Hello! Some of you have tried to Ext4? is that I have the same problem, but as I have a mac computer, which format is not equivalent to Ext4 to format my SD. I mean, when I use the formatting tool (Disk Utility) gives me the following: FAT32, NTFS, Mac Journaled / without registration, Mac Plus. Therefore do not know if any of these formats is equivalent to Ext4! Thanks for your answers. regards
