So you're trying to mount /dev/sdd1.

The system assigns /dev/sdo1 to the USB partition.

The system assigns /dev/sdp1 this time.

To always mount that device to the same mount point it's best to do it 
by UUID. Find out the UUID of the USB partition by plugging it in and 
then running

sudo blkid

Pick the USB partition from that list (compare with dmesg output if 
needed) and replace the "/dev/sdd1" in you fstab with "UUID=..." (fill 
in the UUID you found).
