My SD Card Van easily handle 30 MB write speeds (seq.). So it shows how weak the internals in the Wii U are.
30mb speed only happens if big files are written at once.
If you're dumping MLC, process will be way faster with SDCard that can output bigger speeds with small/huge files.
Autocorrect is working correctly /s

I just dumped everything. When I Tried copying the last part of my MLC to my PC, I'm told it's corrupt and it won't copy. Is it actually corrupt or does windows just having some other kind of problem? Either way, I'll try again so I can hopefully have a successful dump. If I brick my Wii U, is the MLC an important part of being able to recover it?

A few more details, I barely have anything on my SD card. It's 32 GBs, so it should be large enough to hold it. I let it run for a couple hours while I did stuff around the house. When I came back, the Wii U was sitting on the home screen so I assumed it finished successfully.

Yes, MLC is your Wii U nand.. So it's every important, all files stated are important.

No, I have the deluxe black edition. The post I read said a 32gb sd card was big enough to dump the nand. I was under the impression that you couldn't use SD cards bigger than 32gb with the Wii U.
at least here a 64GB card worked fine for my 32GB Wii U. The 32gb is sufficient for your needs. try another run.

Trying again yielded the same results. I found other information saying I could use larger cards. I had a 64gb sdxc card laying around and was able to get it formated properly. That gave me what I needed and, as they say, the third time's the charm.

I tried dumping the MLC of a Premium WiiU on a 32 GB SD Card. It ended up on the WiiU menu and the SD Card is completely full (0 bytes free). All there was on it before the dump was the HBL and NAND Dumper so it was as good as empty. I guess a 64 GB Card is needed for the dump.

I made the 2 run copy thing. Now i have all files. After copying mlc.bin files i have 100 mb free space on the SD. I dont' know if this work when i try to rescue the WiiU. I think for the rescue i need a 64GB SD Card.
Now i ordered a 64GB big card. But for now i made the 2 run thing.

Update: The 15 part is again broken
Error during copy to PC HDD
Now i have to wait for the 64GB Card :(

Flashing corrupted MLC is not a good idea. In the worst case, it might not even boot at all.
Just grab 64GB SDCard or remove some games from NAND partition. The more you have, the more space MLC dump will take.

    @K3Nv2 Snow Day is pretty fun. My only bitch would be the camera controls, when you move around, say down, you have to move the right stick left or right to get camera to turn and get your view, other than that I like it so far.

  • BigOnYa @ BigOnYa:
    I just been playing offline, and they give you a few bots here n there on your team to help battle. I don't think it's as funny as the other games tho, more battle oriented than humor, which kinda sucks, but I'm still early in it
  • Xdqwerty @ Xdqwerty:
    @BigOnYa, doesnt the game have a campaign mode?
  • BigOnYa @ BigOnYa:
    Yea, and co-op, but you can also start a pvp session and battle just with friends. You get special skill cards (powers) the more you play. And higher value cards, but you can only enable so many cards at a time.
  • K3Nv2 @ K3Nv2:
    If you can find enough for it
  • BigOnYa @ BigOnYa:
    Toilet paper is considered the money, you collect and buy stuff with TP, kinda funny. Graphics are def better than the other games tho, I think they used Unity 5 engine.
