i tried to remove that but it is not happending. Please suggest me how to do that

Read some of the postings in this link for solutions.

you  can find step guide here

I have a SanDisk Cruzer Glide 128g and it is telling me that it is Write Protected, I did not place any write protection on the flash drive but it is there and now I cannot write anything to the drive. My first question is, how do I remove the write protect? And secondly, why is SanDisk putting drives on the market with potential problems for us consumers? Finally, the fix or repair should come from the company (SanDisk) not from us users who are experiencing the same problem. Where is SanDisk responsibility with this issue? Thanks and have a good day.


there is no fix. If it is showing write protected the drive locked it that way to prevent any possible data loss. Back up the data and contact sandisk support for a warranty replacement. if you have sensitive data on the drive let them know. they have a return process for that as well. 

Hi I did it. but it doesn’t work  (CHKDSK Command)

it says:  Windows cannot run disk checking on this volume because it is write protected.

don’t try it…wasting time

Wow. thank you so much. it works :smiley: 

well if you guys having problem with finding ‘Storage device policy’

then go to the same path :-

Navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control

then simply press Ctrl+f 

And type “StorageDevicePolicies” or “Storage Policies” any one that you like. it will take a little time 

and eventually it will  stop with highlited  text without thinking hit Delete or Press right click and choose delete and then 

try following

Step 2:

insert the USB device, then

control panel->Admin Tools->Disk Management

Your boot drive will show as C:\ and under 
Layout will be  Partition
File System will show  NTFS

How does your USB show up?

Step 3:

So if you go to  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
look for  StorageDevicePolicies  – if found, open it and look for  WriteProtect  - - delete the key

Step 4:

Try this …it definitely works…I found it after lot of research online…

i m really happy that i got my pendrive back. in working condition.:laughing:

If you cannot copy, delete or send data from your pen drive or face problem when you format it. It shows en error message like “The disk is write protected. Remove the write protection or use another disk.” 

Basically write protection allows a pen drive to keep its content from being changed.

  • Go to “start” option of your computer and open Registry editor
  • For this you write a command “regedit” on run
  • When registry editor open, navigate the location: HKEY_LOCAL_MACHINE/System/CurrentControlSet/Control/StorageDevicePolicies

I was with the same issues and I managed to fix it by converting disk from MBR to GPT layout

you can use MiniTool Partition Wizard ( ), I’ve done it using DISKPART windows utility. You can convert it back to MBR if you want.

FYI, backup everything, you will have to delete all the data from the flash drive

You do realize fabioveta that converting the disk layout requires the drive to be writable.  And since we are talking about drives that are Write Protected that means your app won’t work.  Which kinda implies your posting is basic SPAM doesn’t it?

You can try to flash your chipset by following the steps in this tutorial on How to fix a write protected USB thumb drive
