I have an external 2TB HDD that i plan on leaving attached to my ubuntu server. I am trying to format it to ext4 but am encounterin issue
My current setup is a 200gb ssd in the server (sdb), 2x2TB HDD's that are Raid0 (sdc,sdd), and the external hdd i'm trying to format (sda)
ubnt@ubnt:~$ sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL
[sudo] password for ubnt:
NAME FSTYPE SIZE MOUNTPOINT LABEL
sda 1.8T
sdb 111.8G
├─sdb1 ext4 976M /boot
├─sdb2 1K
└─sdb5 LVM2_member 110.9G
├─ubnt--vg-root ext4 103.2G /
└─ubnt--vg-swap swap 7.6G [SWAP]
sdc linux_raid_member 1.8T ubnt:0
└─md0 ext4 3.7T /mnt/md0
sdd linux_raid_member 1.8T ubnt:0
└─md0 ext4 3.7T /mnt/md0
When i try to create the ext4 file system on the hdd it gets stuck for ages at "Writing superblock… 730/14905" (always at the same number) and then gives an error:
ubnt@ubnt:~$ sudo mkfs.ext4 -F /dev/sda

I tried sudo smartctl -a /dev/sda
but it gave no errors.
What can i do to make this disc usable?

For some reason this solved it (not entirely sure why now cause i'm sure i had done this. maybe a restart helped it:
That created sda1 under sda, so i followed with
