There is nothing extra, other than some networking info that is not
relevant to this.

this gives:
Disk /dev/sdj: 468 MiB, 490733568 bytes, 958464 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x2935a40d

Device     Boot Start    End Sectors  Size Id Type
/dev/sdj1  *     8192  90111   81920   40M  c W95 FAT32 (LBA)
/dev/sdj2       90112 958463  868352  424M 83 Linux

I should add that this used to work on 17.10, so it's not new untested
hardware.
