screwed up a drive (i think)!

Hi.
I have a 640G drive I put back in a laptop, that now is showing up in
the "File System" as a vg_dell45 icon, as well as showing up under the
disk utility as a "Multi-disk Device" The drive didn't appear in these
areas before.
Here's the situation:
-Took the drive out of the laptop
-Inserted the drive into a usb external bay, copied a bunch of files
to a separate system
-Before copying the drive, I ran the "vgchange -ay" cmd to be able to
access the different partitions on the drive and copy the data
-the initial system is an old FC13, the newer system is a Centos6.5
-after copying, I then reinserted the drive back in the initial FC13 system.
-everything boots, appears to run
-however, when I look at the GUI File System/Disk Uility apps, I get
what I mentioned above...
I then did a fdisk -l and I see that the drive no longer appears to
contain valid partition tables!!!
So, something has happened. Researching doesn't point to anything, so
I'm looking for pointers as to the bonehead screwup I did, as well as
how to correct it.
Here's the output of the fdisk -l

here's the df -h for what it's worth..
[root at dell-1 ~]# df -h

So, how can i get this back to normal!
Thanks
