Try checking the state of the SD card before you attempt to write to it. It may be used as a shared drive, corrupted, full, etc. A list of states can be found here: http://developer.android.com/reference/android/os/Environment.html

Here's an example of getting the states:

String state = Environment.getExternalStorageState();
    if (Environment.MEDIA_MOUNTED.equals(state)) {
        mExternalStorageAvailable = mExternalStorageWriteable = true;
    } else if (Environment.MEDIA_MOUNTED_READ_ONLY.equals(state)) {
        mExternalStorageAvailable = true;
        mExternalStorageWriteable = false;
    } else {
        mExternalStorageAvailable = mExternalStorageWriteable = false;
    }
