Does anyone know of a Linux program or method to wipe/secure delete the free space only from a NTFS or Ext3 drive?
A faster way to wipe free space?
location: linuxquestions.com - date: February 1, 2009
On my Windows PC I can use PGP's wipe utility to securely wipe free space on the disk and do it in a reasonable time. A one pass wipe of 130 GB on a 320 GB SATA drive takes about 1 hour. On the same drive on my Linux box - same drive model and about the same processor - wiping the same amount of space with sfill (from secure-delete) failed to complete a single pass in 8 hours. It was still working.
Can anyone recommend a Linux product which will wipe free space in a little more timely manner?
p.s. I have tried using dd to copy /dev/urandom to a file to fill the unused space. This again takes an unacceptable amount of time. Filling a fixed size file with /dev/urandom (I have tried various sizes) then making enough copies of the file to fill the disk is a little faster but still not up to what PGP can do.
Howto: Wipe free space with Bcwipe
location: ubuntuforums.com - date: October 21, 2006
Just decided to throw this out here if anyone is interested in wiping free space on Linux. It wasn't meant to be a how to, so sorry if it isn't that 'deep'. I was going to put it in cafe, but didn't want it to disappear so easily.
Bcwipe is a proprietary file wiping program, but it can also wipe free space and file slacks. Since I could not find any easy information about doing that on Linux, this may be a good option if you are interested. It uses Peter Gutmann (automatically I think), DoD, or your own defined number of wipes.
1a. Download alien converted rpm to your desktop-
1b. Or download the latest rpm-
sudo apt-get install alien (if alien is not already installed)
sudo alien --to-deb -v BCWipe-1.6-4.i386.rpm
2. Unpackage and install.
sudo dpkg --install bcwipe_1.6-4_i386
BleachBit Can't Wipe Free Space
location: ubuntuforums.com - date: July 1, 2011
I have a 500 GB hard drive connected via a SATA/USB adapter. After connecting it, I did a basic format of the drive with no problem. I then attempted the "Wipe Free Space" option under the File menu in BleachBit, selecting the external drive, and it began the process. It gives me a time estimate of about 300 minutes, but, instead, after a few minutes it says "Done" and gives me the message "[Errno 27] File too large. Disk space recovered: 0 Files recovered: 0 Errors: 1"
What happened? What do I need to do to get this volume wiped? Thanks.

Can someone please give me simple detailed instructions on how to wipe the free space on my hard drive. I have a Ubuntu/WXP dual install. It is very easy to do this in Windows as there are several free software tools to do it. Is there anything like this in Ubuntu?

writing code to wipe free space and do secure file delete
location: linuxquestions.com - date: October 28, 2014
i have an interest in writing a C program that does (a) wipe free space in a partition and (b) securely delete file(s).
It would be cool if I could accomplish this on any file system, but for starters i would like to just get it working on NTFS.
my initial thought is to have a running linux box, running opensuse or SLES 11, compiling with gcc.
the general scenario would be a hard drive in a windows 7 pc, where I want to do either (a) or (b) on. I would shut pc down and remove hard drive then slave it on my linux box, then run my wipe program on.
looking for ideas on how to do this.
Wipe Free space on hard disk drive using C#
location: linuxexchange.com - date: January 14, 2010
I have been tasked to overwrite all the free space on a few laptops 3 times. I know there are some alternatives but I like to know how things work and if I can to do it myself with C#.
1) yes, I know there are plenty of freeware applications that will do this
2) no, we don't need to conform to any specific government standard
Where do I look for ideas on how to start this?
Thanks if you can point me in the right direction.
Can it be achieved using C#? If so, how?
Free Space 2 is Open Source and running in linux!!
location: ubuntuforums.com - date: July 31, 2006
I wrote a little digg with some links to other information sites. Be sure to read the first comment, since that is where the other links are!
I got this running over the weekend on my home Ubuntu (Dapper). I haven't installed all of the upgrades, but I have enough installed to be impressed. It plays great.
Just in case somone wants to try it out, I'll give a brief synopsis of what I did.
I basically followed the Free Space 2 Open Wiki
I have the actual Free Space 2 disks, so I extracted the files from the cd that way. After that, I got the source code from cvs. It seemed like the easiest way. i had no issues compiling (I did not perform anything other than the most basic compile.)
Fair warning. The information is spread out and hard to locate. So, use the forums, and ask questions.
Lemme know what you think of this.

Is it possible for me to allocate free space to my Windows partition without having to move the entire Ubuntu partition to the right?
Thanks in advance.
