32 GB memory stick - can't take off the write protect

hi Folks
I have a 32 GB memory stick that I used with a PVR machine. Now unfortunately I can't do anythi?ng else with it. Will not let me format it or put anything on it. Have tried the DOS Diskpart and there's no switch on it to make it write protected. Any suggestions on how to solve it?

There are 4 Methoda to remove Write Protect from Flash Drives


Open Registry editor of your PC
 For this you should type command “regedit” on run.
Successively navigate to following linkHKEY_LOCAL_MACHINE\SYSTEM\Currentcontrolset\control\storatedevicepolicies( Note: if you can’t find “ storatedevicepolicies ” after “control” folder then you need to create it. For that follow instructions       mentioned below )
Open a new note pad file.
Copy this
cd\reg add “HKLM\System\CurrentControlSet\Control\StorageDevicePolicies” /t Reg_dword /v
WriteProtect /f /d 0
save it as DISABLEWP.BAT
Then copy it to start up folder.
 In right side u will be getting writeprotect option, just right click that and modify the hexadecimal value from 1 to 0
Restart your PC and enjoy!!!!

If you have transcend pen drive infected by 9u.exe which is a write protect virus then the following works like a charm:
1) Download JetFlash online recovery from:
2) Run the program
3) Specify the capacity of your drive eg.512 MB, 1 GB …..etc
4) Choose “repair and erase all data” OR ” repair and keep existing data”
5) Progress bar starts…….completes
6) Notification appears —” format complete”
7) Unplug and plug your drive and …..presto


Method #3

1. Start > Run  -> type “CMD” and press enter
2. type< diskpart
3. type< list volume
4. type< select volume # (# is the number of the USB HDD you’ve pluged in)
5. type< attributes disk clear readonly


There are a series of options in the Group Policy Object Editor that deal with read/write permissions on hard drives and removable media.  I basically changed their individual settings from “Not configured” to “Disabled”.

Start -> Run… -> gpedit.msc -> OK
Computer Configuration -> Administrative Templates -> System -> Removable Storage Access

In here I disabled all of the “Deny read access/write access” options; you may only want to disable the ones relating directly to the type of media that you want to access.

Here are the ones I changed:

Removable Disks:  Deny execute access
Removable Disks:  Deny read access
Removable Disks:  Deny write access

Double-click each one and select the ‘Disabled‘ radio button.

Do the same as above, except the first step is “User Configuration” instead of “Computer Configuration“

what is the error message when you try to format it via windows?

it could be that there are still routines on it which windows is trying to access or at least makes the OS think that it is still in use and therefore cannot be formatted at that time.

did you try a live-cd (bart-pe, g-parted, ..) and tried to format it from there?

what brand is it? if it is a sandisk, maybe you've got u3 on it ; here the removal tool;

@wshty - there is a file: MM_Play_time and a folder called PVRRECORD on it. Any time I try to remove this file or folder from the memory stick I get the following message: the disk is write-protected. I actually wouldn't mind this so much but when I try to put anything else on the disk I get the same message " The disk is write-protected. Remove the write protection or try another disk".
I had used it as the removeable disk with a PVR system and that seemed to have done the job...
