Why I need input password when LXDE mount NTFS disk

[moreo]

I have 2 system in my laptop:win7 and lubuntu

After login in,first time when I open the NTFS disk by PCManFM,it give me a box to input the password,next time will not.
But when I restart the computer and login in, the case will happen once again.
Yes, after each login in,it need the password when the PCManFM first mount NTFS disk.
How can I cancel the step and access the NTFS disk directly?

Welcome to the lxde forum. The requirement to inpute your password is for your own protection. Should you want to access files on your NTFS partition without entering your password then see this thread on the Ubuntu forums:
