Hi Manpreet gill,

You may need to disable write protection. In order to do so, run the Command Prompt as an Administrator and type the following commands:
List disk
Select disk n (n must be the number of the drive)
Attributes disk clear readonly

Now write protection should be disabled and you should be able to format the drive. If the drive keeps showing wrong capacity, test it on another PC.

Hope this helps

Step 1: easy PROCESS: sd Formatter

1 - download and install this code (from the sd card Organization) :

2 - Open the program, and choose the proper drive (in my case is G:), after that simply click "FORMAT"

3 - you have got simply formatted your sd card!

step 2 - DiskPart

Don't worry. you can remove write protected for your SD Card using DiskPart, Regedit command, or the SD card format software, like FAT32 Formatter,EaseUS Partition Master, AOMEI Partition Assistant, etc.
Input “diskpart” in the Windows search box, press enter.
Type “list disk”.
Type “select disk n”, where n is the number of write protected SanDisk USB flash drive, microSD, SSD, etc.
Type “attributes disk clear readonly”.
Input “regedit” in Windows search box, and then press enter.
Locate the following path in Registry Editor:
If the StorageDevicePolicies doesn’t exist, create it manually.
Then double click “WriteProtect” and set the value from 1 to 0, then press OK.
After you removing the write protection, format the SD Card with Partition Assisntant to restore SD Card to full capacity in Windows computer.

Alternative Solution

1. Download Partition Expert Free Edition for Windows 10, 32-bit or 64-bit install package or portable package to Run;
2. Right-click on SD card and select Format Volume to proceed; (external disks are always listed under internal drives and disk names are displayed in the main window too, it's not hard to locate the SD card in the graphical designed partition software)
3. In the new popup window, we need to specify file system, cluster size and drive label;
4. Click OK and Commit

After format completed, Partition Expert will reload disk map, now we can check if the SD card capacity shows right or not.
