I don't know how you would do it either. More importantly, I don't know how you would determine that the NTFS write was done safely. In the past we have seen that some NTFS writes failed immidately and so it was obvious that they had failed and done further damage to the NTFS oartition. But in some cases they seemed to work for a while and it was only later that massive corruption of the partition table showed up.

If you know what program or dll you need to delete you might try deleting it or replacing it with another copy from another system. And I'm all in favor of someone other than me testing Knoppix 5's claim to be able to write to NTFS safely. I just don't know how you would determine with any comfort level that the write went well and that something isn't waiting to get you. Of course, if you run with a reasonable amount of activity for a month or more with no additional problems then it would seem that that particular write went safely, but the cost if it didn't might be worst than just fixing it by a reinstall now if you have or can make good backups.
