How to format a write protected Micro SD card?

please help me to reformat my sd card

If your USB flash drive is write protected, possible solutions are as follows:

1. check that your flash drive doesn't have any mechanical switches on the outside of its casing, the switch can be fairly small, a little plastic knob, which can be easily overlooked.

2. Go to Start > Run > type in: regedit > hit enter. On the dialog box that opens up navigate to the following path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies

Find the entry named "WriteProtect" if the value is set to 0x00000001 (1), double click it and set the value to zero.

Reboot your computer and try your flash drive.

Note: if you don't have the StorageDevicePolicies folder, it might do good to create it and then create a DWORD key inside called WriteProtect and set it to zero.

3. You might have a malware/virus causing this problem. Do a thorough full system scan with a few programs that you have, if you don't have any security programs some of these might be useful:
Free anti-virus:
-avast
-AVG
-Microsoft Security Essentials

Free anti-spyware/anti-malware:
-malware bytes
-spybot search & destroy
-super anti-spyware

4. If the issue wasn't caused by a virus you might have to reformat your flash drive. The procedure is as follows:
Warning. Make sure you back up all important data from your flash drive. Formatting will cause all data to be erased

Download HP Format Utility to a folder on your desktop. With your flash drive plugged in, start the utility and select your flash drive to format. Once the reformat is done, you should be able to use your flash drive.

5. If you're still having issues try the following
Start > Run > cmd /k chkdsk :? /f > Hit OK
Replace the ? with the drive letter of your flash drive

6. If it's still not working, try formatting using this tool: Apacer Formatting Tool[/url
Unzip it to a folder on your desktop, make sure you only have the faulty flash drive plugged in, go into the folder and double click the start.bat. Make sure your flash drive stops blinking completely, after that, pull it out and plug it back in.
Try step 5 after this formatting tool as well.

If none of the above help you there could be two possibilities. The flash drive you're trying to write to was issued to be read-only type of media OR the flash drive is defective (you should return it for replacement to vendor/manufacturer).

Write protection should not stop a format at all. Are you getting any error messages when you format? Or just don't know how to start?

I'm getting error message "Windows is unable to complete the format." What should I do?

I just spent over an hour trying to format a ScanDisk 8G MicroSD card I bought a couple hours ago from Best Buy and I could see a drive letter but could not do anything with it. Finally I tried a different SD adapter and it was formatted in 2 seconds! The new bad adapter is in the garbage and I am moving on.

BTW: Trying to format cuz Android's new MTP usb transfer system is so much FUN to play with that the only way to win is to not play at all! I will transfer my files to this card! I don't care how long it takes! Actually, I have to transfer my videos and music to my laptop which has a card reader to transfer the files to the sd card since when it's in the tablet, it will just hang up and fail on every windows file transfer. Only media transfers from a media program like calibre actually work over usb.
