Mount disk error (Newbie here)

Hi all,
I apologize if this has been asked and/or answered before. I am new to OMV as well as use of Raspberry PI, I am trying to create a NAS because i'm tired of connecting hard drives to my laptops to move files over to another laptop. I have followed all the steps I can from what I have found, but I am encountering this error when trying to mount the disk.

using Raspberry Pi 3
I had downloaded the latest version of OMV for it last night
I have formatted my 32GB microSD card to FAT32
I am using a 1TB external hard drive with no separate external power source aside from USB connection (formatted in exFAT)
I then inserted the micro SD, connected ethernet, and external then powered up and went through boot and obtained IP address

Next, I added a user and then went to mount the disk, and now this is where I stand

Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C; mount -v --source '/dev/sda1' 2>&1' with exit code '32': mount: unknown filesystem type 'exfat'

I'm not sure really where to go from here.....any help would be greatly appreciated. I am not opposed to starting from scratch either.
Thank you in advance.

Here are the full details of the error

If you have no data on the drive, use the GUI of OMV to
- wipe the drive (this will delete any data on the drive)
- create a new filesystem on the drive
- mount the drive

Thanks for that recommendation. I'll give that a shot.

Did you mount the drive from CLI?
Should be done from the GUI.

Have a look at these Videos:
OMV Setup Videos

I mounted (well attempted to mount) the drive via the GUI but no success. Still waiting for the drive to finish wiping before I attempt your first suggestion. I'll definitely take a look at those videos too.

exfat isn't supported in the OMV web interface. This basically means you can't use it for data.

good to know in future endeavors. for whatever reason the drive ins't letting me format it to FAT32 on my MAC, i'll try dusting off my old windows laptop and see if that works.

Great recipe for all sorts of troubles and even data loss with Raspberries. Check here for 'max_usb_current=1' and 'raspimon'.

Do you have an alternate suggestion over Raspberry Pi being used as an NAS? I even tried using my Netgear router by connecting an external drive to that following the instruction that they have on their site, but even though it recognizes the drive, it's not letting me use it as an NAS for whatever reason.
