Hi and Welcome !

There is no need of shell programming. All you have to do is, mount NTFS partition with read/write privileges. You have to edit /etc/fstab file for that.

Execute this in Terminal/Konsole :

su -
fdisk -l
cat /etc/fstab

Post output here.

* Its small L in fdisk -l.

[devils casper]

Open /etc/fstab with root privileges and edit ntfs lines.

/dev/hdc1 /mnt/win_c ntfs-3g defaults,umask=0 0 0
/dev/hdc5 /mnt/win_d ntfs-3g defaults,umask=0 0 0
/dev/hdc6 /mnt/win_e ntfs-3g defaults,umask=0 0 0
/dev/hdc7 /mnt/win_f ntfs-3g defaults,umask=0 0 0

Save file and reboot machine.

Thank you, but i dont know how to edit that file with root preveledges.

on top of that now i am having another error it says : "File or Folder /mnt/win_c does not exist" when i am trying to open my Drive C using konqueror. this is happening for all the NTFS partions.

But when i can view all my file within win_c from the terminal using ls.
please help.
thanks.

Execute this

su -
cd /mnt
mkdir win_c win_d win_e win_f 
nano /etc/fstab

su - is for gaining root privileges. mkdir command will create folders in /mnt and next command will open /etc/fstab file in nano editor.

Edit contents of /etc/fstab as I suggested earlier and press Ctrl+X, Y and hit Enter key to save file. Reboot machine. Check folders in /mnt.

In case it doesn't work, post the output of df -h command here.

[JeetNayan]

Thank you...

I will do as you have told.. another thing should i remove the existing Win_c, win_d etc.. directories existing under /mnt ??

[devils casper]

If directories having same name already exist, mkdir command will throw an error. Linux is case sensitive. Make sure to use proper case. Folders name in /mnt and /etc/fstab file must be same.
If you are creating Win_C folder then it must be /mnt/Win_C in /etc/fstab file instead of /mnt/win_c.

[JeetNayan]

Thank you ,

I did as you have told but the problem persists : when i try to open any of my NTFS partitions using konqueror is says "The file or folder /mnt/win_d" doesnot exist, this is same for all my windows partitions c,d,f.

Where as when i open /mnt/win_d from the terminal i can view all the files inside /mnt/win_d using command ls.

The output of df -h :
