Homebrew channel doesn't recognize SD card

So I bought today an SDHC 4GB card and istalled homebrew channel with no problems at all.Then i created an "apps" folder on the SD card and put some apps in it.But when i insert my SD card on Wii,homebrew does nothing at all.Also when i manually try to load the SD card through homebrew i get an "unexpected DSI error" or something like that. I tried the same with my usb drive and although i got the error at first,it seems to be working fine now.

P.S. I already tried formating my SD card like a million times,but still nothing happens.

Each app has to be in its own folder inside the "apps" folder.

Yes I know,i did that.Still homebrew only recognises the usb drive.

If you've already got a USB drive attached, you have to open the options screen and select SD to make it look there.

I did that and either nothing happens or I get the dsi error I told you about.

Today I tried forcing the sd card into the slot and it finally showed the apps.Then I loaded my USB drive,but when I tried to load my sd card again,the same problem happened.

Could it be that the sd card slot is damaged or something?

"forcing the sd card into the slot"; yeah that sounds like a hardware problem.

Well i don't actually force it,I just hold it inside when i hear the "click" sound till it loads the apps.
