After a series of unfortunate events, I have a clone of my laptop's hard drive as a .dmg file (created using
dd). The dmg was built using the
noerror option, which means that significant portions of this dmg and NULLed out. (for more information on
dd, see this: http://hints.macworld.com/article.php?story=20050302225659382)
Because the first several megabytes of this dmg file are zeroed out, the dmg refuses to mount. Disk Utility can't repair it, so I'm wondering if there's any way to copy some other disk's boot sector into my dmg so that it will mount.
I realize that this is probably a risky thing to do, but if I can just get 1 folder off of this dmg, it would be worth my time.
