How can I possibly try to out-do the great diary Rob posted?  I can't so I'm not even going to try.

Instead, and because it's been sl .. err, qu ... err ... not particularly eventful, not that we're superstitious or anything, here is a quick forensic challenge for everyone.

The first person to correctly identify this and tell me the three things that are wrong will win fame, fortune, the undying admiration of everyone who visits us and, best of all .. a ISC sticker!  ;)

UPDATE:

Surprisingly, we don't yet have a winner.

It is the first sector of a drive so the item have been identified properly, and AA 55h is indeed missing from the end of the sector, so two problems remain to be found.

Yes, you could just load it into EnCase or something similar and have it spit out results to you, but what fun would that be?  :)

Hint: I know it says NTFS when you convert the hex to ASCII, but the question is what is wrong with this.  Be specific. 

UPDATE2: People are swirling around it.  Several people have identified a problem between 0x1B0 and 0x1CF, and yes, it should correctly spell "compressed".  One person went so far as to send what the correct Hex should be, but that's just the ASCII

What does the incorrect hex mean?

Both other problems can be found by examination of the hex values between 0x1B0 and 0x1CF.

The values at from 0x1F8 to 0x1FB were incorrect as a few people pointed out. Apparently I got a little carried away with the delete button when I was removing the end of MBR signature.  :)  This was not one of the errors I had intended on you finding so kudos to those who did!
