Have you already tried connecting to the Mac that was able to mount it?
Yes, and nothing, doing a fsck there are issues with the superblock.
Maybe restarting the Mac while usb plugged might fix it.

If you are only cloning the drive, it doesn't need to be mounted.

I'm wanting to clone the drive, but only used space. It's a 1TB drive, and I really don't want to record blank space.

DD does not need the drive mounted. But what keeps it from mounting might stop DD, too.

Yes, you can
It will copy the hard drive sector by sector so it will record the blank space

Sure, you can bring Dunkin Donuts to any type of drive you like. Don't forget the coffee...

Yeah I assumed this, but figured it might be worth a try.

Scott Moulton from myhardrivedied.com has a lot of awesome free hard drive recovery videos. I think some of the free software he recommends are mhdd, Victoria, and ftk imager. Do a quick search on YouTube.

I'm curious if I can copy the drive contents before I dig further into this, even though the drive doesn't mount.
Checked PartedMagic and the tools that comes with it.
like others said you mount file system, however if you want to do sector by sector copy that does not involve file system layer. think clonezilla and its options to dumb clone (sector by sector )or smart clone (detecting file system and only copy used space.)Forensics do this prior to have an original copy of the victim machine.
