the device can't read SD card any more after..
Some hours ago, I met someone who sent me a message to buy my DR1000S. And he tried checking the status of the device. But he was a crazy person. While the device is being booted, suddenly he ejected the SD card. After the device is booted, it can't read SD card and displays no file on it. And it can't be booted anymore, just 'No memory card found' screen appears on it.
Is there a solution? I don't know where the problem is and what to do. Please help me if you know something about it.
