fdisk ide serius problem

[Piaga]

Hi all,

I've got a big problem with my ultra5 disk partitioning
I've got 2 different disks but the problem is the same (maybe me...)
on fdsik I can use only 7Gb of 40gb disk and don't know why!

I've tried with these disks:

IBM IC35L040AVVN07
Maxtor 6E040L07

at the boot I Can read the right message (hda 41100Mb)
this is my fdisk Sun label

I red many kind of posts and did many actions but the problem still remain..
is 40Gb an unlucky size?
Please help me

Really thanx

Does the drive show up in your BIOS as being 40 Gb or 7 Gb? How old is your machine and what architecture is it?

I just got my Ultra5 up and going last weekend. I guessed things right.. but here is some help. After fdisk do the "o" command to do just an empty DOS partition table:

Hi all, thanx so much for the answer.
These are my results:

use sun4u ultra5 with openboot 3.31

fdisk /dev/hda

Command (m for help): o

The number of cylinders for this disk is set to 9156.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

This will happen with both the 40Gb disks
