Now, I did use my old PNY 2GB flash drive I use for repairing computers and was able to play Luigi's Mansion on it with out a problem, but I formatted it to FAT16 Cluster Size 32KB. My External 320GB Western Digital HDD has the GC games partition as FAT32 32KB Clusters. I wonder if that's what's causing the problems. I'll edit this post later OR make a new one detailing if changing the partition's format works. Cause all my other flash drives formatted to FAT32 don't work either, the only one I formatted to FAT16 ends up working. :U
      Ummm, what? How's compressing them make them unplayable? Lol only certain games won't work compressed but most do...trust me, I use compressed/scrubbed GC and Wii games and 99% of them work compressed. Though you are right, games can be played without using DiscEx...it's entirely up to the person if they want to use that program.

      Anyway, if your GC games are on a separate partition that's probably the cause. The GC games need to be on the primary active partition, you can have all your Wii and GC ISOs on one partition.

      My GC games are on the Primary partition and my Wii Games are on a logical partition formatted to WBFS and they work fine in USB Loader GX and WiiFlow.
      I heard that a lot of games using DiscEX failed, so I never used it, I know most games work with it but I don't see any point in using it unless I really needed the space.
      But if I was having this problem with EVERY other flash drive I have available at my disposal, then it's not an issue with how many partitions I have because each one of those flash drives don't have partitions. The issue was that FAT32 wasn't working for me and I had to format to FAT16 w/ 32KB Clusters. But FAT16 only works on 2GB and lower, so there's no way to partition a HDD to FAT16. I'll need to see if I can find a way to get games to work from the HDD instead of just the flash drive.

      It's weird that FAT32 with 32kb clusters isn't working on your HDD, it's possible your HDD just isn't compatible. I've heard WD has issues with certain Homebrew programs.

      What program do you use to format? I've always had luck with EASUS, if you haven't already you may want to consider trying that.

      I thought that too, but then I have four other flash drives that don't work the same FAT32 32KB Cluster setup.

      I've never had issues with Aomei Partition Assistant, I used to use EASEUS, their practically the same, but Aomei has features I like and a better looking UI.

      I have two flash drives that work, one using FAT16 @ 32KB Clusters and the other FAT32 with 16KB Clusters, both work flawlessly. One is a PNY the other is a Philips 2GB.
      I'm going to change the other primary on my HDD to FAT32 16KB Clusters and see if that does any good. Gonna take a while backing up all the data then copying it back.

      Most Portable/External HDD's use Western Digital HDD's because their reliable and heavy duty, I have never had a bad WD drive before, ever, but I have had countless Seagate's and Hitachi Travelstar's go kaput on me, specially Seagate. Though Seagate promised better HDD's so I gave them another chance and currently use a 1TB in my desktop and so far so good. Also, most of the time, the Wii doesn't like the SATA-to-USB or IDE-to-USB bridge controller, doesn't have much to do with the HDD itself.

      I've always had good luck with my Seagates, but a couple people I know had WDs and had them die after only owning them a year....but I also know people who have WDs and have no issues at all so who knows. In either case it definitely is strange that your HDD and some other USB devices aren't working right with this using FAT32 32kb clusters, when you said that some are. Wish I could help you out here but I'm not sure what else to say about it, it's oblivious the HDD is having issues with either the program or the Wii itself. Hope you can solve the issue.

      Just because your wii games are on a logical partition does not make the fat 1st partition. You have to make all partitions logical and change the fat to primary 1st plus active and then the other partition could primary as long as the fat is the first partition

      since I am having problems trying to edit my posts just want to mention that DiscEX never compress any of my GCgames you need GCReEx to compress it and in fact if you compress it with GCReEX, DiscEX says it is under-dumped so I do not compress any of my GC games and I still use DiscEX and all my GCgames works perfect and it does not matter how many partitions you have on the hard drive primary or logical the FAT32 has to be 1st partition for GC games to work
      2TB WD, Ist partition FAT32 primary plus active, 2nd partition NTFS primary for the 1st Wii
      1.5TB Seagate, one partition FAT32 primary for the 2nd Wii
      500GB Toshiba, one partition FAT32 primary for the Wii, Xbox360 or PS3
      no issues with all three hard drives all Wii and GC backups and homebrew works perfect, do not even need a SD card

      since wad manager1.7 does not let me install wads from USB, I sometimes use wad manager 1.8

      Acronis Disk Director 11 Advanced and MiniTool Partition Wizard changes the cluster size without formatting your drive you do not lose your data plus it is very quick, I made a backup of the homebrew stuff and remove it from the drive but I left all the games and movies on the hard drive and I did not lose any and they all work perfect after I change the cluster size from 64KB to 32KB then I put back all the homebrew stuff usually what you keep on the SD back on the drive so I do not need the SD card in the Wii

      I usually compress my games to save space but always keep the 1:1 backup in case the compressed ISO doesn't work.

      So I have the usb loader gx r 1200(iso249) with d2x v8 iso56 and Dios Mios v2.2(iso249)
      When i get to usb loader gx i click the game (Im pretty sure I have all the setting right.) and it starts to load.
      It gives me the same DML cant use no disk feature or w.e (The same thing SNES got earlier in this thread but I couldnt find it to get the fix.)
      And then it goes to black, after a few seconds the Dios Mios screen pops up. Then black again. And i waited a few minutes and nothing came back. (These im trying to play from an hdd btw)

      Ive been working at this stuff for the past two days and have become more familiar with everything thats actually going on. Any help would be wonderful.

      My isos that I am using I used usb loader gx to rip from the disks to my hdd. I have the compression settings on in the usb loader.
      (I only have 4 games, Luigis mansion, windwaker, sm sunshine, and pikman)
      Im using a 320gb wd passport. one of the older models.
      Ive tried reinstalling both the usb loader and dios mios. Have not tried the cios because im not really sure what it does.


      Thanks for any help ive hit a dead end. My final idea is try some other gc isos im going to try that later.

      Thanks again

      Go to the main settings section (gears on the bottom left) then look for the "NoDisc" and "NoDisc+" settings, turn them both OFF, and make sure all your games are set to "Use Global" for those in the individual game settings.
      The cIOS doesn't matter for GC games, only cMIOS, MIOS, DIOS MIOS etc etc.

      Make sure your HDD is formatted correctly (FAT32 32kb clusters) and make sure your GameCube games are on the primary active partition (I recommend using just one FAT32 32kb partition anyway as you don't really need 2 partitions if the HDD is just for Wii). Lastly you can try re-ripping the games with CleanRip and using the clean ISO image (just name it "game.iso" and put it in the correct folder location) some people have cited having issues with DiscEx.

      So no disc thing worked. It doesnt give me the error message.

      I tried Luigis mansion this time and the wii just turned off after showing a black screen.
      Could this mean there is a problem with the Dios Mios or could it be just a bad iso.

      Im going to try the cleanrip program now.

      And just for more info I am using a fat32 drive with 32k clusters and there is only one partition ont he drive I used the EaseUS partiton program to make it primary and active which I dont think i needed to but w.e.

      It could be a bad ISO, Do any other GC games work for you? Also are you running the game through DiscEx?

      I am not running them through DiscEx. I just did a cleanrip of windwaker. I then plugged the hdd to my computer and changed the file names and root to match what you need for gc games.
      /games/Legend of Zelda The Wind Waker[GXXXXX]/game.iso (i forgot what it was but clean rip gives you the game code)

      When i ran it through usb loader gx I got the dios mios screen and it faded out to black then nothing... it shouldnt take more than a min or two right?

      Thanks SNES

      Try making the game path like this:

      USB1:/Games/GZLE01/game.iso

      Don't include the name on the folder, just the title ID as my example shows, see if that works.

      And no, with DM you should see a big GC symbol and only have about 10sec wait...how are you loading USB Loader GX? HBC or Forwarder channel?

      I am not running them through DiscEx.

      Just ran cleanrip on wind waker. Any way to have clean rip root and name the gc Iso correctly?
      Also when I ran cleanrip it searched for updates and I guess could not get on the internet. Is this bad? I have Ethernet plugged in through an adapter.
      At the end it onyl told me it could not verify it with xxx.xxx (sorry dont remember the file name i shouldve wrote it down.)

      but anway I plugged my hdd into my comp and canged the file name and root
      USB:/Games/Legend of zelda the wind waker[GXXXXX]/game.iso (again sorry dont remember the game code but cleanrip gives it to you)

      I tried to run it with usb loader gx and the dios mios screen came up then it faded to black. Then nothing for about 2-3 min. It shouldnt take longer than that. wii was unresponisve so i just held the power button.

      Any advice? I feel like I am very close....

      Thanks SNES

      sorry for the double post I thought it didnt work.

      I was using a fowarding channel so Ill try both of those now

      CleanRip has no settings so unfortunately you get what you get, you have to do the renaming yourself or allow DiscEx to do it for you. The update is for the dat files, not really necessary. As long as it gave you a message saying it was successful the rom should be good, it just wasn't able to check the md5 to make sure...also try launching via HBC and see if that helps.

      ok thanks.

      So now i tried it through homebrew and a fowarding channel and they both come up wiht the GC logo with DM under it and then cut to black and nothing.
      I can figure out what is wrong. I might try to reinstall DM2.2 or something like that. I was going to install 2.1 but I cant find it anywhere, jus tto see if that was the problem.

      I've gone through about six Seagate HDD's, for some reason about a year of use they start to make noise and about another year after that they lock up. I've seen my share of bad WD HDD's, but I've just never experienced it myself, I still have both my first WD laptop HDD's I used in a desktop build about 4 years ago, that desktop still gets used to this day. I also put a Seagate Barracuda 160GB in it as well for backup purposes. My guess is that those devices go into a sleep state once you get to a certain part of the game, usually after the first few opening cut scenes of first party Nintendo games. I have an old Kingston 4GB that I tried this on and it actually froze the Wii when USB Loader GX tried to initialize the USB stick. That Kingston never did like consoles, works on PC's just fine though, must be the way it operates that consoles don't like.

      since wad manager1.7 does not let me install wads from USB, I sometimes use wad manager 1.8
      You mistake what I've said, in Aomei Partition Assistant I set the main partition with my GC games on it to the Primary partition and it's already set as active, then my logic partition is the WBFS format. The reason I have it split like that is to use the main partition as file storage for everyday use plus my GC rips and use my WBFS partition for my Wii rips. Like I had said before, usually it's not the HDD that causes issues, it's the controller/bridge it uses that has issues. My external works fine for everything else on the Wii including Wii rips, music and my ripped DVD movies played through WiiMC.

      Theoretically that should work fine, but it doesn't, so I'm going to see if formatting it to FAT32 with 16KB Clusters works, because both other flash drives that work are running 16KB clusters.

      Yeah, I guess it's just luck of the draw sometimes. I've been using a 1TB Seagate for at least 3yrs now and had no issues (well, VBA GX tried to save to it while the drive was sleeping and corrupted the whole damn thing lol) but I was able to recover the data and have no more issues, I just make all my apps and such save to SD now. Anyway, 16kb clusters is also acceptable for DM, it's just anything above 32 that won't work. Again, I wish you good luck in solving the issue but I think I've reached the peak of what I can offer for advice and assistance lol.
