If you have space or an extra drive, you can always make a backup image of your Windows install and save that as a backup. If you find that you need Windows again, just recover the Windows backup image and it’ll be just as you left it.

I’m not sure what OP is trying to create, but most Internet-in-a-box projects I’ve heard are trying to recreate text-centric sites offline (Reddit for example). I doubt they are trying to create an offline version of video sites, like YouTube. The size requirements alone make it unlikely.

I don’t know for sure, but I think they generally refer to archives of specific websites that would be good to keep in case of an apocalypse. The thing that comes is the Wikipedia archive that is, at minimum, text-only. Not sure which other website archives people like to keep in case the Internet apocalypse.

Same reason why people prefer getting a new car to a used car: you don’t know the care and maintenance, or wear and tear, the previous owner maintained. You could end up saving money… Or you might end up buying a junker.

If you don’t mind shucking, Best Buy has a sale on WD 18tb extensions for $200 each. Last day is today unless it returns in black Friday.

The Internet is for porn…

I’m really sad about this. I was planning on buying a drive from them, but now their prices don’t make much sense around black Friday.

I’m hoping for Best Buy to put up 18tb external drives up again for $200.
