I understand the confusion, but printing "MBR" when an MBR header is presen= t is a broadly reasonable interpretation of a FAT filesystem header by a tool looking for MBR or GPT partitions. I'd suggest not putting filesystems on unpartitioned disks, or just not invoking gpart on unpartitioned disks. file(1) is contrib code, there's some upstream a bug can be reported at. --=20 You are receiving this mail because: You are the assignee for the bug.=
