Puppy Linux is definitely NOT based on Knoppix. It is not based on any other Linux but independently developed by Barry Kauler. I use both but I use Puppy more often these days.

As to whether you can write to NTFS - I do it all the time with Puppy. There are always warnings but no definitive justification as to why not to. All I know is that there was a rather esoteric write problem when using versions of ntfs-3g in the past. Version 1.2506 (May 200 solved this problem. I don't know whether Knoppix uses a later version but I would have thought so.

Of course, one can never be sure that software is bug free but would I regard ntfs-3g any less trustworthy than Windows itself? I guess we each have to make our own decision on that - but my experience is that I am happy to trust ntfs-3g. Of course, whether one uses Windows or anything else one should keep backups of important data.
