Please help. About 4 weeks ago I bought myself the Moto Droid and my wife the Droid Eris by HTC. The phones are INCREDIBLE and I am extremely happy how stable and user friendly they are. The only problem we are having is every 30 minutes or so, my wife's ERIS tells he that the SD card is unavailable and it is needed to access lost of info, photos, apps, ring-tones, etc.... All I have to do is take the card out (which is in perfectly every-time) and replace it and the phone recognized the SD card once again. But after about every 30 minutes of use the error message appears again. Please help!!!!
