ReadyNas 104 RAID 0 Failure - Can I re-establish RAID 0 between drives?

Updating the firmware in a situation like this is not recommended unless you get professional advice from us that determines that it is.

Using RAID-0 is inherently risky. If a disk fails all RAID-0 volumes using that disk are lost.

Data recovery is much more likely to be successful if a redundant RAID level is used.

What are the SMART stats of your disks like?

Both disks in the array look good. When i do a btrfs check /mnt/md127 thats when I see the bad block. When trying to mount thats when the message in dmesg is generated..
