I just got a My Book World 500 and now I wanna isntall some software on it and modify it for my purposes.
Before I go ahead I've got a few questions that may make the whole process a lot easier and faster for me.
First of all, I don't have enough money to risk that something happens that destroys my My Book. So before I do too many things with it, I would like to make sure that it will not be destroyed. The first thing that springs to mind is burning an image of the root partition on DVD. Would that work? I would just do something like:
dd if=/dev/sda1 of=some_file_on_another_partition
Is sda1 the partition I need? Are there other important ones? Is it reasonable to make an image of a mounted partition?
Has anyone ever tried something like this, and, more importantly, tried to revive a My Book this way. I guess it would be necessary to extract the hard disk and connect it directly to a computer to put the image back where it belongs.. but that's ok.
Has anyone ever taken a close look at the MBR? Maybe it would be helpful to know what happens at boot time… and I guess I'd also make a backup of the first 512 bytes of /dev/sda.. just to be sure in case I mess up real bad.
Another thing… when I have taken all safety measures and are absolutely sure that nothing will happen to hurt my Book, I would like to accelerate the compilation process. Isn't it possible to mount the root partition on another computer somehow over network? Well I'm pretty sure there is some way, and then it should be possible to do a chroot into the root directory. That way I could compile and install all the programs using a CPU a little faster than that in My Book. Anyone ever try this? Any opinions on that?
And isn't there maybe a possibility to create another small root partition on the disk with another Linux system without destroying or overwriting the original one, and then just change a few bits in the MBR and make it boot into the new partition? That way I could do all I want without worrying about destroying anything… and most importantly I would have a system that I got completely under control including the Kernel and Hardware and everything…
