А чем они отличаются друг от друга? Инструкция есть по пользованию? Или ман русский?
man fdisk и
http://translate.google.ru There are several *fdisk programs around. Each has its problems and strengths. Try them in the order cfdisk, fdisk, sfdisk.
(Indeed, cfdisk is a beautiful program that has strict requirements on the partition tables it accepts, and produces high quality
partition tables. Use it if you can. fdisk is a buggy program that does fuzzy things - usually it happens to produce reasonable
results. Its single advantage is that it has some support for BSD disk labels and other non-DOS partition tables. Avoid it if you
can. sfdisk is for hackers only - the user interface is terrible, but it is more correct than fdisk and more powerful than both
fdisk and cfdisk. Moreover, it can be used noninteractively.)
Но у меня fdisk проблем не создавал.
