It wants to say "found no GPT at all and cannot easily convert the MBR
partition table".

NTFS would be a possible candidate for the filesystem inside the
partition. What does this command report:

  file -s /dev/sdm1


But the complaint from gdisk is just about an MBR partitioned stick with
no unclaimed room at the end for storing the GPT backup table.
Indeed if you want to convert the MBR partition table to GPT you will have
to delete or shrink the single partition number 1. (Shrinking would
of course depend on what kind of filesystem is in the partition and
whether Debian has shrink software for it.)
The same will be necessary if you want more than one partition.

Whatever, there is nothing suspicious about the gdisk behavior with that
particular disk.


Have a nice day :)
