I got the following working;
Have Black with 4.3U when i started this
Did the IJ exploit to get the HB channel loaded
cfg usb loader 66
USB EXT hard disk - NTFS.
(probably forgetting something here)
Any how got it working and was able to copy my Sports Resort (SR) DVD to the HD.
Launched it from the HD and it went ok, happened to pick Frisbee Golf.
Was 3 throws into it and the system froze.
Power Cycled the WII, came up ok, then went back into SR on Ext-HD.
Basically same thing, a few throws and the system froze.
The HD i am using is an old 150GB drive. Did a thorough format on it before using and finished w/o errors.
Am considering it could be the drive or EXT-USB chassis.
As well not ruling out i did something incorrect in setup of all the prior installs.
Was wondering if anyone else has run across this and resolved.
Have loaded Rock Band 3 on the Ext-HD and is working with no problem, just seems to be SR
