This answer is wrong in every important aspect: The cylinder field is only 10 bits wide in the MBR, so fdisk can't help but truncate the cylinder field. NetBSD or OpenBSD fdisk are no better than ours. George Cox is working on "libwhisk" which will supposedly take care of fdisk, disklabel, libdisk and sysinstall once done. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
