    Try 'select volume 5' then 'select partition 0' and then 'assign'

    That's really strange. Can you take another screenshot?
    Edit: If you list volume/partition again, are they both selected?

    Tried that, apparently emunand is a unlocatable file in the sd card and thats why we need to use a image tool to copy every single thing on the card. That way we can transfer emunand to another card, the EasuUSPartition allows you to combine the partitions as the card will read the image as a partition.

    Also i need a little bit of help, whenever I try to merge the partitions it shows me an error, can someone help me with this or show me another partition merge program for fat32?

    Also, is the important information only for that type of CFW? I have arm9loaderhax and don't know if that info also goes for it

    Since I did not see anything for Linux users yet I just wanted to point out that this works just as well.

    1. Make a bit-perfect copy of the old card using dd (or gdiskdump if you want a progress bar):
    sudo dd if=/dev/<device-ID of old sd-card> of=sdcard.img bs=1M

    2. Copy the image to the new card:
    sudo dd if=sdcard.img of=/dev/<device-ID of new sd-card> bs=1M

    3. Use gparted or something similar to adjust the end cylinders (partitions) like described above.

    4. Enjoy

    Be absolutely sure of your device IDs so that you don't break anything, you can look them up in gparted.

    @Zaazu Feel free to put this in OP if you want. ^_^

    A9LH is not exactly CFW itself but a bootloader as far as I know and should not be affected by the sd card at all, though since it has to boot into something I would check what that something is first.
    Generally speaking this method should preserve whatever setup you have on your card, not just Luma.

    Um when I do all the steps or whatnot the partition size doesn't change to the size of the new SD card. It still stays the same (1.83 GB)

    Hello. Can you please help me? I've done everything by the instruction, but there's no button "Move/Resize" in the partition manager (see screenshot). Any idea what might cause this?

    Upd.: Nevermind, used another program (MiniTool Partition Wizard) and it worked without problems.

    hello. did you manage to fix your issue? I'm having the same problem where my SD card refuses to assign a drive letter to the actual partition.

    Instead, it keeps assigning to my emunand portion which I can't read on my pc.

    i have done this successfully before, just wanted to ask, would this still be possible to do if i wanted to move from 64gb to 32gb? do i just have to make sure that the contents of the source 64 can fit in the 32gb card?

    If you want move content from a SD card to other SD card with less space, you have make sure the files can fit in the SD card with less space (obiously)

    I have the same problem as this person. When I tried to resize my partition on my sd card from 16gb (the size of the image) to 64gb (the actual total space on the sd card), I got an error saying that there's a problem updating the FAT directory entry. I am 100% sure that my SD card isn't corrupt as I can still play the games on the sd card on my 3ds. Additionally, the applying of changes will stop at 72% before the error pops up.

    Edit: I'm wondering if it has something to do with the allocation unit size? Because my SD card was originally ex-FAT and I formatted it into FAT32 with a cluster size of 512 bytes which isn't the recommended size for a FAT32 partition (but I still did it anyways to save space).
