It is OK to double post here if you have new information, and actually probably preferred to editing an old post, since when you edit an old post it is not flagged as "new" and someone just scanning for new information will not see the edit unless they just happen to come back and read the post again.

You do somewhat reduce your chance of getting a response by double posting, as some members here use the forum feature of finding unanswered posts and responding to them, If you respond to yourself then your post is not considered unanswered.

I don't believe that it is ever safe to write to NTFS with Knoppix, and I consider any NTFS partition written to by Knoppix to be potentially corrupt and even more likely to fail at some unknown date in the future than normal NTFS partitions (and the number of people who come here for help would seem to indicate that is not a rare event even for NTFS untouched by Knoppix). Other have posted that they routinely write to NTFS, so there are certainly different religious views in this area. Some argue that they only do it in an emergency to recover data, but in an emergency is the worst time for a nasty surprise and a lost partition. To me it is far better to use Knoppix read only and recover the data safely, then completely rebuild the partition with Windows tools.

Can't help you with your actual problem though.
