Overriding reported sector size

[martin f krafft]

Dear list,

recent disks >2Tb come with 4k sectors, but they report 512b sectors
to the OS for "backwards-compatibility" â presumably, other OSs
do not differentiate between physical and logical sector size, which
Linux can do and does.

All the block device layers nowadays can auto-align themselves, but
that obviously only works when they know the true sector size.

Rather than fixing each and every tool, and/or telling each and
every tool to ignore the reported sector size and to use 4k instead,
is there a way by which I can "fix" the sector size at the OS-level?

Thanks,
