Comment (by pulkomandy):
In Haiku we have a simple policy: "don't hide the bugs, fix them". Here,
the bug is in BlockSize, so ze need to fix BlockSize. We should not try to
avoid using it because it doesn't work.
> AFAIK you need UEFI to boot from 4k disk, but that's not really
important here. Besides, you could still use it as a secondary disk
(assuming that there is no hardcoded sector size anywhere in the OS).
Anyway, what I want to say is that what we do with disks with 4kB logical
sectors is irrelevant in this discussion. However, when the kernel block
device layer and its drivers expose such disk to the rest of the world
(including MBR code) then it should be handled appropriately.
Yes, it is a separate issue and first of all the problems with BlockSize
and the missing offset check should be fixed. For the problem of 4K
sectors we should make sure we support them in the whole stack, and also
that our MBR is interoperable with other systems handling it (it seems
Windows won't: systems up to Windows 7 only support disks less than 2TB in
size, and Windows 8 needs EFI and does not use MBRs anymore - but Linux
may support this in one way or another). I opened a separate ticket for
this: #11796
