Windows 10: microSD write-protected on one laptop but not the other?

[Windows 10 Home x64, v2004]

I tried to move some files from my laptop to my Samsung microSD, but Windows says it was write-protected. Checked the Lock switch but it was unlocked. Tried a registry tweak, and tried diskpart with the cmd line, but neither of those worked. There is no Group Policy Editor on Windows Home edition, so I can't try that. And I can't reformat the card because it's protected. I even tried putting the microSD into a different adapter, but no go.

However, when I put it in my other laptop [Windows 10 Home x64, v1903], it's perfectly fine. I can move files onto it no problem.

Any idea why one laptop would think it's protected and the other would not?

Write protected MicroSD card

After upgrading my 640 XL to Mobile 10 10586.218 from the previous Build, my MicroSD card seemed to become locked and/or write protected.

I noticed this, when apps weren't updating properly in the Windows store after the OS upgrade, backed up the files on my card to my computer, and have tried to format numerous times in my phone, only for it to time out, essentially not do anything.

I removed the card, placed it in a USB MicroSD card reader (came with my Lexar 128GB Card), and have tried using diskpart to remove the write protection, even though it states its successful, but when I try to delete the partition on the card, or try to
format it, it gives a read only error.

Also tried using MicroSD to SD converter, with the write protect switch off.

Any thing can be read from the card, but nothing will write, any suggestions on formatting or deleting the partition on the MicroSD card?

¿You already tried this one?...

Run CMD


1. diskpart
2. list disk

Then in the 3º step, put the correct number of disk in the list for the usb flash (if it's listed in disk 3, then you'll have to write select disk 3).

2. select disk #
3. clean
4. create partition primary
5. select partition 1
6. active
7. format fs=fat32
