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?

Plz help me I lose my data on the 8 gb flash say structure corrupted

Structure Corrupted is not the same as Write Protected.  Start your own thread.

And try running CHKDSK on the drive.

I bought a sandisk usb drive today and put some documents in it, and now it is write protected. How can I return it with my private documents?! 

See if the links posted 4 posts above your posting help.…—how-to-fix-write-protected-disks

Same here,. i’ll guess i wont return it, glad i bought two on black friday.  will wait for a solution,. 

Use GPARTED in Linux. Delete the partition table and then format it using whichever filesystem you prefer. Linux gives no craps.

After following the whole process, I have not seen StorageDevicePolicies after “Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control”  so, what should I do to format my 8 GB SanDisk Pen Drive?

Here is how to Remove The Write Protection From A USB Drive

1- Press the WIN+R keys together to launch the Run dialog box. When it opens up, type in regedit and hit the enter key.

2- As next, you need to navigate to the following path as shown in the screenshot given below:

HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Control

3- Now, under the Control key, you need to look for a key named StorageDevicePolicies.

If there is one already, you can go straight away to step 5.

Else, right click on the key Control, click on New and then on Key.

4- Name the newly created key as StorageDevicePolicies.

5- Click on the newly created StorageDevicePolicies key in the left window pane, and in the right window pane, you need to create a new 32-bit DWORD value. For that, right click anywhere on an empty space in the right window pane, click on New, and then on DWORD (32-bit) value.

6- Give the newly created DWORD value the name WriteProtect and double click on it to edit its value data. To disable the write protection from the USB drive, set the value in the Value data field to 0.
