I had updated my Wii to v4.0 (the official way) recently, though I had the Homebrew Channel installed before that. I didn't play with custom IOSes or WAD files prior to the update, so I thought I was hooped as it is often said that I should have before updating to 4.0 to keep that functionality. Luckily, this somehow worked for me: http://www.yafaze.com/forums/viewtopic.php?f=46&t=70 Then, as you can guess from the topic title, I managed to get install the cIOS and get Waninkoko's USB Loader running (v1.5, IIRC...I'm away from my Wii at the moment), and I'm using a 1 TB WD external hard drive ("My Book") that I bought today. I had another loader earlier, but it said something about a "memory alloc" error, but I remembered reading about Waninkoko's being able to handle more than 512 GB so I switched to his. But now I seem to have read that perhaps a 1 TB hard drive is not the best... I backed up most of my games, though a couple got stuck partway through and I had to power down and then start them over...hope that didn't cause any problems... A few games like Wii Fit and Link's Crossbow Training seem to work fine, but most of the bigger games, when run from the hard drive, will crash or freeze in seconds or at least within a minute. Is this a problem with the loader, or the hard drive itself? Is it too big, as it sounds like it might be? Is it a problem with the installing/dumping to the drive or the playing of the disc imagefiles from the drive? Are there any expected software fixes for this, or am I going to have to get a smaller hard drive? Many thanks for any help.
