Linux Partitions Issues

**wmorrison1967** · June 25th, 2013

Hello,
I am a newbie to linux and need some basic help with fdisk. I have installed Linux and now want to create some virtual drive on my partitioned hard drive. When I try to use fdisk I am getting no more sectors available on the 500 gig hard disk. This should not be the case since deliberately did not allocate all the space.

This is the result of fdisk -l:

Kinda tricky to read but it looks like you've used all your blocks.
You can open gparted which will give you a graphical visual of your partitions and show you any unallocated space you have available.
if you dont have gparted you can install it using this command:
sudo apt-get install gparted

Thanks for the response. Could I remove this partititon

Partition 1 does not end on cylinder boundary.
/dev/sdb2 64 60802 487873536 8e Linux LVM

without causing an issue and then recreate it smaller?
