Can't read former internal hdd file system via usb (fedora volume group name conflict)

Question

I took a hdd out of my fedora 25 laptop to replace with SSD. The old drive is in an enclosure now. I plug it in via USB and it mounts and is identified correctly as a 1TB total capacity drive. However I do not see the file system.

All I do see are - some files with names like config-.fc25.x86_64 - initramfs* files - System.map-* files - vmlinuz-* files - efi folder (empty) - extlinux folder - grub2 folder - lost+found folder

Is there something I can do to try to regain access to the file system?

Sorry if the information is minimal. If more is needed please ask.

Current system is also Fedora 25. thx

So I have a logical volume. Okay to get the name of the volume group

[w@localhost]$ sudo pvs
  PV         VG     Fmt  Attr PSize   PFree
  /dev/sda2  fedora lvm2 a--  231.88g    0 
  /dev/sdb3  fedora lvm2 a--  930.31g    0 

and here is my problem (or at least what I am not sure how to deal with). The VG on my root is named 'fedora' as is the VG on my old hdd. So I am stuck here...

[w@localhost]$ sudo lvdisplay fedora
  Multiple VGs found with the same name: skipping fedora
  Use --select vg_uuid=<uuid> in place of the VG name.

IF the VGs did not have the same name I would get the logical volume names (which are quite likely 'home' and 'root') and mount the 'home' volume.

But how to I specify the fedora/home on my external drive sbd3 and NOT fedora/home on sda2? thx

UPDATE2: The first entry must be the external drive because of the size. But is there any other way to determine that?

[w@localhost]$ sudo vgdisplay
