Started the scrub last night, logged in this morning and it says 1 day 10 hours remaining? Is that normal?
I’ll try and back up the data and order a WD Red. Can’t afford three so would it be ok to swap the 1TB WD out for a 2TB Disc and then do the others when I can?

Sorry youv’e lost me, whats this going to resolve?
Order the WD Red. Just make sure that specific model is CMR. I think the scrub is having trouble as my 20TB drive takes about that long for a scrub. I would expect your system and a lot smaller size to be quicker. If you have a spare sata connection. You can power down, add the new drive to the computer while keeping your current drives attached. You power up and select the ‘bad’ drive, double check by the serial number to make sure you are replacing the correct drive, and follow the online documents for drive replacement. Keeping all the drives in use can make it a little bit safer to do the replace since you are set up with Raid-Z1.
If you notice errors on your system with the boot-pool or drive, you will have to plan for that too. If you have to stagger purchases, I would just power the system off and not use it until you are ready to replace all failing devices. Not sure if you just have a problem HD or HD and boot-device. Just going by the Alert errors you posted images of.
I think Coolblacks was just stating that holding in the power button to force a shutdown works for them. I wouldn’t worry about it.
I think that would work. Only thing to mention (if I’m not wrong) is that if you replace the faulty 1 TB HDD with a 2 TB HDD, you won’t have more storage capacity as in the old setup, because a raidz1 vdev only has the capacity of the smallest drive involved. that means if you have a pool with a vdev consisting of 2x 1TB HDD’s and 1 x 2 TB HDD you still have a maximum storage capacity of 2 TB in raidz1. If you are going to change the other hdds in the nearer future this will change for the better. And i guess it wont be a problem, considering the little amount of capacity which is used by you at the moment.
I popped to Argos today and picked up a Western Digital Elements 4TB External HDD. Going to copy everything on the Server and all my other devices / old External HDDs laying around.
Next job sort out all the data on the 4TB drive (keep / delete).
Save up and rebuild the NAS, using WD CMR Reds.
To be honest, whilst walking the dog tonight I realised when I bought the Western Digital Greens, many, many years ago, when I first had the inkling to build a FreeNAS box. One died within a year and I could only get a Toshiba locally quickly (In Germany). It was only last year that I resurrected the NAS and bought a SuperMicro Motherboard and RAM etc. So it’s about time the drives got renewed, I was just flogging a dead horse TBH.
You could remove that bad drive from your VDEV and run the pool in a degraded state. Just know that any more drive failures in that pool means a lost pool. It would give you another copy of data while you work with the external drive copy though. Another option is to hit up friends and family up for any spare 1TB or larger hard drives and use that in the mean time as a replacement for the bad HD. I figure a healthy Raid-Z1 with consumer drives is better than nothing.
