mounting NTFS on ubuntu

[Pushparaj Shetty]

Hi all,
Kindly provide the coomand to mount NTFS on Ubuntu 6.10.
 I tried
# mount /dev/sda1 /mnt/C -t ntfs -r

Though it didnt give any error, It says:
You do not have the permissions necessary to view the contents of "C".

Below is my patition list:
 Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1        2550    20482843+   7  HPFS/NTFS
/dev/sda2            2551        5305    22129537+   f  W95 Ext'd (LBA)
/dev/sda3            5306        9729    35535780   83  Linux
/dev/sda5            2551        5100    20482843+   b  W95 FAT32
/dev/sda6            5101        5113      104391   83  Linux
/dev/sda7            5114        5305     1542208+  82  Linux swap / Solaris
