No Rebuild option in RST - RAID 5 reads as RAID 0 and won't auto rebuild to spare

[evo]

I have a 4 disk RAID 5, and recently, it appears one drive dropped out of the RAID.

I installed a new drive, and it's recognized, but I cannot do anything with it.

RST does not give me any option to rebuild, or repair. I was able to set the new drive 'Mark as spare' but it does nothing else, no auto rebuild, or option for manual rebuild.

I do not have a backup, as I was just about to start one on a new ext hd I bought (funds also would not allow for the longest time)

I specifically set this up as RAID 5 as it offers a great mix of capacity and security, but what's the point if I can't do anything, as is the case now? It may have well been a Striped array.

Although now i'm not even sure it was a RAID 5 tbh...iirc I had about 16TB capacity, on 4 x 5TB drives, so a RAID 0 would seem more likely...

Either way, any one have any ideas as to what is going on? if it were in fact a RAID 5, I should be able to rebuild, no?

If it was actually a RAID 0, am I completely SOL?

here's the system report (attached):

Hello evo

Thank you for posting on the Intel️® communities. 

On the report provided we noticed that this was a RAID 0 instead of a RAID 5:

You can't recover or repair that RAID 0 because of the failed drive but you can create a new RAID 0 (or other) following the steps below:

1. Turn off the computer.
2. Replace the failed hard drive with a new hard drive of equal or greater capacity.
3. Turn on the computer. When prompted during system startup, press Ctrl+I at the same time to enter the option ROM user interface.
4. Click 2. Delete RAID Volume.
5. Use the up or down arrow keys to select the failed RAID 0 volume.
6. Press Delete to delete the volume.
7. Press Y to confirm the deletion.
8. Click 1. Create RAID Volume and follow the prompts to create a RAID 0 volume.
9. Click 6. Exit.

yeah, thanks. i know how to set up a new RAID, but I cannot get into ' option ROM user interface'. doesn't matter though.

looks like i'll just haev to wipe and start over... turns out i forgot i had switched from RAID 5 to RAID 0 when i needed more space and couldn't afford more drives. I knew the risk, and here we are

thanks
