Sometimes, when a ntfs partition is open, or partially corrupted, or it had been bad closed, if you try to mount it, you’ll find an error message telling you that it’s impossible to mount.
Today, I had to help a friend with her computer, wich was infected by a virus or a trojan… and she couldn’t access to her windows partition.
The first I did was use an Ubuntu Live CD (it’s always on my bag ) to mount her Windows partition and move her files to another hard drive. But I always got that error message. Finally typed this command on the Terminal, et voilà:
$sudo mkdir /media/HDD
$sudo mount -t ntfs-3g /dev/sda1 /media/HDD -o force
This only forces the ntfs partition mounting by using the ntfs-3g driver, and it had worked great.
