Read/write to ntfs from knoppix

dosnlinux · 06-09-2005, 06:20 PM

I know that writing to NTFS is experimental (just out of curiosity how dangerous is it?) and I need to be able to write to a NTFS partition from Knoppix.

I've heard of 3 ways to share files between Linux and windows:

NFS
Samba
FTP

I've only heard of these working with two separate computers, but could any of them be used to read/write to a NTFS on localhost?

No. Think about it this way, the only reason that you can write NTFS file systems through those protocols is because there is a windows kernel at the other end that can read and write NTFS. If you boot a live linux CD you have a linux kernel which doesn't have the ability to do this, so even with an ftp server running and sharing an NTFS system the kernel on the server side still doesn't know how to write to the NTFS partition.

Bummer

Oh well, I may have access to a NT network server, what would be the quickest way to set up quick file transfers?

FTP since knoppix comes with an ftp client, and then just install a server on the other end. Samba is fairly easy too but not quite as foolproof.

I'm not sure i fully understand your question, but if you are trying to boot a windows machine to knoppix then write to the local NTFS drive, then the answer is yes you can do it.

I wrote a little article about it for an english class last semester.

Knoppix comes with a utility called Captive-NTFS. Captive-NTFS uses Wine to load the native Windows NTFS drivers. Wine (Wine is not an emulator) is a Windows compatibility layer which allows programs compiled for Windows to run on Linux. To start Captive-NTFS click the KNOPPIX menu then choose Utilities and Captive-NTFS. Captive-NTFS will then scan your hard drive for the required Windows Drivers. Once Captive-NTFS locates the required files, it runs them and mounts the drive in read/write mode. In the event Captive-NTFS cannot locate the required files, it will attempt to download them from Microsoft. You will need a connection to the Internet for this. While the files needed are freely available from Microsoft you are required to have a valid Windows XP license to download them. You may be prompted to confirm your license. Once the Drivers are loaded the hard drive will be mounted in read/write mode.

Yes, this is my question.

I had heard of captive NTFS, but heard that there was some reported data loss. I did not feel I could take the risk with this particular computer, so I was looking for a better alternative.

Since you mentioned captive NTFS....
How risky is it?
How can I prevent data loss?
What do I need to keep in mind when using Captive NTFS?

I have actually never done it in anger. just proof of concept for my english class project, I pulled a text file off the windows drive, edited it from knoppix, then put it back onto the windows hard drive and the changes were there when i rebooted to windows.

as for the questions, the answers are all "i have no idea", i just know it can be done.

sorry i cant be more help.
