How to use a larger than 2TB Hard Drive on a Wii as a Single FAT32 Partition

*The Issue: [SOLVED] How can I use a larger than 2TB GTP Hard Drive on a Wii as one single MBR FAT32 partition? [SOLVED]


***
Make sure to see the potential issues with EmuNAND and FIRMWARE noted below ***


This is a twice boiled down version of a couple previous posts from several years ago. This question comes up from time to time and rather than constantly referring people to my 5 year old post that I have to hunt down and that is a bit convoluted talking about various drive sizes and processes, I thought maybe it would be better as an original tutorial that is more to the point and easier to find. One of those previous posts from 2016 can be found here: http://gbatemp.net/threads/usb-loader-gx.149922/page-1129#post-6662953

Here in this revision I focus mainly on using 5TB Western Digital drives because all NTSC Wii, NTSC GameCube & non-NTSC PAL/JAP titles will fit. You would be best to read through everything a couple times to understand the process before proceeding with the steps. While there are other tools and processes others may have come up with, the following is the process I have used myself many, many, many times over. Feel free to seek out other alternatives as you see fit.


Potential Issues:
  • EmuNAND - It has been reported on 10/28/21 by a user that EmuNAND does NOT work with this method using 64k or 256k cluster size. This would be a problem if you are trying to have EVERYTHING work off just the HDD and do NOT want to use an SD card. At the moment the only choices seem to be:
A) Use EmuNAND off an SD card large enough for your needs​
B) Use a 4TB or smaller HDD formatted with the 32k cluster size​

  • Drive Firmware - It has been reported on 06/01/22 by a user that a 5TB WD My Passport purchased around May 2022 was not recognized by the WD Quick Formatter software due to the firmware not supporting the changing of the block size. I haven't bought a My Passport dive in a couple years and will have to purchase a few to see if I can replicate the issue so the pending questions are:
A) Will others run into this issue or is it more of a rare occurrence?​
B) Will this become an issue with any newly produced WD drive size because of current firmware versions??​
C) My version of WD Quick Drive Formatter is v1.2.0.10, what version is currently available for download on the WD site and would that make a difference?​
C) If new firmware becomes and issue can the drives firmware be downgraded to allow WD Quick Formatter to work?​


My Wii:

Original Nintendo Wii (not a Wii U), however I did have a report that it works for the Wii U as well. While I do have a couple Wii U's, I'm lazy and have yet to finish modding them to try it myself.


What I Recommend:

**06/09/22
Firmware on newer drives might be an issue. My recommendation listed below are previous to being made aware of potential issues**

I recommend Western Digital drives because there is WD software that indirectly converts the GPT drive partition to MBR. It has been found that most other drive manufactures do not work because they do not offer this ability, so my recommendation is to stick with using a Western Digital drive. This method has always worked for me on drive sizes of 3TB, 4TB, 6TB, 8TB & 10TB. I found there was no need to continue on with trying my 12TB & 18TB drives.

5TB is the sweet spot, but any size 3TB+ Western Digital drive should work. I have personally used MyBooks, Passports, and the P10 Game Drive. Others have told me their Essentials & Elements drive also worked. I will include additional information as needed for the different drive sizes I've used, but for me the sweet spot is the 5TB because it will hold all NTSC Wii, NTSC GameCube titles, PAL and Japanese titles that did not have a NTSC counterpart, and those that have various versions released.

I do NOT use EmuNAND off the HDD because it has always been installed to my 256GB SDXC card. There is a report that EmuNAND will NOT work on a 5TB+ HDD using this method. For more information in this issue see the "Potential Issues" area below.

Recommended External Drive (one of the following drives and a Y-cable):
or​
These drives will most likely work with the regular cable, but you never know if your ports are weak on power, so for a few bucks it’s always nice to have a Y-cable on hand in case it is needed:


The Basic Steps (using a Western Digital Hard Drive):
  1. Merge all items on WD HDD into 1 partition
  2. Converting the GPT partition to a MBR partition
  3. Select the proper cluster size and format the entire drive as FAT32
  4. Optional - Set drive to as ACTIVE & PRIMARY
  5. Some of my programs and setting in use
  6. Links to Wii items I feel helpful
  7. Thanks to those over the years who have helped me with this quest
  8. Miscellaneous pictures


The More Detailed Steps:

1 - Merge all items on WD HDD into 1 partition

-Using EaseUS Partition Master (or the partition manager of your choice) check the drives partitions:
-It is very important you merge any other partitions showing such as unallocated, hidden, marked with an ASTERIX, or ??
-Picture below shows what I am talking about on Drive C, all of these need to be merged
-Merge any and all into the main partition, you want just one partition showing and nothing else at all
-Link to free version of EaseUS Partition Master: http://www.easeus.com/partition-manager/epm-free.html

2 - Converting the GPT partition to a MBR partition

-Using EaseUS Partition Master (or the partition manager of your choice) check the drive to see if its partition is MBR or GPT:
-If your drive is MBR skip this step and continue onto step 3
-If your drive is GPT, less than 2TB and you want a free partition manager tool go to step 2a
-If your drive is GPT, less than 2TB and you want a paid partition manager tool go to step 2b
-If your drive is GPT, a Western Digital drive & larger than 2TB go to step 2c


2a - Change the GPT drive partition to a MBR partition if your drive is 2TB or less:​
-Free tools to aid in this conversion:​
  • To be added as I find them

2b - Change the GPT drive partition to a MBR partition if your drive is 2TB or less:​
-PAID for tools to aid in this conversion:​
  • EaseUS Partition Master
-My free version did not have this option but my paid version does since v12 and up​
-Changing the WD drives partition above 2TB will not work using this method, it has the 2TB conversion limit, so go to step 2c if your drive is larger than 2TB​
-If you find more recent versions offer more functionality please let me know and I will update this post​
Convert GPT to MBR.jpg


2c - Change the GPT drive partition to a MBR partition if your drive is larger than 2TB using WD Quick Formatter:​
-Note: This most likely will not work on a hard drive that's not made by Western Digital, it scans for compatible drives automatically.​
-If using another manufacturer you will have to search to see if they make tools for something similar​
-Used to convert a larger than 2TB HDD to be Windows XP compatible​
-Once running WD Quick Formatter click on CONTINUE then ACCEPT and it will scan for drives​
-Available drives will be listed and if there is more than one select the correct drive to format​
-For configuration select XP COMPATIBLE and then click FORMAT DRIVE
-Important: In doing this conversion it formats the drive to one single NTFS partition and changes the partition table from GPT to MBR​
-I'm on Windows 10, maybe it makes a difference what OS you are on when you run it, but you might get an error​
-Using this on my 4TB Passport & 5TB P-10 Black Game Drives I received an error about "no recognizable file system on the drive", just click OK and let the format finish and once complete click FINISH
-This process can take several minutes but it did finish so give it time​

3 - Select the proper cluster size and format the entire drive as FAT32
-Use FAT32 GUI Formatter to format the drive to FAT32:
-Original links seem to be working again (http://ridgecrop.co.uk)
-32-bit Link: http://ridgecrop.co.uk/index.htm?guiformat.htm
-64-bit Link: http://ridgecrop.co.uk/guiformat-x64.Exe

Cluster size will depend on the size of drive you are using. If you use a different cluster size the entire drive may not be accessible and I would recommend reformatting using my recommendations below:
  • 4TB and smaller drive: Select 32k clusters (Allocation Unit Size: 32768)
  • 5TB to 8TB drive: Select 64k clusters (Allocation Unit Size: 65536)
  • 10TB drive: 256k clusters (Allocation Unit Size: ????)
  • 12TB & Above: Unknown, I never tested past 10TB

4 – (Optional) Set drive to as ACTIVE & PRIMARY
-Using EaseUS Partition Master set the drive as ACTIVE & PRIMARY:
-Some say this is not needed, but I always set my drives as ACTIVE & PRIMARY
-Worse case this has no effect so I still do it anyways

-Yes I have about 32 Wii's just for myself (4 of each type plus my test Wiis) and over 210TB in external hard drive space I'm constantly fiddling with. It would seem that my OCD has ADD making me obsessively collect randomly.

-WD White/Black 5TB Passport -0B: Successfully Converted and Working
---Purchase Link: https://www.ebay.com/itm/366016543562

Purchased, converted, and successfully tested a used Western Digital White/Black 5TB -0B Passport drive this weekend. So the -0A vs -0B might not be the identifier for the firmware issue, or there might be newer firmware versions then this. I'll go back through this thread and see if I can get more information from anyone that was having issues converting their drive. Maybe I can find someone around that can send pictures of their drive information.

Drive was purchased used off eBay for a decent price. Hard to find these to match the Wii colors these days. It contained only one GPT partition without any other fragments. WD Quick Formatter recognized it right away and allowed the MBR conversion. WDQF did throw the now usual "drive not recognized..." type error during conversion, but after dismissing the pop-up the drive finished conversion successfully. FAT32 Formatter didn't have any issue formatting to FAT32 32k. I tested it with both Wii & GameCube games which loaded up without issue.

I have the following drives still on order (so they match the color of my Wiis) and will update you once these arrive:
1) eBay New Black WD 5TB -0B P10 Game Drive: Arrives tonight 12/01
2) Amazon New Blue/Black WD 5TB -?? Passport: Arrives 12/02
3) eBay New Red/Black WD 5TB -0B Passport: Arrives 12/05
4) eBay New Black/Black WD 5TB -0B Passport: Arrives 12/06

I think after I test these drives I'll venture over to updating my cIOS's to d2x-v11-Beta3 and my loader apps to current versions in use. But one step at a time, I don't want to F up my setup, so one little change at a time incase something breaks compatability.

You'll need to ask users with this problem things like:
- What software did you used to format your drive?
- What version of the software you used?
- What OS / Architecture?
- Brand?
- Life time of drive?


In my experience, making bootable usbs with Rufus 3.X ≠ making bootable usbs with Rufus 4.X ≠ Using different isos.

Yes it does get complicated. However there are specific instructions on Page 1 that need to be followed. I have only certain Western Digital drives working through this method and WD Quick Formatter and FAT32 GUI Formatter seem to work in getting them setup correctly. I'll need to add in a list of working drives and alternate software going on from here.

Work has recently started to open this up to almost any drive by using exFAT, There has been some success just recently reported along these lines, but there is still a lot of testing to do and software to be updated. The goal is to get 64-bit addressing integrated and future proof things. I'm just helping as I can, the heavy lifting is being done by @blackb0x.

A portable 5TB is the sweet spot so it can hold all Wii & GameCube titles. Current drives that I have working are:
-Western Digital Passport Older 4TB:
-Western Digital Passport 5TB:
-Western Digital P10 Game Drive 5TB:
-Western Digital MyBooks 4TB, 6TB, 8TB & 10TB (in both the older and newer versions)

I believe I had reports the the WD Elements were also working, but I never kept a list. Then we ran into WD drives that were not working but I never got info on them. It was thought at the time a new firmware version or new drives being used in the enclosure was causing the issue. So that's why I'm trying some other later model drives to see if I can find one that doesn't work. I think from here on out keeping track of specific information will be helpful. I'm going to make a list of what I have and then add in working/non-working WD drives from others as we move forward.

@XFlak & @blackb0x - Another couple days and 3 more fully working 5TB Western Digital Passports. Man I have no luck at all getting them not to work, lol. Maybe it's not me and whoever didn't get them to work was doing it wrong. Oh well, I needed the drives anyways. Maybe the next drive I get will be a WD P10 6TB.

This time all new Black, Red & Blue drives to go along with my White drive a few days ago to match the Wii colors. Not enough time for me to write out the information so I'll edit this later to include it, but pictures are attached below if you're interested in knowing.

Hey everyone! I would just like to throw my 2 cents into this thread as I have successfully converted over 30+ WD drives over the years. I unfortunately just came across this and wasn’t recording any of the exact model or firmware numbers while formatting these drives. I have successfully formatted a variety of 4TB and 5TB WD Passport drives as well as 5TB portable WD Elements drives (possibly some 4TB elements as well, I can’t remember) with 0 issues. I haven’t come across a single WD drive that would throw the error using the WD formatter and Fat32format GUI method other than some fake WD imitation drives that were sold to me. They looked like the real deal, packaging and all but would not be recognized by WD formatter. I’m not sure but possibly some peoples issues were from fake WD drives. I’ll start recording model numbers and firmware from now on to contribute to this list and to figure out if it has been user error, fake drives or if there are actually incompatible WD drives out there.

I’m also very interested in putting together a list (if there are any) of portable sea gate drives. Using the method from this seagate 2TB+ thread. I checked a SeaGate
Capacity: 4TB
Model: SRD00F1
P/N: 2AWAP2-500
S/N: NA9SEXD7

It came back with the only having 512 supported sector size to which in my understanding means it’s not possible with this model and method. I will try other SeaGate drives and report back with my findings. I encourage others with >2TB SeaGate drives to try as well. It would be great to find a broader list of HDDs outside of current WD drives that are confirmed working.

As for the ID spoofing, i’m not sure if this method would change anything for the SeaGate drive that came back with only 512 supported. Is it worth testing the spoof method on this drive or useless due to the 512 sector limit?

Last thing I would like to bring up is this old fork of CIOS I found. It allows you to use a dual harddrive bay set up with the WiiU. This way you can avoid having 2 partitions on one HDD/SSD or using two separate drives with one partitioned as ntfs for Wii U and one as fat32 for vWii with stealth. This CIOS fork allows the use of 1 USB port for 2 HDDs/SSDs with an externally powered bay. Before if you wanted 2 drives that meant all 4 USB ports (Y cables) or two externally powered drive cases and 2 USB ports. It’s been years since I messed with this and truly never saw it through to test all aspects of the set up. I got it working to the point where I had two 2TB SSD’s in an enclosure, with one NTFS for WiiU and one Fat32 for vWii. If i’m remembering correctly it eliminated the need for Stealth in the fat32 drive as the WiiU never saw the fat32 drive, it only was detected by the vWii. I never got around to finding and testing 2.5” drives larger than 2+TB with this set up. I’m not sure if it would allow a bypass for the 2TB limit of the WiiU at least on the vWii side of things. Even if the 2TB still exists for the vWii side this set up is so seamless. @XFlak I did bring this up to you in a DM in 2024. Do you know if the fork was ever merged or planned to be merged into CIOS? I’d like to start messing around with it again. I did very minimal testing past the drives being recognized separately. Another user @caleb39411 seems to have done more testing and ran into some issues. This would be awesome to revive as it seems like one of the most seamless ways to have a WiiU vWii set up. If anyone is interested in this I can provide my enclosure set up and help with testing. Unfortunately I’m not versed in coding or any of the technical stuff involved in working on this but I am more than happy to help test. The original creator of the fork has been inactive for years and it would be a shame for this project to die. Let me know your thoughts everyone. Cheers.

Bro u said so much, sorry if I don't answer everything right away, trying to get kids to bed right now

These days Aroma has a built in option to toggle on or off the format prompt for fat32 hdd's while in WiiU mode

Also I think this might interest u. It's related and is promising :)

Haha yea sorry, I had a lot to say about the topic. I’m not sure how I missed that thread, would have saved a lot of typing lol. After reading it that seems very promising and eliminates the need to test old drives if it ends up working. That would be amazing, i’ll keep an eye on that for sure. As for the updates in the WiiU modding, that’s awesome aroma has been updated that you don’t need stealth anymore. I haven’t been keeping up at all with aroma and Wii U updates. The dual enclosure bay still seems, in my mind, the best way to do it. What are people optimal set ups on Wii U these days? Can you use 1 large drive between WiiU and vWii or does it have the 2TB limit?
 
ModMii now supports the WiiU and vWii in addition to Wii these days, but it doesn't cover this setup that may interest u (modmii supports the typical Aroma installation, in-line with the hacks.guide site)
Oh that actually might be perfect! I’m going to try a setup with this and see if does what I was envisioning the dual enclosure doing. Thanks for the help.

Just a bit of advice for people having the same issue as me.

I couldn't get my AF format drive into 4K logical sector mode no matter what I did, as I absolutely require full use of the 3TB drive I am using.

It's an AF drive with 4K physical sectors. Shouldn't be an issue, right? These are 2015 drives, so surely not any issues akin to the newer disks not allowing this sector change either?

Not always. I'm here to tell you about an outlier. There are 2 generations of 4K emulation, my drive has Gen 1. 512e only, nothing else. Absolutely cannot format it to 4K logical sectors. No tool works, even SeaChest Seagate's own tool.

Gen 2 allows this change to 4K logical sectors.

Spent about 6 hours on this today. Hopefully saves someone else some time.

Using these Gen 1 AF 4K drives, or any HDD that doesn't have support for 4K, use an ASM1153/ASM1153E USB 3.0 enclosure. They support 4K emulation and allow these drives to work perfectly with the Wii in FAT32 MBR mode up to 16TB. If you have an external HDD that won't format 4K, shuck it, spend $26 on one of these enclosures and your drive will work with your Wii in FAT32 MBR mode.

Hope this helps someone in the future.
You sir... You just saved me SO much time. I'll be posting my own guide to achieve something similar like this.
Post automatically merged:

Wanted to share an updated, complete solution here since a lot of this thread predates some of the tooling that now makes this reliable.

I put together a full writeup covering a working setup for any AF (512e) HDD, not just specific "lucky" drives, using an ASM1153E dock flashed with the correct config to force 4K logical sector reporting. This finally gets past the 2TiB ceiling in a way that's consistent and repeatable, rather than depending on finding a drive with the right firmware quirks.

The guide covers the full process end to end: flashing the dock, partitioning with gparted (GameCube / Wii / Wii U as three separate partitions on one drive), the Wii U side (Stroopwafel + USB Partition plugin), and a couple of graphical bugs (Wii U Data Management and USB Loader GX) that look like real limits but aren't.

Full writeup here

Happy to answer questions if anyone runs into snags following it.
