ok, My personal crashed! my hard disk has window vista and it “crashed” , basically i can't access my files, so now

i am booting ubuntu live to see if i can access my files on sda1 and copy them to my external hard disk, however i get this error message:

$LogFile indicates unclean shutdown (0, 0) Failed to mount '/dev/sda1'; Operation not support Mount is denied because NTFS is marked to be in use.

how do i mount the hard disk? what are the comands so i can do it on the command line? any recommendations will be highly appreciated,

Answer:
I think ubuntu give you that message because windows wasn't properly shut down the last time you used it. You could try safe mode on vista by pressing F8 when booting up the personal. (All you have to be able to do is start vista and reach the login screen in safe mode and select shut down. This will properly shut down and grant ubuntu to access the files.
