Is My "SuperBlock" Corrupted?
MacBook Pro 17-inch happily running Apple's most recent OS "Maverick" version 10.9 however that Mac had a recent history of superblock problems.
Is there any way I can determine whether my superblock is corrupted?
My Unix knowledge is next to nil, so be gentle. ;-)
I use Apple's "Terminal" utility to type in Unix commands.
Tried to post a "comment" to expert "arnold" but I am a new member of EE so do not yet know how to navigate here.
arnold offered that Unix "fsck" should be used.
I entered a request for info' on how to use fsck by: "man fsck" but the info' was apparently written is a combination of Latin and Greek.
I _think_ that "fsck -b" might be safe to use to force my Mac to use an alternate block of superblock data.
Then again it might blow up my Mac. (again)
"man fsck" mutters something about an automatic reboot when using fsck.
I do not have the foggiest idea how that reboot will affect me if I use fsck -b

There are several reasons I created the dd code:
1) Time Machine will not back up my Windows partition. (Boot Camp)
2) I want an exact mirror image backup of every block, even the "free space".
3) I just feel better with every possible part of the drive backed up.
For example in these sophisticated hacker days, with even our own NSA sticking their big fat noses in our private lives without our permission, I want to make it as difficult as possible for them to act like "Big Brother".
Its about freedom, do you want _me_ running your life? Of course not.
