So here I am with being able to solve the problem.
Following is the procedure:
fdisk /dev/hda
x - Enter to expert mode
f - Fix the partition order.
w - Commit changes.
Modify the /etc/fstab and /boot/grub/menu.lst files accordingly.
I'm done and everything is shown perfect.
Now my questions,
I did all this to solve the occasional hibernation problem that I faced
which I suspected to be because of less swap space (My physical RAM is 768
and my swap was 512).
How many read/write heads does an IDE disk have (Eg a 30GB IDE Disk) ?
Does having multiple swaps on one single disk enhance/degrade the
performance ?
Should I merge the two swaps to one single swap ?
TIA,
rrs
