    Whenever i use Decrypt9wip to backup my new3ds's nand(no matter the sysnand or emunand),it always takes me so much time even more than 2 hours. Because the backup process usually takes several minutes to run 1%. And sometimes,the 1% to 30% or 50% is normal, but the left 50% or 70% is too slow!!! i don't know the reason,but if the process is always slow, i will crazy!Who could help me? Thank you so much!!

    Is your SD card not class 10.
    Also, is it an authentic card?

    It sounds like an SD card problem.

    Backup your files and format the card with sd formatter 4 with format type full erase and size adjustment on in the options menu then try to backup the NAND with D9 if you still cant do it or takes forever you have a fake or dying SD card.

    Don't forget to backup your emunand if you have one using emuNAND Tool

    You would format it completely like I said above and the run it through h2testw and do a write+verify test.
