.\"O In order to write the partition table
.\"O .B cfdisk
.\"O needs something called the `geometry' of the disk: the number

.\"O The DOS 6.x FORMAT command looks for some information in the first

.\"O FORMAT expects DOS FDISK to clear the first 512 bytes of the data area

.\"O The bottom line is that if you use cfdisk or fdisk to change the size of a
.\"O DOS partition table entry, then you must also use
.\"O .B dd
.\"O to zero the first 512 bytes of that partition before using DOS FORMAT to
.\"O format the partition.  For example, if you were using cfdisk to make a DOS
.\"O partition table entry for /dev/hda1, then (after exiting fdisk or cfdisk
.\"O and rebooting Linux so that the partition table information is valid) you
.\"O would use the command "dd if=/dev/zero of=/dev/hda1 bs=512 count=1" to zero
