Windows 10: Formatting Removable Disk

Good Day! I just wanna ask how do I fix an SD card that has unallocated space. I try merging two partitions but the "extend volume" option is greyed out. I have tried creating a new volume but they don't merge. Thank you!

How To Format A Write Protected Flash Memory ?

¿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
8. assign
9. exit

with that commands you will format the flash drive in fat32, if you have a large drive you can select also "format fs=ntfs" in step 7.

good luck!
