Below the tray on mine, about 1.5" to 2" from the right hand
edge and just below the tray, you'll see a "paper clip hole".
Straight a stainless steel paper clip, to use as a pusher.
(Some of those hold their shape better.)
Place the end of the unraveled paper clip, into the hole.
Push on what is behind the hole. You should see some
movement of the tray.
Now, on mine, just below the paper clip hole, is a pearl
white plastic cover, which might house an activity LED.
I've never bothered to check whether that's working, as
a "tray cover" hides the drive in normal operation on
my G4.
The PC I'm sitting in front of, has the paper clip
hole in exactly the same relative location.
On some Macs, the trim around the drive tray can
hide the paper clip hole.
There are probably Macs that don't have the paper
clip hole. This is the recommended procedure...
Another trick is the force-eject on boot:
This is done by restarting your Mac and holding down
the mouse button (or trackpad button if you have a laptop)
as the system boots. Hold it down until the system boots,
again the disk should come out.
But maybe that won't work, depending on what other
hardware is missing from the machine. The paper clip
method isn't "a lot of fun", but it is more mechanical
and doesn't rely on tricks.

And remember your project status:
1) You've experienced an I/O error on the drive.
(Whereas my test got Permission Denied.)
While there might be a technical explanation for this
that doesn't involve hard drive damage, we don't
know at this point, what shape the drive is in.
2) You haven't evaluated the SMART stats yet.
(HDTune in Windows. SmartMonTools in Linux.)
Mounting a sick disk on a freshly installed Mac,
might give initial joy in the ability to see the
disk icon. But things could rapidly fall apart if
the OS can't actually read the drive. I don't
recommend either CHKDSK or Disk First Aid on
sick drives, as the outcomes are too varied
to take the risk.
If a drive is sick, you want to make a copy of
it first. Maybe clonezilla would work. I don't know.
But use something. And if it's a 500GB drive, verify
that the "thing" the backup program got is 500GB in
size. Proving that you have a snapshot of *everything*.
If a file handle is lost, the file clusters could
still be there. A "conventional" backup might not
capture the "recoverable" files sitting on the disk.
A "ddrescue" style copy, gets as much as possible.
And ddrescue doesn't care about partition types,
as all it does is hoover up sectors. It has a
very simple job to do.

Loaded Ubuntu 18.04.
I went here to get SmartMonTools for Linux, in particular, for Ubuntu 18.04
Bionic Beaver:
https://packages.ubuntu.com/bionic/smartmontools
I clicked the amd64 file, and it took me to the download page for
smartmontools:
https://packages.ubuntu.com/bionic/a...tools/download
which told me:
If you are running Ubuntu, it is strongly suggested to use a package manager
like aptitude or synaptic to download and install packages, instead of doing
so manually via this website.
aptitude was a red link, so I clicked on it (even though I knew I had it
already because I'd used it in terminal mode sudo apt-get etc...); when I
clicked on that link, it took me to the download page for aptitude:
https://packages.ubuntu.com/bionic/aptitude
I clicked the amd64 file, which took me the download page for aptitude:
https://packages.ubuntu.com/bionic/a...itude/download
which told me:

Dizzying, frustrating, PITA.
OK. I kind of remember the sudo apt-get command, so I launch Terminal.
I figure I'll install both gddrescue and smartmontools.

I press y, and this comes up:

The only way I could close this window was to end the terminal command, so I
did.
I went here to find instructions on how to run SmartMonTools:
https://www.thomas-
krenn.com/en/wiki/Analyzing_a_Faulty_Hard_Disk_using_Smartctl#SMART_ Tests
I opened Terminal, and typed (I was pummelling the thing by now)
smartctl -a /dev/sdf2
(The Disks app in Ubuntu had previously identified the iOS partition 2 as
sdf2; the EFI partition was sdf1; the unallocatd partition was sdf
How do I get SmartMonTools to run while in Ubuntu?
Thanks
SmartMonTools has, as a feature, the ability to email you
if a disk is failing. That's what "PostFix" is for.
Just feed PostFix any old baloney. Hit OK or whatever.
Hit enough keys to finish the PostFix step and continue
with the SmartMonTools.

These are some pictures of dealing with a LiveDVD of Ubuntu 18.04 x64.
Turning on the Universe and Multiverse repositories is the first step.
It even makes File Sharing, further in the pictures, work.
