Remove External Hard Drive partition, keep files?

[Sickkage]

Hey, is there any way to remove a partition on my external hard drive without completely wiping all my films on the other partition?

It is currently partitioned in two.

The partition I want to remove is MS-DOT (FAT) and the partition I want to keep is Mac OS Extended (Journaled).

In Disk Utility when I've tried to remove the partition the minus sign is greyed out and it says

To erase and partition the selected disk, chose a scheme from the Volume Scheme pop-up menu, set options for each volume, and click Apply.

You can't resize the partitions on this disk.

This partition can not be modified.
Size: 300.34 GB

I'd appreciated any help. Thank you.

You're going to have to erase the disk. Back everything up.
