So, while waiting for imaging to finish I have indeed found several tools for recovery of files from zfs volumes so the big filesystem also, that is being duplicated, could yet also yield the latest version of my wallet.dat Ooof so much time this takes... Disks have grown faster than their access speeds... About 9000 seconds to duplicate 4tb reading from usb-c writing to 3.5gb/s NVMe This r-studio is strangely not finding much of anything on this 1tb 2.5" SSD, which I am sure I put a backup on What a mess omg There is still hope though. Almost certainty of recovering something, just really hope I don't lose any utxos this would really suck
