Hard drive only reports as 4GB

I have a laptop hard drive that's a 500GB drive.

When trying to access it though it's only showing 4gb, doesn't show any raw drives, doesn't show unused space, just shows as 44gb. It's a seagate drive and the seagate utility also shows is as only 4gb.

any ideas on ways to get access to the rest of the drive, It's a relatives laptop drive that they want me to pull pictures from but i'm not able to see the actual drive.

I've tried direct connecting it to another machine (ie via the sata cables), and i have a usb to sata converter that i use on my laptop to try to see it. I've tried some disk tools in Hirens boot cd but they all show the same, 4gb partition and only that one.
