Trick to unlock your Write-protected 

pendrive or SD card:

 This a very common problem while using USB flash drives or SD card. Sometimes when you try to copy or delete files you get an error message "Remove the write-protection or use another disk". Furthermore, it won't allow you to format it! 

Now we will see what this write protection is:

Write Protection is a feature that is generally found in flash drives like pen drives and memory card. It prohibits users to write anything to the drive, thus protect the drive from any modification to its data and also stops virus (from computer) to Copy (write) itself to the drive.
Initially, it was done using a small physical (hardware) switch located in the Pendrive and memory card.

Now, this feature is also being achieved digitally without any Hardware.

Why is it a problem then?
-it is a Problem when:
a) We don't know about it and it prohibits us from writing.
b) It is (digitally) implemented without user consent either by someone or by Virus.

Solution:
Make sure whether there is any physical Switch is present or not, if it is there then adjust it to unlock side.
If there is no physical switch or still problem persists, go ahead with given methods.

Method 1:
1. Start > Run -> type “CMD” and run as administrator
2. Type< diskpart
3. Type< list volume
4. Type< select volume $ ($ is the number of the USB HDD you’ve plugged in)
5. Type< attributes disk clear readonly

Method 2:
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:
www.transcendusa.com/Support/DLCenter/Software/OnLineRecovery.exe
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. Open Registry editor of your PC
2. For this you should type command “regedit” on run.
3. Successively navigate to following link
4. HKEY_LOCAL_MACHINE\SYSTEM\Currentcontrolset\control\storatedevicepolicies ( Note: if you can’t find” storagedevicepolicies ” after “control” folder then you need to create it.
5. For that follow instructions as 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.
6. In right side u will be getting WriteProtect option, just right click that and modify the hexadecimal value from 1 to 0
7. Restart your PC and enjoy!!!!

Method 4:
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“

* If u try method 3 and 4 together, you will get best result.

Method 5: Using Formatting:

Try Formatting by Disk Management if it doesn't format.
In disk management, you may need to “Partition the drive“. Don’t worry, partitioning a pen drive means allocating it its File System and Cluster Size.

Try these tools:

1) Download Neo 9

2) Transcend's Online Recovery Tool

3) Apacer Formatting Utility

4) Using Killdisk

http://software.lsoft.net/KillDiskSuiteFree-Setup.exe (setup)

5) Using registry

Using 1st two is simple.

For using Apacer Formatting Utility,
Unzip this utility to preferably in a folder on desktop for easy access (Don’t save it on pen drive).
Keep your pen drive plugged in

Double click on the 'Start.bat' file in the folder where you unzipped the above utility.

This will start formatting your pen drive, wait till the formatting completes and the LED on your pen drive stops blinking.

Remove your pen drive and plug it in again.

If you still face same problem, go to service center. If you have warranty left then replace your pendrive.

All the methods are tested and found working on my PC.

Thank you…!!!
