I am a medium-experienced Power User with knowledge about most of the stuff (studying this since two years) and I know something about how Linux and Windows work; I have screwed up countless installations and stuff like that (dont want to bore you, just want to tell, that I know what I am talking about).
To the point: A friend of mine has a MacBook, running OS X Lion and a hard drive with about 320 GB (not encrypted, at least not the part that is important) and he tells me that forcing a change of his password would automatically activate a self-destruction (complete wipe of the drive). This could be true and would be no prevention, since I don't want to change the password, I just want to get the files from his drive. So I can simply boot Linux from CD/USB and mount his drive, copy everything unencrypted, and done.
That's what I told him, his answer: "Well, that could work, but my Mac will automatically detect this and wipe the drive before anything gets copied." The main question: Is this bullshit?
From what i would expect, this would work like: BIOS --> Linux --> Mount Disc --> Copy --> Start OS X --> Detect and wipe
So files should be there without the wipe, but he said it won't work, and OS X would be booted before Linux? I was really surprised, so I want to ask you guys.
He told me that he will give me his MacBook and I can try to get his files, but I don't want his disc to be wiped, so I ask here: is it safe to try it out?
