Windows 10: USB turned useless after used for Readyboost

Hi I used my usb flash drive for ReadyBoost, but now the flash drive became useless. The windows promotes to format but give message 'The disk is write protected'. I checked the flash drive's property the drive is completely full. I tried to remove write protection using commend 'attributes disk clear readonly'; however, the problem still persists.

:)

 

Got VISTA? Want to use READYBOOST with a regular USB KEY?

well, I dont know if this was covered here before or not. But after seeing the new OCZ readyboost available FLASH DRIVE, I decided to see if you can just us a regular USB key. Turns out you can.... Now I didnt write this up, just found it using google. Just figured I would pass it on.



ReadyBoost requirements for USB keys are as follows:


The USB Key must be at least USB 2.0.
The device must be able to do 3.5 MB/s for 4 KB random reads uniformly across the entire device and 2.5 MB/s for 512 KB random writes uniformly across the device.
The USB Key has to have at least 64mb of free space.

If your USB key is at least USB 2.0, but is rated slower for the random reads and writes required to use ReadyBoost, more than likely you have seen this message:





If so, plug in the USB Key, and cancel Autoplay if it pops up.

Click on Start button, and select COMPUTER. After Windows Explorer opens, in the right window pane find the USB Key you want to use.

Right click and select Properties, then select the ReadyBoost tab and uncheck Stop retesting this device when I plug it in.



Click OK and safely unmount the USB Key from your Computer.

Before Proceeding - the next step includes exporting the registry key to use as a backup if needed. DO NOT SKIP THIS STEP. As a safe guard, you may want to create a System Restore point when making configuration changes to your System.

Open the Registry (click on the Start button and type Regedit in the Run field).

Navigate to:
HKLM (Local Machine) \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ EMDgmt.
Right click on EMDgmt and select Export to back up the Key to a location on your Computer (you may also want to copy to a CD or USB drive that can be accessed if needed).





Under EMDMgmt will list all the USB devices that have been connected to your Computer. Select the USB Key you want to use with ReadyBoost and click once on it (in this example I have selected the FIRELITE USB drive).

In the right window pane, modify the following values:

- Double click on Device Status and change the Value Data to 2 then click OK.
- Double click on ReadSpeedKBs and change the Value Data to 1000 then click OK. (after clicking OK, the value may be displayed as Decimal - 4096)
- double click on WriteSpeedKBs and change the Value Data to 1000 then click OK. (after clicking OK, the value may be displayed as Decimal - 4096)





Close the Registry when completed.

Plug your USB Key back in to your Computer, cancel Autoplay if it pops up, and go to Start \ COMPUTER and find the USB Key. Right click and select Properties, then select the ReadyBoost tab and you should now be able to use it with ReadyBoost.





Keep in mind, ReadyBoost benefit is to only enhance performance for random access reads and is used as a read-ahead cache program.

Enabling USB Keys that is rated slower than the specification required by ReadyBoost may not give you the performance boost you are looking for. Also if your PC is Dual Core and has 2Gigs or more RAM, you may not notice any performance boost when using ReadyBoost.

As always test first. Your mileage will vary.

Readyboost

Hi,

Thank you for posting your query in Microsoft Community.

I will assist you with this.

ReadyBoost can speed up your computer by using storage space on most USB flash drives and flash memory cards.

ReadyBoost uses the Superfetch service that should be enabled and set to "Running" and "Automatic".

For ReadyBoost to effectively speed up your computer, the flash drive or memory card should have at least 1 gigabyte (GB) of available space. If your drive or card doesn't have enough available space for ReadyBoost , you'll see a message telling you to free
some space on it. For best results, use a flash drive or flash memory card with at least double the amount of available space as the amount of memory (RAM) in your computer.

I would suggest you to try the following steps and check if it helps.

1. Plug the flash drive into a USB port on your computer.

2. In the AutoPlay dialog box, choose Speed Up My System.

3. The flash drive’s Properties dialog box appears with the
ReadyBoost tab upfront.

4. Click on ReadyBoost tab.

5. Choose the Use This Device option.

6. Click OK.
