Thank you for your offer @473x31, but it appeared there was a problem drive itself, so I sent it back and now have a new one. It’s the same model and size. Before it crashed, I thought it might have something to do with the Monero node app which has recently become available on the UmrbelOS App Store, which was causing it to crash and overheat despite the cooling system I had installed. I’m only suspicious of this app because before I installed it, there was no issue with overheating or crashing, besides UmbrelOS itself being unstable.
Having received the replacement drive, I am now trying again with the Monero Node App, but this time there’s no crashing or overheating, so I’m not sure. I’ve been running a node since 2017 and using Umbrel since mid-2021, and haven’t experienced any issues this catastrophic.
