It's probably the umpteenth time someone's had problems with Dios Mios, but I had to ask somewhere. I've been using Dios Mios with CFG for a few weeks. At first, I used a microSD reader because I didn't have a spare HDD to use. I recently bought a Hitachi Touro 1TB portable drive to use as a backup for my laptop, so I decided to use my old external drive for the Wii. Now, Dios Mios worked perfectly with the micro SD, so I assumed it was set up properly. Anyway, I checked the external drive to make sure it had 512kb sectors, formatted it FAT32 with a 32kb cluster size, copied everything off the micro SD reader and..........it didn't work. CFG USB can read what's on the hard drive and it can see the games, but when I tried to load them, it just went black, with no splash screen. The drive itself is an old Western Digital drive in a cheap Yum Cha enclosure. I thought that the enclosure could be the problem so I tried using the Hitachi portable HDD I bought recently. I wasn't planning on using it with the Wii, but I checked the Device Compatibility List in the Wiki on here before I bought it and it said that it worked with CFG USB Loader, so I thought it would be a good Plan B to use if I couldn't get my external drive working. Anyway, I checked to make sure it had a 512b sector size, formatted it FAT32 with 32kb clusters, copied everything across and........no good. I still have the same problem I had with the other drive. CFG USB will see the games, but it will go black as soon as I try to play them. I did adjust some settings when I was trying to get the hard drives to work, so I thought that that might be the problem, so I checked the micro sd reader to see if it still worked and (surprise, surprise) it worked perfectly. While I was looking I found an old 512mb USB stick and just for good measure, I decided to throw a gamecube game on it and sure enough, it worked as well. Anyway I thought, if the HDD's are having problems with gamecube games, they might have problems with wii games as well. I formatted both HDD's as WBFS, used WBFS Manager to copy some wii games onto them and they worked perfectly. Then I thought it might have something to do with formatting, so I formatted both drives as FAT32 and used Wii Backup Manager to copy some Wii games onto them and they both worked. At this point, I thought it wouldn't hurt to try Dios Mios again, so I copied some gamecube games onto the drives and......same problems again In short (for those too lazy to read): Both HDD's work with Wii games on a WBFS partition Both HDD's work with Wii games on a FAT32 partition Neither hard drive will work with Dios Mios, but both the micro SD reader and the USB stick I used work perfectly. Anyone got any ideas? I'm using the latest versions of Dios Mios and CFG USB Loader and I'm using CIOS 249.
