I have two seagate hard drives. Each are 500 gbs. I used gparted live to make two partitions on the one hard driver, each 250 gb. I set one to NTFS format and the other to EXT4. I installed Windows 7 on NTFS. Installation went smooth and my storage hard drive still shoed 500 gb's available. Then I installed Ubuntu Desktop 12.04 LTS in the EXT4 partition. I selected the first option where it said that Ubuntu detected another operating system and so will install in the other partition. Everything seemed to go fine. When I booted, grub displayed my two primary boots (the ubuntu and the windows 7 installation in addition to memtest). But something stranged happened. When I booted in both Windows 7 and Ubuntu 12.04, and I looked at my storage drive, it now only showed 250 gb available! What happened to cause my storage drive to be split in half? I didn't touch it at all during the partitioning and installation process. It should remain at 500 gbs.

This is the output of sudo fdisk -l:

UPDATE: How come for the sdb device it shows 4 partitions, HPFS, Extended, Linux, Linux Swap? That drive should be completely empty. I never partitioned it. With gparted, the disc was completely empty.

You will have to be more specific. Either you partitioned both drives, or you aren't looking at the right drive. –  psusi Apr 18 '13 at 3:51

Can you add the output of sudo fdisk -l? –  Mitch Apr 18 '13 at 4:33
    
@Mitch I updated the question with the output. –  JohnMerlino Apr 19 '13 at 0:54

@Lucio does this mean I can boot again from gparted and just wipe out /dev/sdb to make available all 500gp for my storage drive? Why does it currenty have partitions like HPFS, Extended, Linux swap, etc? –  JohnMerlino Apr 19 '13 at 14:02
