Access ReadyNAS HDD via Win11/WSL2?

I used to have a ReadyNAS Ultra with two HDDs in RAID 1. I got rid of the HW a while ago but held on to the HDDs. Content was mostly moved to a cloud service first. Today I tried to access it with a Sata-USB Adapter. I mounted it manually in WSL2, since it is from a Linux system. However, Ubuntu tells me it can not mount it because the Linux_Raid_filesystem is unknown. Anyone have an idea on what I can do? Is there a Netgear tool for this? EDIT: changed Duo to Ultra to avoid future misunderstanding
