Depends on how you're virtualizing it and what sort of "hardware-harming" data you're talking about... I can't really think of any data that might harm your hardware to be honest.

Maybe something that overwrites/modifies the BIOS?

Not sure if there is still software out there that does that, but I've had it happen to me once years back.

 

Can it hurt your host OS?

I've been using VM's to test software I don't trust for 4+ years now, if you set it up correctly making sure there is no path that a potentially malicious program can follow you'll be fine.

Obviously don't login on email/Steam/etc in that VM; keep it as close to clean as possible. Making a snapshot right after all updates completed and the install is done makes this process of reinstalling the VM everytime you borked it up a lot easier.

Let´s say i have a virtual OS... would i be able to test potentally hardware-harming data on the virtulized OS without hurting my main PC?

Hardware harming or OS harming? If you create a fully virtualized instance then something that harms hardware would theoretically be stopped as the "hardware" would be simulated for the VM.

 

If you mean OS then yes. It's actually advised if you HAVE to download no so trustworthy things from not so trustworthy sites that you do it in a VM. So long as you don't give it a path out to your local machine light if you bridged the network adapter to your local network.

Yes.  But to be extra safe I'd put the OS's virtual drive on a separate physical disk.  A thumb drive would work if you can handle some slower speed.

Sauron'stm Product Scores:

Spoiler

Just a list of my personal scores for some products, in no particular order, with brief comments. I just got the idea to do them so they aren't many for now :)

Don't take these as complete reviews or final truths - they are just my personal impressions on products I may or may not have used, summed up in a couple of sentences and a rough score. All scores take into account the unit's price and time of release, heavily so, therefore don't expect absolute performance to be reflected here.

 

-Lenovo Thinkpad X220 - [8/10]

Spoiler

A durable and reliable machine that is relatively lightweight, has all the hardware it needs to never feel sluggish and has a great IPS matte screen. Downsides are mostly due to its age, most notably the screen resolution of 1366x768 and usb 2.0 ports.

 

-Apple Macbook (2015) - [Garbage -/10]

Spoiler

From my perspective, this product has no redeeming factors given its price and the competition. It is underpowered, overpriced, impractical due to its single port and is made redundant even by Apple's own iPad pro line.

 

-OnePlus X - [7/10]

Spoiler

A good phone for the price. It does everything I (and most people) need without being sluggish and has no particularly bad flaws. The lack of recent software updates and relatively barebones feature kit (most notably the lack of 5GHz wifi, biometric sensors and backlight for the capacitive buttons) prevent it from being exceptional.

 

-Microsoft Surface Book 2 - [Garbage - -/10]

Spoiler

Overpriced and rushed, offers nothing notable compared to the competition, doesn't come with an adequate charger despite the premium price. Worse than the Macbook for not even offering the small plus sides of having macOS. Buy a Razer Blade if you want high performance in a (relatively) light package.

 

-Intel Core i7 2600/k - [9/10]

Spoiler

Quite possibly Intel's best product launch ever. It had all the bleeding edge features of the time, it came with a very significant performance improvement over its predecessor and it had a soldered heatspreader, allowing for efficient cooling and great overclocking. Even the "locked" version could be overclocked through the multiplier within (quite reasonable) limits.

 

-Apple iPad Pro - [5/10]

Spoiler

A pretty good product, sunk by its price (plus the extra cost of the physical keyboard and the pencil). Buy it if you don't mind the Apple tax and are looking for a very light office machine with an excellent digitizer. Particularly good for rich students. Bad for cheap tinkerers like myself.

*hardware-harming* as in virus to slow the PC down and how do i set it up properly?

That's pretty hard to do with a malware unless there's a massive vulnerability in the operating system AND the malware knows exactly what motherboard you have. I haven't heard of anything like that recently. Regardless, it shouldn't get through a "classic" vm; it might be able to do something if you're using KVM or some other kernel based virtualization, but again, that would require a pretty big flaw in the hypervisor.

It depends, wanacry for example could spread on your network even if you ran it in a vm. I would recommend blocking your vm's network connection if you use it as a sandbox for iffy executables...

What I thought, did some googling as well since it peaked my curiosity and I want to keep my Maximus VII Hero around for a few more years; recently there doesn't seem to be widespread flaws like that. Whew

Never a bad idea, good call.
