Since I have an usb hard drive,is there a way to run most of my apps from the hard drive instead of the sd card. Is there an option to look for both? Thanks.
You can use a usb stick to load homebrew apps from the Homebrew Channel:
(Taken from WiiBrew: Loading From USB):
"Files and folders on your USB storage device must be structured in the same way that they would be structured on an SD card for use with the Homebrew Channel. For example, you must have an "apps" folder on the root of your USB storage device with sub-folders containing an executable, meta.xml, and icon.png for each homebrew application. Any specific homebrew instructions related to file and folder placement on and SD card also apply if you are using a USB storage device instead.
Your USB storage device should be plugged in before loading the homebrew channel, but it is not required. If you do not have it plugged in when the Homebrew Channel is loaded, simply plug it in and then bring up the Homebrew Channel menu, then select the "Reload" option."
Yes you can run them from a usb hard drive, I personally have a 500 gb drive partitioned in ntfs and a partition in wbfs for my image loader.
You just have to set up the directories for your apps in the same way that they would be set up on the sd card. Also if I remember correctly, you can hit the plus button (or maybe its the number 1 button) on the wii mote inside of homebrew channel and get a load option menu, like load from sd card or usb device, stuff like that.
let me know if ya got more questions
