HELP: Read-only file system? Weird!

cslab:/media #  mount -t ntfs -o rw /dev/sda1 /media/sda1

cslab:/media # mount
...
shmfs on /dev/shm type shm (rw)
usbdevfs on /proc/bus/usb type usbdevfs (rw)
/dev/sdb1 on /media/sdb1 type ntfs (rw,nosuid,nodev)
/dev/sda1 on /media/sda1 type ntfs (rw)

cslab:/media # cd /media/sda1

cslab:/media/sda1 # touch 1
touch: cannot touch `1': Read-only file system

Anybody know why? Thanks.

NTFS module, by default, does not support write operation.

Thanks, sakulagi. You are so nice.

I download the kernel 2.6.12, and compiled it with "NTFS Write Operation" option. Everything works well. But, finally, when I mount ntfs file system.  I got the following problems:

suse:/windows/music # ls
.  ..  IO.SYS  MSDOS.SYS  Music  RECYCLER  System Volume Information  photoes
suse:/windows/music # touch 1
touch: cannot touch `1': Permission denied
suse:/windows/music # ll

drwx------    1 root     root         8192 Jun 26  2003 photoes

I am confused again. Could you tell me more about that?

BTW:
suse:/windows/music # lsmod

ntfs                  183216  -

Thanks a lot.
