HDD size not recongnized

I recently upgraded Hard Disk in my Acer TravelMate2300 -- WD2500BEVE. fdisk only shows 137 GB of 250 GB.
Then I installed CentOS-5 on my laptop and here fdisk shows the full 250 GB.
How can I use the full capacity in Arch Linux

Thanks

Re: HDD size not recongnized

How old is your PC? That sounds a lot like a bios limitation of some kind and centos may be doing some kind of drive overlay to allow you to see the full capacity of your drive .... I may be wrong though. No idea of how to overcome that with arch but I'm curious to see the solution

Re: HDD size not recongnized

Is there another partition that's formatted to some experimental file system?

Try using a gparted live CD to see if the entire HDD is recognized.

I Used gparted live. It showed all of my HDD space and I created a partition there also (of 200GB). But how to manage the created partition from within arch Linux.
From within arch Linux I deleted the patition to create partitions of smaller size, eg., 40GB, and now I am getting error "Unable to seek on /dev/sda" when using fdisk.
Is there any way to Manipulate and use entire space from within Arch Linux.
Why Arch Linux is not recognizing the HDD Size. Even not gparted within arch linux

Re: HDD size not recongnized

My HDD layout was as follows before:
sda1-4.7GB
sda2-11.3GB
sda3-9.8GB
sda4(extended)-remaing of 137GB
sda5(swap),sda6,sda7...

From GParted Live I resized extended and created
sda4(extended)-remaining on 250GB
sda5(swap)
sda6-appx. 200GB
When booted arch Linux fdisk showed the partition of 200GB (appx) and in pcmanfm i am able to use this patition, but I am not sure that I can use full capacity.

Again from GParted Live I changed partition structure
sda4(extended)-remaining on 250GB
sda5(swap)
sda6,sda7,sda8.. (of 40GB appx. each)
Now when I booted Arch Linux fdisk gives error Unable to seek on /dev/sda and pcmanfm only show sda6,sda7,sda8

Finally I am not able to use 100GB of space of My HardDisk

Re: HDD size not recongnized

The CentOS-5 is using util-linux package and ArchLinux util-linux-ng. Is this the problem???
