Some customers have reported compatibility issues with Japanese SD cards from Sony/Toshiba/Panasonic causing frequent crashes. The factory identified the issue: Some Japanese SD cards draw more current than Apple's limit. The card reader uses the current provided by Apple during reading. If it exceeds 100mA, Apple's automatic protection mechanism kicks in and disconnects it. Some Japanese SD cards draw up to 120mA, while typical cards only draw 90mA.
