I'm running Mandrake 9.2 (just reinstalled because things got too complicated!). so I have a fresh install, but for some reason it has mounted all my NTFS (windows) partitions as read-only. I tried removing the "ro" bit in /etc/fstab but after a reboot I still can't modify files on the NTFS drives. here's my /etc/fstab :


[root@dogma temp]# more /etc/fstab
/dev/hda5 / ext3 defaults 1 1
none /dev/pts devpts mode=0620 0 0
/dev/hda7 /home ext3 defaults 1 2
none /mnt/cdrom supermount dev=/dev/scd0,fs=udf:iso9660,ro,--,iocharset=iso8859-
1 0 0
//bias/fileserver /mnt/fileserver smbfs username=% 0 0
/dev/hda1 /mnt/win_c ntfs iocharset=iso8859-1,umask=0 0 0
/dev/hdc1 /mnt/win_c2 ntfs ro,iocharset=iso8859-1,umask=0 0 0
/dev/hdd5 /mnt/win_c3 ntfs ro,iocharset=iso8859-1,umask=0 0 0
none /proc proc defaults 0 0
/dev/hda6 swap swap defaults 0 0


any help would be greatly appreciated!

Maybe I am wrong, but I thought that you can write only on FAT32 files with Linux. Have a look around here, there is a whitepaper explaining that.

ntfs on linux really only has read support, not write support as of yet (well, very dangerous write support)

if you want windows and linux to write to a partition, make a fat32 partition

If you have a "newer" kernel installen (e.g. 2.5.*) you can enable write support to the ntfs-module.
But as mentioned above, it' s dangerous.

Try using a Windows tool like Partition Magic 8 in order to convert a NTFS partition to a FAT32 partition, and then you will be able to use it in read/write mode.
Caution, some "old" versions like Partion Magic 6 can make your linux system unusable.

Well, linux has write support in kernel-2.6. In distros as Redhat or fedora, u need to compile de module. But, i've tryed that, and mounted as RW, but, till now, no lucky. =

Does anyone knows how to do it? even mounted as R-W i still cant write in NTFS. Even not changing the file size...

Did you also compile the write support? It's a separate option. But why do you want to do it? It's extremely limited. From the linux-ntfs page:
You are much better off using an fat 32 partition or use a windows program that can read from a linux partiton if you want to copy things over to an ntfs partition.

@quatsch : do you really know a Windows program that knows how to read Linux files ?

go to the linux-ntfs page and they list a few. I've never tried them but they are read-only so they won't destroy your data. The page is:

thanks for all the help, i finally re-formatted the windows drive to FAT for compatibility...

also,
@quatsch, @li : thanks for the additionnal info.
