@elpgkprodqc Le systeme de fichier FAT32 est limité a 2TiO , il me semble.

@voljega thanks for 4TB follow up... I'm going to get one and follow your advice on NTFS usage.
Having the Pi provide the power to 4TB MyPassport is good news as well..

cheers!

it is not directly a size issue. it is not related to the mbr. it is a timeout issue. if the disk is not recognized fast enough i switch to the sdcard. then the disk is recognize (too late) and visible in es. i could increase the timeout or make an option for it.
