A new disk was presented to a server as /dev/ sdd.

The command that can be used to check if a partition table is on a disk is fdisk. The fdisk command can display, create, delete, and modify partitions on a disk. To show the partition table of a disk, the administrator can use fdisk -l /dev/sdd (B). References:
