Try another SD card and card reader and if you still have issues, send it back. The only way you would normally get that sort of pattern is from high levels of radio frequency interference. This can come about because of a poor contact in the camera or poorly applied shielding or a very old mobile phone or you live next door to a sub-station!
Is it just the one shot or all of them?
