This problem has been solved! Problem was the Transcend MicroSD, specifically the model TS64GUSDU1. While the WiiU was able to read and launch homebrew from that card, the dumper, or the console in general, was unable to write to it. So I've simply purchased a SanDisk 64GB MicroSD (SDSQUNC-064G-GN6MA) and formatted it as FAT32 with a cluster size of 64kb in order to make it work with the console. Ultimately, if you're seeing this and happen to have the same error as me ("Cannot write to the drive."), then it's most likely your SD card that doesn't play nice with the console. Hello guys! I'm basically experiencing the problem stated in the title. Now, to specify on what I mean exactly, I can't dump the NAND because CFWbooter is giving me an error. So after launching CFWbooter, I'm asked to simply hit the power button on the console to initiate the dump as you might already know. Thing is, after a few seconds, it aborts with the error "Cannot write to the drive." and simply reboots the console. I am using a Transcend 64GB microSD (TS64GUSDU1) with a generic, bland microSD to SD card adapter. The write-lock is not engaged of course. The SD is formatted in FAT32 (obviously) using a cluster/allocation size of 64kb. The fw.img file has been obtained from an external site whose name would probably violate the rules of this forum, basically meaning it was not compiled by me. If it helps, nothing else except for the SD card is inserted in the console. I've tried the following things already: - Reformatting the SD with a cluster size of 64kb instead of 32kb (primary partition) - Formatting the whole system - Use different microSD to SD card adapters (they are all the same function-wise anyway but one might could have had a bad pin or something, which is why I've tried doing that). Attached below is an image of the error. Do excuse the incredibly blurry and bad quality of the picture, but getting the camera to focus on only the text wasn't exactly easy. The white background didn't help with that either. Image Do any of you guys have an idea why this doesn't work? Is perhaps my SD card not supported? Any help would be greatly appreciated. Update: So I've noticed that while dimoks branch enables me to boot fw.img completely, I always get to face that "cannot write to the drive" error, which I'm currently blaming on my SD card. For some reason, FIX94s branch makes my fw.img cause a kernel panic, thus making the console crash to the home screen. I've attached a picture below documenting this phenomena. My wild guess is that the compiled fw.img of FIX94s branch contains a fatal bug. Maybe its fw.img somehow just compiled wrong for me though. Apparently this is completely normal and not in fact a kernel panic. This doesn't make things any different though because it still crashes to the home menu without any prompts to dump the NAND. I will now dig in said branch and see if I can get a revision of the project that could work for me. If I get no positive results, however, I'll just try a different SD card. "Error"
