Disc Images Disappearing......HHEEELLLLPPP!!!

So here is the deal. I have used 3 different loaders and had this issue. My loaders were Uloader, Configurable USB, and USB Loader GX (not at the same time). They all work great for a week or even a month, and then, for no apparent reason, ALL of my disc images disappear!!!! O turn it on and-BAM- all question marks....it's very frustrating! I tried formatting my SD card and reloading it....no luck, same problem....WHAT CAN I DO??

Also, I used this guide to mod my wii, and it says something about installing Hermes for use of my drums....any idea where there might be a guide for this? Why doesn't games like wii sports resort and Smash bro work?

how do I detect other hardware/firmware issues...and how would I fix these? I started from scratch (restored my wii to factory default) and fallowed the steps on the above tutorial. I have tried 2 different SD cards with the same problem.
