Re: [expert] Write to NTFS?
As far as I know there are *no* versions of linux, unix, or other OSes that support writing to an NTFS volume that do not risk damaging the file system. The best you can do, with any assurance that your files will still be there in the morning, is read. There is a utility on the market that will *supposedly* aloow read and write on NTFS volumes from a DOS boot disk, but it is not freeware nor shareware. And, quite expensive at that. --Greg - Original Message - From: Paschalis Pagonidis Hi, I can only read to NTFS but can't write even as root. My Mandrake version is 7.0 (it doesn't support "Write" priviledges to NTFS), but I compiled the new kernel 2.2.16 which supports it. But the problem remains!!! I' ve heard that kernel puts some default priviledges to all files at the NTFS partition at startup. How can I change them?

Possibly, all you need to do is edit /etc/fstab. That said, I am skeptical that you can write to an NTFS volume, either safely or at all. NTFS is an undocumented file system, and changes have been made in the layout of data and metadata in the file system as NTFS has evolved. The most recent change is from NT 4 to W2K, and that is a major change. -- -- C^2 No windows were crashed in the making of this email.

Pascal Grosse The lack of a maintainer is one thing, the lack of reliable information about NTFS is another, and may explain the first. My experience with NTFS is this: for two and a half years until about a year ago I worked for Microsoft as a contractor, to write documentation for the SDK. I was to expand on existing documentation and write new docs for the features new to W2K. I signed an NDA, etc., etc. My experience as a contractor to Microsoft, with alleged access to internal documentation, is that there is no documentation for NTFS. None. The only way to know what NTFS does is to read the source. The source is convoluted and confusing. It is rarely commented, and where it is commented, the comments are often wrong. In short, no-one, not even the microserfs who allegedly maintain the code, know what NTFS actually does. -- -- C^2 No windows were crashed in the making of this email.

Re: [expert] Write to NTFS?
Configure your NFS partition via Webmin. It makes it much easier; you can set the permissions to the file there (read only, rw, etc.). Also, you can limit who sees the volume. One gotcha is that you normally can't mount a NFS volume as root. But using webmin on the computer with the volume, you can disable this option. -- Stephen On Tue, 05 September 2000, Charles Curley wrote: On Tue, Sep 05, 2000 at 10:25:47AM +0300, Paschalis Pagonidis wrote: Hi, I can only read to NTFS but can't write even as root.

Re: [expert] Write to NTFS?
I' ve heard that kernel puts some default priviledges to all files at the NTFS partition at startup. How can I change them? Is that the right solution? If you value your NTFS partition at all, I would *strongly* suggest NOT enabling write on it. It's still marked "very experimental" for a reason. If you use the write support regularly, it's not just possible, it's fairly certain it will screw something up eventually... At least, this has been my experience. Your best bet is to have a fat32 partition in addition to your NT partition for exchanging stuff back and forth. -- Ben Reed a.k.a.
