    Cannot format write protected pen drive.


    Hello.
    I have 8GB Sandisk Cruzer pen drive.
    I used it for ready-boost my laptop for few days it was working very well then.
    I decided to stop the ready boost the when i went into properties and ready-boost tab it said "Your device is not available for readyboost" something like that. I decided to format the pendrive then error came it is write protected.
    there was a ready-boost file equivalent to the size of pendrive with no delete option. I have aomei Disk management .
    I tried to format with it no luck again. then i deleted the partition and after there i cant see my pendrive in my computer where all the drives are located.But my pendrive is getting detected .
    my Disk management show this.

    Nothing is getting detected.
    I can only see my removable drive in disk management softwares.

    If a drive or partition does not have a drive letter assigned to it, it will not show up in My Computer or explorer. Did you try diskpart?

    1.I cleared the attributes readonly and set them to readonly as mentioned in the link.
    2.I tried to clean the disk and here is what happened.

    Sounds like the drive has failed. I've used readyboost in the past with Windows 7 and no problems repurposing the thumb drive after.

    Even I used it in the past.
    When i wanted to use pendrive i went to properties to disable readyboost but it said you device is not available for readyboost.

    Just because it worked yesterday doesn't mean it will work again today? I don't have any other suggestions, you've already done everything I would have tried if it was mine. Looking at your diskpart screen shot again, it looks like you cleared the read only and then set it back to read only? Why did you do that? Just run attributes disk clear readonly.
