HDD not mounting

Support
1

Im having trouble mounting my HDD this morning, can anyone help?

It was formatted ext4
sudo mkfs.ext4 -m 0 -T largefile4 -L <drivename> /dev/sda

Its done two plots then encountered some sort of problem. When i try and mount i get this:
(venv) user@chia2:~$ sudo mount /dev/sda /mnt/hdd mount: /mnt/hdd: wrong fs type, bad option, bad superblock on /dev/sda, missing codepage or helper program, or other error.

mount -t ext4 /dev/sda /mnt/hdd Gives me the same error.

fdisk info gives me:
Disk /dev/sda: 931.53 GiB, 1000204886016 bytes, 1953525168 sectors Disk model: d2 quadra Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes

dmesg gives me a fair few of these:
