Many thanks for that link

That article is difficult to digest (at least for me) as there is so many information about how the firmware bios and os deal with disks since the old dos systems.

However, if i understood well, modern linux and windows systems don't use CHS (cylinder,head, sector) adressing anymore. They rely on LBA (linear block addressing) that is handled by the bios and the disk drivers.

So, if i am wright, the reported sfdisk warnings may be safely ignored.

Maybe sfdisk should be updated to check if the OS is a modern one and omit the "warning" word from the report.
