Disk space gone after upgrade - Howto see it?

Hi Linux / *nix experts

I have been a Linux user since redhat 4.2 - and have lately upgraded from fedora 14 to 15 - by PreUpgrade command.

All went nice and easy .... but somehome 45G is now GONE from my / partition?

Background:

Before upgrade:

I had

/
/home
swap

And on /media I had the following

/media/photos
/media/videos


After upgrade:

/
/home
swap

But my dirctories
/media/photos
/media/videos

have GONE

But the SPACE is STILL in use - (from du/df commands)

Question:

How to "mount" these dir once more - or alternativly - free up the space (would like to mount the folders once more as photos exist on these I would like to have)

Information:

Total DISK size= 160GB
