How to add a new partition to an existing Red HAT 8

[bj]

Hi !

I have a red hat 8.0 & Windows 2000 on a intel box with a 60 GB hard drive .


Only 20 GB has been partitioned into 10 GB of NTFS and 9 GB of Linux , file
id 83 ext 3 and 1 GB of Linux swap , file id 82 . 

I want to use some free unallocated space from the remaining 40 GB for my
linux . 

But I could not get fdisk (from the command prompt ) to show me the
unallocated space  and partition it . 

I could see the unallocated free space when I run KDE hardware browser . 

I could find the GUI disk druid too . 

So How do I partition the unused free space for my red hat 8.0 . 

Which utility do I use ? 

When ever  I use  fdisk , and choose option n ( to add a partition ) , it
gives an error message saying that I need extended partition or I need to
delete old partition to create a new one . 

But I have 40 GB of un used space on my hard drive. 

Please advice . 

Thank you for your help in advance . 

cheers,
bj
