Data recovery

So, one of the hard drives in my janky RAID died last weekend and I have been putting off dismantling the array and running as separate drives in the hope that I might be able to insert a new drive and recover the array.

That is a dim hope to me, because my RAID set up was all software, with 6 3TB drives striped in disk management and mirrored in storage spaces (or the other way around, I'm not sure) into a RAID 10.

I figured I would post here and see if any geniuses out here thought any of that data might be recoverable and if I should bother trying, or if I should just go ahead and dismantle the RAID and run as separate drives now.

Note that as of right now, 5 of the drives are still reading as 3TB drives in BIOS, and one of them is only reading as 4MB. I believe the motor may have died. Regardless, none of these drives are currently appearing in disk management or storage spaces.
