Accessing SD Card by modifying Registry
This way of disabling write protection is simple but if Registry is mishandled, your operating system will be disrupted. So we’d recommend making a backup copy of your Windows Registry before you take action following these steps.

~########################################################################################################################~
1. Open Registry editor as an administrator (Start – regedit).

Running Regedit as an Administrator

2. Navigate to the catalogue HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\. If it doesn’t have a folder named StorageDevicePolicies – create it. For this:

2.1. Right-click on the current catalogue Control
2.2. In the menu select New – Key; name it StorageDevicePolicies.
3. Right-click on the StorageDevicePolicies and select a new value of the parameter DWORD(32-bit) for a 32-bit OS or QWORD(64-bit) for a 64-bit one respectively.

4. Rename DWORD/QWORD to WriteProtect and double-click the line changing value to 0 (HEX).

Disable protection using diskpart utility
Diskpart is a console utility in Windows 2000-XP and higher which enables you to manage disk partitions and volumes at a low level of access.

When we connect to an SD Card via console and format it we remove 'read only' protection and unlock memory card. Here is how to remove write protection on micro sd card by this way:

Open the command prompt (cmd.exe). Type "diskpart" to start the utility.
Type "list disk" to show the list of available disks in the system.
Find your USB flash drive on the list; type "SELECT DISK n" where n stands for your memory card with the write protected partition.
Type "clean" (you may have to repeat it two or three times).
Type "create partition primary" to create a new partition on the memory card.
Type "select partition" to select the partition on the disk.
Type "active" to activate the disk.
Type "format fs=ntfs" to format to NTFS (make sure you selected the right memory device!).

diskmgmt.msc utility
This method of disabling write protection is suitable both for SD Cards and USB sticks. We are going to use an alternative utility diskmgmt.msc.

Start menu – Run – diskmgmt.msc, Enter
Navigate to the context menu of the partition that needs formatting
Click “Delete volume” and confirm your choice
In the context menu click “New volume”
Choose primary partition
Leave default parameters

Disable write protection using GPEdit
It can happen that access to an SD Card is restricted by Windows local group policy. To remove the 'read only' restriction take the following steps:

Start – Run – gpedit.msc.
Go to Computer Configuration – Administrative Template – System – Removable Storage Access.
Disable parameter "Removable disks: Deny All Access".

More ways of removing write protection (if the others failed)
Scan your SD Card for viruses. Malware applications set up their own control over your files and won’t let you overwrite them. Use any effective antivirus.
If your SD Card has a write protect switch, toggle it to enable access.
Upgrade your SD Card firmware. The exact model can be found in Google by chip vendor and chip vendor model, the data available in the Device Manager.

You can remove write protection from the memory card via Registry, as well as using diskpart and diskmgmt.msc utilities (in Windows). As an option, format your SD Card to FAT32 using the tools mentioned at the top of this guide.

I have Samsung S3600 which can’t write files to the memory card anymore. The funny thing is that there is a couple of files left on the card: two photos and a video, and there’s no way I can delete them. I did delete them from my computer but somehow they are back on the memory card. I can’t transfer any files to this memory card either. I never dropped my phone on the ground or into the water, the card just stopped working all of a sudden. How to disable write protection?
I bought a microSD SanDisk 128GB for my Samsung Galaxy A5 (2016). When I insert it into my phone, it works for a short while and then prevents any files from being written on it. I’ve tried loads of things: formatted it on my PC and phone, but no use, it only helps for some period of time and then access is restricted again. Why is my sd card write protected?

[Answer]
The file system on your memory card can be damaged, so you can’t write any new data onto it. In such cases we recommend scanning disk for errors using a basic tool chkdsk. Should it fail to help, format your SD Card using SD Formatter.

I’ve no idea what happened to my memory card: when I connect it to my computer, it says that I must format the Drive J before using it. When I try formatting it, I get a message that disk is write protected.

It prevents me from removing volume by the right-click using diskmgmt.msc, other operations can’t be performed either. The SD Card file system is Raw, and the system writes that it works. I wonder what to do, how to remove write protection and restore my memory card?

[Answer]

If the disk prevents any files from being written to it, try opening your SD card in a different operating system.

Besides Disk Management, you can use any disk manager such as Partition Magic or Acronis Disk Director.

1) Sandisk Ultra USB 3.0 16GB. I’ve done everything, from changing the letter to clearing the Registry. As soon as I start formatting, a message pops out that Windows can’t do it, and the USB can’t be found. I also tried HDD Low Level Format Tool v4.40 Final – same thing. How to perform formatting of a write protected USB stick?

2) I can’t format my microSD. It writes: Windows was unable to complete the format. I used a bunch of tools and the command prompt but can’t even delete files. I click “delete”, take out microSD and insert it back. The file that has just been deleted is there again. Neither deletion nor format works.

Answer. Use other format tools: SDFormatter or soft provided by the developer on their web page (sometimes using them you can format a USB stick or microSD bypassing system errors).

The problem can be also in Windows or configuration of the computer. Format your memory card on another computer or in a different OS (Windows/Mac OS/Linux).
