I know I seem distant and all these days, but this really sounds like a 4K advanced disk problem.
What makes me say this?
The nvme was a 512gb disk, I assume and it’s just a guesstimate. The sata disk is also a 512gb disk, guesstimate.
But look at the layout variances in reported disk size. One shows as about 465GB (sda) while the nvme shows at 477GB (nvme).
The oversized for each partition would seem, too me, to come from calculating disk sectors at a larger size than the actual disk can use.
I very well could be wrong of course and welcome any suggestions.
@sebastian-Roth I think we need to try figuring out a suitable mechanism to upscale to 4K only (less needed as most advanced disks will allow reappropiation of the sectors into 512B) as well as downscale 4K back to 512B. I don’t know of a good approach to do such a thing yet but it seems more and more people are looking to image cross spectrum.
