I'm not a programmer, but have been folowing the development of ntfs driver. An Idea I've had for a while on working write code... A boot floppy that can be found through astalavista is a NT password changer and registry editor. It obviously has write back support. I've never had it destroy the filesystem, either. The author claims it's been tested on NT, 2K, 2Ks. I've also ran it on XP, and it worked fine. I remember the NTFS driver for Win9X being brought up... why not look into an NTFS driver already on a linux system? ---Brad __________________________________________________ Do you Yahoo!? Yahoo!

Some notes, - NT password changer only makes some minimal changes to some data on NTFS that's much-much easier than a full featured write driver - it uses Anton's code, ntfsfix from ntfsprogs to schedule a chkdsk at Windows boot and reset journal file to lessen the chance of destroying the filesystem - I'm about 100% sure the NTFS driver is the old one that is known to be very dangerous (a.k.a broken). .... Hmm, I just checked and actually the latest release changed to Anton's driver that has write-over support. In short, you are very lucky and/or it seems the minimal operations needed to achieve by chntpw are working with quite good probability with the old NTFS driver. And the last release uses what's linux-ntfs team is working on. Szaka |

Ah, the floppy is my project :) > > Some notes, > > - NT password changer only makes some minimal changes to some data on > NTFS that's much-much easier than a full featured write driver It always writes back files with the same size, yes. And only a tiny fraction of them have been changed. And only 1-3 files usually. There have been a lot of reports of the old NTFS-driver failing, usually the changes did not take place. Only rarely have people told about heavy corruption because of my use of it. But there are of course people not reporting. > - it uses Anton's code, ntfsfix from ntfsprogs to schedule a > chkdsk at Windows boot and reset journal file to lessen the > chance of destroying the filesystem It did, yes. > - I'm about 100% sure the NTFS driver is the old one that is > known to be very dangerous (a.k.a broken). .... Hmm, I just > checked and actually the latest release changed to Anton's driver > that has write-over support. Yes, I used the 1.6.0(?) patch for 2.4.20 kernel. The write-in-place seems to be more correct. And it also reads much better. But I'll wait and see for the feedback before I can really tell :) Thanks to Anton and all other involved with NTFS! And some off-topic: My next project after adding support for account lockouts/disable and other state flags for the account database (mostly done), will hopefully be full registry write support. I know how, but am just lousy writing code. Then it will also support extending the filesize. And need that too from NTFS-driver. Someone a few years ago used some of my early code to write a registry-filesystem for linux, so that a registry hive can be mounted as a filesystem. I think I've lost that one. Anyone knows who?

The new one shows only this in a frame "Your browser doesn't support inlineframes in its current configuration!". Szaka |

Do you have more feedback? Now I have some feedback on the new ntfs-driver. It basically is: 1) It works as documented. 2) The write just hangs there for some reason (no messages), and after a reset nothing seems written. Sometimes it also says it can't=A0expand some attribute (I'll get the excact text next time if you'd like), even if the file is exactly the same size, even it does actually write the data. The files my tool writes always multiple of 4k in size, and the sam which is the most frequent changed is usually less than 64k. The system hive may on some systems be huge, however, 4-8MB, but that als= o works well most of the time. By the way, I now have full registry edit, except expanding the file itself (currently uses free space inside the file). So full NTFS write support will be good :) > > > Someone a few years ago used some of my early code to write a > > registry-filesystem for linux, so that a registry hive can be mounted > > as a filesystem.
