how to Disable write protection from pendrive

In most of the USB based flash/pen drives, write protection is provided via the small notch. First of all look for it in sides of your drive. It’s even marked with lock/unlock symbol. Move/slide the notch to unlock position (means releasing write protection) before you perform any file operations in your drive such as copy/paste/format etc. After that you can slide back the notch to lock position safely.
But many of the pen drives don’t provide hardware lock/notch for write protection. Instead they back it up by means of some software/tool. From there you can change the write protection lock/unlock option. Refer to your pen drive’s manual for more details in this regard as different pendrive have diferent ways to to unlock them or otherwise you can also take help of some tools to unlock them.

5. type< attributes disk clear readonly
(If you need help while typing commands then type “HELP FORMAT” on command prompt)
============================================================================================
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“

how to Disable write protection from pendrive

We received problem from our Reader regarding "Removing write protection from Pendrive". Here we will try to solve it.

What is write protection?

SD Card with Lock

- Write Protection is a feature(yes you read it right) 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 (hard)switch located in the Pendrive and memory card. The small yellow switch in this snap is for write protection. Similar, switch is used in any side of some pendrives.

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

First of all, make sure if there is any physical Switch is present or not, if it is then adjust it to unlock side.
If there is no physical switch or still problem persists, Go ahead.

As many a times it is done by virus also, it is suggested to scan your system including pendrive with a good updated Antivirus, if you don't have any then Download and install MalwareBytes, update it and do the scan.
For detail information of Virus cleaning, check : clean virus  

UPDATE: 

I have found a simple trick which also solves this problem (when your USB Device has minor problem only). Try this :

1) Right click 'My computer' -> Manage or Management -> Disk management
2) select your USB drive -> Right click ->"change drive letter and paths"
3) Then Rename it to a different letter

Check whether it starts working or not !!

 Note: Quotes( ' ) are used for information only, whenever you are asked to type, do without the quotes. Ex:  if asked to type 'abc'. Then don't put quotations ( ' ) while typing, type only
abc
    
 Method I : Using Diskpart


First we will try to remove read only attribute from the specific drive.

Warning : Be sure to do this on the right disk since the diskpart command can do serious damage if you run it on the wrong disk.

1)  Start Menu -> Run(or in search box) -> Type 'cmd' -> press 'Enter' -> Command Promt will open
2) Type 'Diskpart' -> enter ->  'list disk' -> enter
3) Select the disk you are going to modify, if your required USB disk is in 'disk 4' then 
4) type 'select disk 4' -> enter , now disk 4 is selected,  'list disk' will show star(*) beside it
5) 'list disk' -> enter 
To Clear the Read-Only attribute on the selected disk (To Disable write protection):
6) Type 'attributes disk clear readonly' -> enter
The disk is no longer Write protected. The Read-Only attribute is removed.

If you wish to set the write protection again, just do the same procedure and
Type 'attributes disk set readonly' -> enter

When you are done modifying the disk attributes just issue the exit command
7) Type 'exit' -> enter

If files inside USB drive are still in read only mode
-open command prompt
-Type ' j: ' -> enter (put your drive label in place of 'j' )
- Type ' attrib -r /s /d *.* ' -> enter
- exit


Method II : Using RegEdit


This will Remove write protection from USB Drives. If it doesn't then lets disable writeprotect from your System Using Registry Editor:

1) Start Menu -> Run(or in search box) -> Type 'regedit' -> press 'Enter' -> Registry Editor will open
2) Expand by clicking ' + ' and Navigate to the following path :

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies

If you can't find  'StorageDevicePolicies', then you have to create the key:
-Right click on ' control '-> New -> Key -> a new key will get created -> rename it as 'StorageDevicePolicies'
-Right click on 'StorageDevicePolicies' 
-> New -> DWORD (32-bit) Value -> Name it as 'WriteProtect'

writeProtect to storage device policies

Now if you want to enable write protection, use ' 3) ' , to Disable write protection, use ' 4) '

3)To Enable Write protect, Double click on 'WriteProtect', and set its value data to '1'

Edit DWORD value

Once set, all users on the computer is now blocked and prevented from copying, transferring or writing any files, documents and data to the USB disk drives.
4)To Disable Write protect, Double click on 'WriteProtect', and set its value data to '0'
Once reset to '0', all users on the computer is now allowed to copy, transfer or write any file, document and data to the USB disk drives.

5)close your registry edit window.

For first time, you may get that same message again, close the notification window and try to write to the USB again and it should work. You’ll probably have to do this with all your USB drives to clear that “Disk is write protected” message. Hope this helped.

If still same problem then You have to go for Formatting it.

Method III : Using Formatting

Try Formatting by Disk Management
If it doesn't format.

Try these tools:
1) Download Neo 9
(Zipped with Password - techsoln )
