I have a Western Digital HD with about a 300GB partition for WFBS. I had recently taken off a game from my HD and put it onto my computer using WFBS manager. When I put it back on my HD I noticed that it shrank in size considerably. So I decided to do this to all the games that were over 7 GBs to create some free space on the partition. Most of the games worked after I put them back on but there were a few that didn't. Some of the games on WiiFlow I would either get a black screen on loading and it would freeze or simply just going to the coverart would freeze the wii up and I would have to hard reset by holding down the power button. On USB LoaderGX when I clicked the games that would not work nothing would happen and then the rest of the program would be unresponsive. There were a few other games on my HD that I didnt even touch which also didnt work suddenly, SSBB, MarioKart, Metroid: M. I just ended up deleteling them for the time being as I will get them again later. But can anyone tell me why this would happen? Or is there a better/more appropriate way I should be shrinking the ISO files? Other than me taking them off my HD then putting them back on, as its kind of a pain. Thanks to all with any helpful responses. edit: I just read a topic about "Wii backup Manager", is this a more stable/better/widely used program than WFBS manager? Can it shrink ISOs without taking them off the HD?
