Not sure where to put this question, so I'll just tick it here.

Yes this question, has been asked, but I want to know about the chances of data loss from this method.

Yesterday I was asked to look at someones computer, they want important files from the hard drive. I discover after getting the drive home that it is NTFS, The folders I want to access are protected folders by the NTFS filesystem. I have little experince with this system.

Not even sure an Admin password has been set but one thing is for sure, NTFS is restrincting my acess to Documents and Settings/user

I finished reading how to use Knoppix and chntpw to change the Admin password since the owners have no clue what the pass is. The problem with the Knoppix method I have is two part.

1) It requires using "Captive NTFS" which they say is experimental and to backup your data first, I can not backup the data because of access permisions. And this person realy wants her files, I cannot risk looseing them. If I could be asured by someone who has tested this method that it works without problems that would make me feel beter about trying it.

2) Some reason my newly built PC is not loading Knoppix from the CD, it simply freezes, or locks at the Penguin. My other PC is very old and locks up prosumably because it dont understand NTFS.

Has anyone tested the Chntpw method with knoppix + Captive NTFS?
Why in the world minght Knopix not work on a brand new PC? (See Specs in sig)
Does anyone have any recomendations? Cannot risk data loss.

Im not realy asking how its done, only whats safe, please no flams, its already hot outside.
