Sprint HTC Hero :: Phone Not Register SD Card At All

So, I was having problems with my Hero not playing videos that were on the sd card, also having problems playing videos on the youtube app. So, I did a nand restore. I also did the restore because my phone was being laggy after installing the DB-OC kernel to speed up the phone. So, I nand restored back to before I flashed the kernel. So it is now running Aloysius 2.1 LWP non-OC. But, now all of a sudden my phone wont register my SD Card, at all. I run Dark Tremor app2sd, and can use some of my apps, while others just force close, or hang. I shut my phone off, and put in a different SD Card, to see if the phone was not registering it, instead of it being the card itself. The phone didn't register the other card.

So, I put in my original sd card after turning the phone off again, and it still isn't registering, and is force closing many apps. Does anyone know what to do in order to fix this? I have no idea why it even started having this problem registering the sd card, as it was reading it just fine earlier. I would do a complete wipe of the phone, and sd card, but am not sure if that will make the phone register the sd card again. When I put my sd card into my laptop, the laptop read it just fine. Please, someone, help me fix this problem! Should I wipe the phone, and sd card, and repartition the card? Or should I boot into recovery and select "wipe data/factory reset"+"wipe dalvik-cache"+"wipe SD:ext partition"?
