost using the steps in Solution 1
This should help you fix the error if the issue is related to corrupted or damaged USB. However, if none of the above methods work, you can try using another USB drive. If that doesn’t work, reinstall Windows to rule out any problems with Windows. This should help resolve your issue in most cases.
