I second that. I've heard lots about how you cannot write to NTFS.
However, to give you the option, I'll hint that I seen it when I was recompiling my kernel. I only picked the NTFS read option, though (not write, I won't trust it).
If you'd like to mount your partition as read only, try changing your fstab file to this:
/dev/sda1 /media/windows ntfs ro,users,auto,umask=000 0 0
This worked for me... not sure about any "chmod"ing needed on the mount point, but this should point you in the right direction for read-only.
Again, I'll stress: Read/Write on NTFS is NOT a good idea! In fact, the current kernel module only supports writing to the partition under VERY SPECIFIC circumstances (like if you don't change the file size, I think...). Best option: Don't use NTFS read/write. Instead:
-Use FTP or SMB and upload your files to another server
-Write to a FAT32 partition
-Use a Windows tool to read your linux partitions (like extfs, I think is the name on one, not sure).
Hope that helps, and someone please correct me if I'm wrong... I'm still somewhat new to Linux myself..
