Windows 10: 64GB microSD card - want to format with one large partition but can't

I'm currently struggling to format a 64GB microSD card. I've been into disk manager, etc but can't seem to be able to create a single partition - the minimum it will let me create is two (one of those is 2GB) but when I've done that and put the card into my PC I see FOUR partitons (F, G, H, I) when I click on 'My PC'.

I've tried deleting these, creating new ones, re-formatting, etc but I can't seem to create a single large partition.

I also need the partition to be formatted as exFat.

Any ideas please where I'm going wrong?

The card is a SanDisk.


Thanks

:)

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!
