Are you saying that fdisk ignores the 4k physical sectors (that you set up in patch 5/5) in favour of the geometry exposed here? That doesn't make sense to me, since it would misalign 4k-physical ATA drives if it did. I don't see anywhere else in the kernel reporting (1,1,1). The most common form to fake a geometry uses (64, 32, x), including SCSI. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
