The physical disks go into the house's nuclear shelter which is mandatory in Switzerland and which is fire proof, and, off course, NRBC proof, the advantage being that it is only a few steps away.
I'm using OneDrive for storage in the cloud. You can get 5TB of cloud storage with Microsoft Office365 Home for 100$/year, with 1 user name per TB though.
When you are building a house, you have two options: have your own nuclear shelter or pay a tax contribution for the collective shelter of your village; actually, Switzerland has over 10 million shelter places or 25% excess over the actual population. A few years ago there was some initiative to stop this (peace dividend and other bullshit); the Fukushima disaster made a definitive halt to this initiative; so we are still building (expensive) shelters.
Strange. The Disk Management module of computer Management will happily remove partitions of any disk, be it created by Windows, Mac, or Linux. I have done that numerous times so know it'll work. Besides, it has a graphical UI too if the command line is an obstacle.
