Would I need to use the USB tool first and then do what you say in the link you posted?

Ok, thanks. If i cleared my cache how would i then go about re-doing my internal boot setup? At the moment if i use either the onboarding or internal boot wizards it doesnt give me the option to re-configure it since it has already been configured.

Sorry if i’m being a bit of a noob (i am) but currently i have a 500gb NVME that has a 16gb partition used for boot and the remaining space is used as my cache drive, what would i need to be erasing in order to use my new Optane drive in a boot mirror? Also, the onboarding wizard said that 16gb is the minimum required size for a boot partition and while my Optane drive is 16gb its only showing as 14.4gb in Unraid despite being brand new so maybe it wont work no matter what?

Thanks. When I tried to add my 16gb Optane drive it said it was too small, it’s only showing as 14.4gb in Unraid.

It looks to me like it's just going to create a cache pool rather than boot?

I transitioned to internal boot by using my single nvme cache drive as a boot+data partition and I i thought i would add a second drive for a redundancy since intel optane drives are so cheap. I added the Optane drive just now but neither the Onboarding Wizard or the Internal Boot Wizard in Tools gives me the option to add it. Am I stuck with just have a single boot drive or is there a way around this? Thanks

Is the age of a disk not really a concern then as long as it hasn't been used?

I've attached the full zip file of the report but i've no idea what i'm looking for. Also, i've tried to convert the Raw Read Error Rate to Hex as you can see in the screenshot. Since it's only 7 digits does that mean there are no errors? Thanks tower-smart-20240110-1429.zip

It's a Seagate Exos Enterprise. The screenshot i posted was from a short SMART test so im assuming you mean the full test (sorry, i'm still quite new to a lot of this).

I'd never bought a used Drive before but decided to take a punt buying one from CEX (UK store) and grabbed an EXOS Enterprise 6tb for £75. I was disappointed (but not surprised) to find that it was quite old with a DOM of 2018 but I plugged it in to my Unraid NAS anyway and ran a SMART short test and i've attached the results. I'm kind of a noob with this stuff so I dont really know what i'm looking but it says it only has 85 power on hours which is mad and it has a very high RAW_READ_ERROR_RATE and SEEK_ERROR_RATE. Am i right in thinking this drive is completely boned?

I've followed the guide from @craigr but for some reason the transcode isn't taking place on the RAM, as shown in the first screenshot. The movie is definitely being transcoded as you can see below. My Plex docker setup is shown below. I dont know where i've gone wrong and I cant figure out where the transcoding session is because it's not in my Appdata either. If anyone could help me out i'd really appreciate it. Thanks

Memtest has passed without any errors. I think im just going to replace my cache drive since i have a spare nvme drive following a recent upgrade to my gaming pc.

As an update i tried to move a file from the array to the cache and it refused to do it because the file system is read-only which, as I understand it, is down to corruption on the cache drive. Unfortunately, i dont know what I should do about this.

Are you able to help understand what to do about that?
