On Friday I bought a new 1 TB WD external HDD. I hooked it up to my Wii (without ever using it on the PC at all). I used a trick I found on another forum to be able to install the cIOS despite having updated to 4.0U without messing with WADs before. Then I used Waninkoko's cIOS rev10 and installed his SD/USB Loader 1.5. Everything seemed good so far, I was able to use the USB Loader to format the 1 TB HDD fine and I proceeded to dump all the games I had on hand that very night. A couple froze, but when they did I just restarted and eventually I got them all dumped - or "installed", as the Loader says. However, when I tried to run them, of the ones I tried, Wii Fit and Link's Crossbow Training actually worked during the few minutes I played. Other games had disc read errors or froze up within a minute, or usually seconds. Then I read that perhaps 1 TB is too big, and that to dump and/or play games properly I shouldn't be using anything larger than 512 GB. So on Saturday morning I formatted the HDD when hooked up on my computer; it sure took a while. I used the standard "Manage" function in Windows Explorer to do the formatting, and split it into two partitions, in the NTFS format. Ever since then I've been absolutely unable to dump/install games in the USB Loader. Even the super-quick Wii Sports will freeze up before reaching the end. It will freeze, then crash with an EXCEPTION DSI screen and a CODE DUMP. Seeing as how it worked on Friday, I'm guessing it's more likely a hardware issue than a software one, but I'm still not 100% certain. Anyway, reformatting this hard drive multiple times in one weekend is crazy, but I didn't know what else to do. I tried using either the first or second partition, trying different sizes, using other programs to format to FAT32 (as opposed to NTFS), or using WBFS Manager to pre-format to the WBFS format rather than let the USB Loader do it. No luck with the dumping. Other than suggesting I buy a new hard drive, if the hard drive is indeed the issue, does anyone have any suggestions?
