• Objective ::  Every block that the Linux kernel can address on the internal SSD must be accounted for by partition table + LUKS + filesystem headers; no “service partitions” may remain mountable.
• Key-result ::  Compare the sum of visible partition sizes with the total physical block count reported by hdparm -I; difference must be ≤ 1 % (allowing for rounding and over-provisioning area).

Test:

#+begin_src_

phys_blocks=$(hdparm -I dev/nvme0n1 | awk '/LBA48 {print $4}')

sum_visible=$(blockdev –getsize64 /dev/nvme0n1p* | awk '{s+=$1} END{print s/512}')

echo $phys_blocks $sum_visible | awk '{printf "%.2f %%\n", 100*($1-$2)/$1}'

#+end_src

Expected output:

≤ 1 %

Tonight’s executable test bash Copy

phys=$(sudo nvme id-ns -H dev/nvme0n1 | awk '/nsze {print \(5}') phys_bytes=\)((phys * 512))

vis_bytes=$(lsblk -b -o SIZE /dev/nvme0n1p* | awk '{s+=$1} END{print s}')

awk -v p=$phys_bytes -v v=$vis_bytes 'BEGIN{printf "%.2f %%\n", 100*(p-v)/p}' Expected stdout ≤ 1 % If the delta is larger, re-check with nvme format -n 1 (destructive) and re-install. Publish the exact command sequence – it is copy-pasteable.
