Well, I downloaded Power2Go and installed into a virtual machine so that I can see how they create clones and if it were possible to navigate the disk and what not, but to my dismay I have found that this program is one - giant - heap!
I'll try to be concise and explain. Nope! Impossible for this mind to be concise. TL;DR, I couldn't get the program to function without a lot of dedicated time because its coded in a convoluted manner.
Right away I knew this wasn't going to go very well since they use a downloader stub instead of just listing links to downloads. A downloader stub
can do its own thing. So, when you execute the downloader stub you may have little control on what is installed behind your back. Well, that was exactly the case here. Not only did the downloader stub install the Power2Go optical media component feature set, but some other products I didn't ask for. Which now means that download took longer than was necessary and the uninstall process is lengther due to the extra fluff that got installed behind my back.
Then the biggest issue was that when I wanted to make a backup to a USB drive for testing, Power2Go wanted me to install some kind of dependency Windows development/deployment kit. Well, not only was that over 1 GB in size, but in ISO format that you mount in the virtual DVD drive that Power2Go or other software can create. You can also burn the ISO to optical media or flash media. Giant pain if you ask me. Especially since I thought this would just be a simple setup file you run and install. But to make things as simple as possible I mounted the ISO in the Power2Go virtual optical drive provided by the software. Then its setup file in the mounted ISO executed and this is where my computer got a mouth full. This so-called Windows deployment/development backup kit what ever is a GIANT multi step process which would probably take me over an hour to accomplish. Never mind the fact that when you have to depend on a dependency of any kind and how over bloated this all is, the potential for errors and problems is exponentially higher. I could probably prove it statistically! You know how you have to install a dependency of some type like a .Net version? Well, it's probably because the coder of the software would rather use that dependency (and future dependencies with future software updates since they now rely on it) rather than use pure code without dependencies. Probably offers quicker program functionality without all the dedicated coding time in absence of .Net. And then how many times do you end up getting a stupid .Net issue or what ever? Plus, (and this really ticks me off) .Net is a vector for malware or a hack if you don't use updates. Those
precious Windows updates from the patch Tuesday God that lots of people think they need. I actually have but four for software and hardware needs and have never been hacked or magically acquired malware, but that's a whole different story in of its self. LOL You can call me unorthodoxed I guess.
Okay, so right away I can tell you this software is MASSIVELY over bloated and codded stupidly when I just use a small, free program for clones that weighs maybe around 2 to 3 MBs if that and creates an EXACT 1:1 clone to another drive or in an IMG format. It's called HDDRawCopy and it's portable. Meaning no installation required. Which means I can fire it up in a Hirens live CD environment in Ventoy on a USB stick LOL! /dork mode off
Anyway, it's not your fault or anything. It just ticks me off at how convoluted this was going to be and that I wanted to help try to get your data. But NOPE!
Murphy and his damn laws. Murphy needs to be put on trial!
In frustration I immediately uninstalled Power2Go with RevoUninstaler and in the process failed to see if you could do something with those disks in the program to somehow write the data to a USB stick or an external HDD or something. You are afforded a free 30 day trial of the software so perhaps if you already have this software installed you could check. I'd do it in that virtual machine though. In Windows 7 the Power2Go software conveniently added an unwanted Windows gadget I couldn't get rid of and was focused more on figuring out its backup process rather that futz around with getting a gadget off the desktop. Oh, I could do it, but it's for power users and not for others who know absolutely nothing about computers. The other thing here is that they demand you create an account. Probably for marketing more crap and analytics and God knows what else. I used a temp email address...
So it appears your son-in-law had more patience than I did! Granted it looks like he may have used a Power2Go version from around 2011. So who knows how that version was coded. May not have been this convoluted as this version is.
Again, the other massive wrench in the gears could potentially be if this backup is encrypted. Power2Go likes to call it "military grade encryption." While AES256 is allowed for classified data up to top secret, its deployment has to be done in such and such way with modules and other crap according to NSA or NIST standards. Lets just put it this way. LOL
Yeah, see if you can get some guidance and help from the Power2Go company. I do have my doubts though based on how they code the software, and how they market. I've been interested in how companies of all types market things for years and years and I can see it's used to the nth degree on their website in so many ways. Even the images and what not. I kinda appreciate (not really) how Internet software companies show their downloaded product in a box like yesteryear when you'd go to a store and buy the software in its glorious box. Now I bet those old software boxes from Norton et al go for some money on eBay. LOL!
