CentOS-5.7 using fuse-ntfs-3g
I have a HDD from a laptop that is being returned for repair replacement. I wish to remove certain files before sending the laptop back with the HDD.
I have mouunted the HDD on my desktop as an ntfs filesystem using an external SATA / USB adapter. As root I then used the gnome desktop to move the desired files to trash. Now I wish to delete the contents of the trash folder and the folder itself. This I cannot do. I have tried deleting using rm -rf ./.Trash-root but the command simply has no effect. It raises no error and it does not remove the Directory or its contents.
For convenience I renamed the directory to DeleteME using move, which worked. As expected through, all attempts to remove DeleteME still fail silently. The permission bits are set thus:
dr-xr-xr-x 1 root root 488 Oct 21 10:54 DeleteMe
I have tried chmod -R 777 DeleteMe but this has no effect on the permissions.
How do I get rid of this thing?
I realize that after the trash directory is removed I will still have to over-write the unused space on the drive to scramble the contents but I cannot get to that stage until I free the space.
How about put the HDD back in the laptop, download and burn dban ( http://www.dban.org/download) to a CD and boot the laptop to the CD?

There is also Hiren's Boot CD with ton of tools and even Mini Windows booted from Hiren's Boot CD not touching the HDD.

Ideas: 1) Try in runlevel 3 ie without gnome/X running. 2) If selinux is running on the desktop, set it to permissive. 3) What does the output of mount command say about the ntfs partition? 4) What options did you specify when mounting the ntfs partition? 5) Have you considered the mount options for ntfs as documented in man mount?

The situation is resolved. The laptop was dead and unrevivable. Our internal network policies forbide attaching any recorded media that have been outside the gateway. (The laptop was the president's, which is the only reason it got on-site to begin with, sigh.)
In the end I had to mount the drive in an external usb housing and plug it into a windows box segregated from the network. I discovered in the process that the read only bit is ignored by windows when it is set for a directory. I also discovered that using deltree from the windows cli leaves ghost folders where the files have been removed but sub-directories have not.
Eventually I got everything off, the space marked as clean, and then wiped repetitively over the weekend.

You say that the disk is formatted as NTFS, presumably for use with Windows, yet you mention deleting the files with the Gnome desktop and then deleting them from .Trash. I'm therefore very confused about how you're trying to delete the files.
If the files to be deleted are in a NTFS filesystem which is mounted under Linux, simple delete them. Since Windows isn't running, they won't be moved to Windows's trash directory, called $Recycle.Bin.
I think that you should be more concerned about deleting Windows's swap file (pagefile.sys), $Recycle.Bin, and the directory \System Volume Information, and then overwriting the free space. Even better, if the disk is to be replaced, why not overwrite the entire disk using shred?

He is saying, which I think i also have seen on my USB Flash drive, system immediately re creates Trash folder. He would like to delete it and unmount without recreating Trash folder.
Best course of action is to return HDD to it's PC, boot up and then delete Trash folder.

I just re-read his original post. I made a wrong assumption.

This is still best thing to do.

I've seen your correction, but I still don't understand where this .Trash-root directory comes from.
The user says that he's running CentOS 5.7 and Gnome, but under Gnome the trash directory is simply named .Trash, not .Trash-root, and deleting a file from an NTFS file system mounted under Linux doesn't move it to .Trash.
Anyway, I think we can all agree that if the hard disk will be replaced, it's better to overwrite the entire disk, using shred or dd (as John R. Pierce suggested), or a Windows utility.

My observation is that .Trash is for normal users and .Trash-root is when you delete as Root. I sometimes use Krusader (under Gnome) in root mode, and that could account for .Thrash-root in my case. Maybe he did something similar.

Try deleting with the -f option. I.e., rm -r .Trash-root. This will at least tell you what the issue is. Once you fix the issue preventing deletion, go ahead and add the -rf (or unalias your rm command :D )..

boot a Linux rescue USB or CD to a shell prompt
dd if=/dev/zero of=/dev/sda bs=65536
this will as quickly as possible zero the entire disk, effectively erasing all files. with modern disks, a single pass of zeros is about as good as it gets, the old multipass secure "DOD" erasure was designed for antique disks that had bits the size of sand grains. even this fast single pass of zeros will take an hour or so to wipe 300gb.
or, if you've connected this disk to a linux PC with a USB adapter or whatever, do the same command, replacing sda with the correct physical drive (no partition numbers)
