In the US, please reach out to my colleagues at NVIDIA DGX Spark Support . This is a likely RMA candidate . DM me if you run into issues with the RMA. Do not share your email or case number publicly on forum.
We are based in the Netherlands. And we are seeing the similar issue where each time we power the DGX spark it goes to BIOS. NVME drive is shown in the NVME configuration (under Advanced tab). But when we boot using a recovering drive, the NVME drive fails to mount.
Really curious to know if there is any suggestion from anyone how to solve it?
