Hey so i got my hero last week or so and it came with the "old" kernel. I put a 8gb class 2 sandisk card in it and used it for a while, not encountering any problems. THEN i did an update to the official 2.73xxx kernel and since that I've had contiuous problems to access files on the sdcard. This is when i try to play music(it says audio format not supported),view pictures(a little "!" appears instead) and when i download apps from Market(the dl doesnt complete). All this happens sporadically, so sometimes I have the issue, sometimes not but its ANNOYING I'm new to the whole Android thing and I love it so far, except for this. I have searched this forum and havent found an answer so I'm hoping somebody can help me! //So far I've tried rebooting, reseting and I'm testing the sdcard with H2testw //h2testw says the card is OK. help anybody?
