I tried to message you too and got the same message. It said you have to allow messages from newbies in your mail settings in profile>personal message options : Allow newbies to send you PMs. Ive been on here since 2013 yet somehow I'm still a newbie. Must be related to post count or merit. I dont post all that often.

I was going to recommend a data recovery company if you are in Australia, and have no luck finding the wallet on your drive copy. We recommend this company to all our clients.

As for finding the wallet on the drive copy you have, I would scan the drive with pywallet:  https://github.com/jackjack-jj/pywallet
It's a python script, so you would need to install python2.7 (I assume you have a windows PC) : https://www.python.org/download/releases/2.7/

You would then need to open a command prompt, eg type cmd in the windows search bar. If you're as old as I am you should be fairly comfortable running commands form the command prompt.

You then run it like so:

# --recover option tells pywallet to operate in recovery mode (ie. scan the device looking for wallet files)
# --recov_size options specifies the size of the device... if you have a 256gig drive, or 1024 if you have a 1Tb drive
# --recov_device specifies the drive letter for the device you want to scan
# --recov_outputdir simply tells the script where to place any "recovered" wallet files etc.

For example:

In the above example
Pywallet will scan the entire e: drive (you would use the letter windows assigns the drive when you connect it) looking for the data signature of old bitcoin wallet files, even if they are hidden/deleted, and if found put the results in c:\recovered-wallets folder
