Can't access NAS - password fail - and not showing up on TV

Geez, you’d think by now I’d know to write long replies in word in case I lose them, but no… After over 15 years on forums, alas, I still get caught, so, after the big long reply I wrote – and lost - here’s a shortened version.. Grrr…

Firstly, thanks, again, Stephen, for your help.

The firmware is version 4.2.24… Probably about 5 updates behind, lol.

There’s nothing on the security ‘page’ – when I click on ‘security’ in the left menu, nothing happens, but there are two sections under the drop down – “Admin Password” and “User&Group Accounts”. Nothing under the Admin Password that seems to fit the question, and under the User Accounts it says “User accounts not found”.

With regard to RAID… I think I have a basic understanding of how it works (although my understanding may be VERY basic! Lol)

I *think* what I want is Raid-0 but I wanted to check whether I was right, and, how I change things if I am…

Currently it says:
Configuration: RAID Level X-RAID2, 2 disks
Status: Redundant

I currently have two 2.5Tb drives in the NAS, and I (obviously) want to add more lately…

I don’t need redundancy or mirroring because I have alternate backup facility, I simply want to use the NAS as a server for TV and movies.

I think it is RAID-0 I need because I want it to all show up as one drive on my windows explorer.

I am, however, wondering whether I should have them as JBOD because I’m concerned that, as I understand it, if they are RAID-0 and one of the drives drops dead, they are all unusable.

So – I currently have 5Tb in there, the next step is to add two more 3Tb, then next year, when I can afford it, another two 3Tb drives. This way, in the end, I’ll have 17Tb in there. That should be enough to keep me out of mischief for a while… (Incidentally, I can’t remember who, but, someone told me it’s best to add the drives in pairs, is that correct???)

Anyway, so, thanks again for your advice, I hope all of the above makes sense.
