Considering that the disc is basically just the digital PSN package on a disc it doesn't surprise me the dumping is easy. I don't think dumping is gonna lead us to a useful hack. Frankly I don't think Sony is going to put much time into the discs and is concentrating on the console hardware/software.
As we all know from the XBOX 360 the disc drive is basically the weakest link in the chain usually. Besides only the pirates care about playing free games. The real enthusiasts are here for running their own code and homebrew.
"PC's BDR can read and dump PS4 discs". So what? Same thing happened to ps3 - we had an ability to dump ps3 isos nearly from the launch day. And what did it lead to? Nothing. These isos were unplayable (were encrypted) and the ps3 scene went to the completely other direction.
I'm not being sceptical, but please, keep your hopes straight. There's no use of dumping bdrs of ps4 as long as they encrypted - finding private key can take thousand years.
The result is a few gigs "*.imgc" file (compressed, gzipped maybe?), compatible with r-image. I am not sure you can decompress with 7zip but you can with "HDD Raw Copy Tool".
You can then convert the resulting img file (500GB then) into a variable size vdi with the following command if virtualbox is installed: "C:\Program Files\Oracle\VirtualBox\VBoxManage" convertfromraw -format image.img image.vdi -variant Standard
It would be best to use a format that is usable in virtual machines (virtualbox, VMware Player, ESX) that is compressed/dynamic so you do not need 500gb free, so a dynamic vdi file make sense. I will try to see what happens when you run a x86-64 vm with 8gb ram with the given disk image as the Playstation OS (Orbit) is based on FreeBSD 9.0. Anybody know how to share few gigs file here ?
