You asked for documentation/proof. You got it. End of discussion.

Here is a recipe for Linux. Download an iso-file (e.g c.iso) and mount it to see the files inside. Now run "shred -z c.iso" as root to zero out the iso file while it is still mounted. Then run "free && sync && echo 3 > /proc/sys/vm/drop_caches && free" to clear caches (unix.stackexchange.com/a/87909/4869). Now look again...

And you do not have to dismount an image to change its content...

Anything is possible if you have physical access to the machine. This is not implied in being root. Please do not comment any more on what funny things are possible if the user with root rights can touch the hardware. Thank you.

I've pointed out how to change an ISO9660 image even if it is supposed to be unchangeable. My point is that if a bit is writable at all, root can write it.

comment With Windows Server 2008, when do I need 32-bit and when do I need 64-bit?
32-bit windows can easily handle more than 4 GB RAM. Each 32-bit process, however, cannot utilize more than 4 GB each.

No need to be sophisticated - just overwrite the image file with zeros.

Root can still delete a file by manipulating the image directly. It is just a normal file which happens to be mounted.

@jpmc26 hence CD-ROM drive. Those are read/only.

comment Fast way to recursively count files in linux
Piping is fast enough. The problem here is that reading from the disk is too slow.
