A FAQ.
>From the Summary:
If you have an old fdisk and it warns about ``overlapping''
partitions: ignore the warnings, or check using cfdisk that really all
is well.
>From the text:
What is this nonsense you get from fdisk about `overlapping'
partitions, when in fact nothing is wrong? Well - there is something
`wrong': if you look at the begin and end fields of such partitions,
as DOS does, they overlap. (And that cannot be corrected, because
these fields cannot store cylinder numbers above 1024 - there will
always be `overlap' as soon as you have more than 1024 cylinders.)
However, if you look at the start and length fields, as Linux does,
and as Windows 95 does in the case of partitions with partition type
c, e or f, then all is well. So, ignore these warnings when cfdisk is
satisfied and you have a Linux-only disk. Be careful when the disk is
shared with DOS. Use the commands cfdisk -Ps /dev/hdx and cfdisk -Pt
/dev/hdx to look at the partition table of /dev/hdx
