how to change hard disk permissions?

[zhfm622]

I have two hard disks which i used in Windows.
when i installed kubuntu, i didn't format them

now i can view the content but i can't changer their permissions so i can't modify the content.

i tried using "sudo chmod 777 " and "sudo chown -R " but all they said
" /media/sda5: Read-only file system "

and also i can't change that by right-click -> "Properites" ->"Permissions"
any solutions

Mount them read-write?

You can't chmod a Windows partition. You have to mount it with the right parameters.

i checked the link you gave.

But i 'm afraid if i re-mount my windows disk,
can i still use them when i go back to Windows?

Being Windows drives I assume they are in the NTFS format.
In that case you will have to make sure you are running the ntfs-3g driver to have write access!
Check in Adept or Synaptic.

Once you've got ntfs-3g installed, you can use the command "mount -t ntfs-3g /dev/sdxy /media/sdxy", where x is the drive letter and y is the partition number. You can find both in System Settings > Disk & Filesystems.
