How to Wipe Free Disk Space in Linux
|
||||
================================================================================
|
||||
|
||||
|
||||
**The following tutorial will teach all Linux users how to securely wipe the free space of a hard disk drive (HDD), solid disk drive (SSD) or USB flash drive, making it impossible for anyone to recover deleted files. **
|
||||
|
||||
In case you didn’t know, when you delete a file from your system, even from Trash, it will disappear and can’t be found anywhere on the filesystem. However, that file is not actually gone, it resides in the free space of your disk drive and can still be recovered with data recovery applications.
|
||||
|
||||
For this tutorial we will provide two methods. The first one uses an application called Wipe Free Space, created by Polish developer Bogdan Drozdowski. In the second method we will use the well known BleachBit software.
|
||||
|
||||
While BleachBit is a graphical application, the Wipe Free Space is a command-line software. However, the developer also created an easy-to-use graphical user interface (GUI), allowing novice users to employ it in order to securely wipe the free space of their disk drives.
|
||||
|
||||
> Editor's note: Before we proceed, it is important to know that the applications will wipe the free space in unused clusters and blocks, in partially used blocks a.k.a. “slack space," as well as the names of deleted files and any other data that can be used to undelete the respective files.
|
||||
|
||||
### Method 1 - Wipe Free Space & Wipe Free Space GUI ###
|
||||
|
||||
The Wipe Free Space command-line application can be easily installed from the default software repositories of your Linux distribution, by using the provided binary file for RPM-based Linux distribution or by compiling the sources.
|
||||
|
||||
After installation, you can download the GUI front-end from [here][1], save it on your home folder, extract it, and double click the run.sh file (or execute sh run.sh in a terminal window) to open the application.
|
||||
|
||||
With the application opened, you will need to add the path to the wipefreespace executable, so click the "Browse" button and search it under /usr/bin/. Then add the filesystem that will be wiped.
|
||||
|
||||
Make sure that you check the "Wipe only with zeros" option on the left side of the window. If you need to add more options, first document yourself on how to use them, because they may crash your drive. Now press the "Start wiping" button to proceed.
|
||||
|
||||
### Method 2 - BleachBit ###
|
||||
|
||||
This is the easy method, recommended for novice users. You can easily install the BleachBit application from your Linux distribution's default software repositories. Open it, and make sure that you check the "Free disk space" option under the System section on the sidebar. Press the "Clean" button to proceed.
|
||||
|
||||
|
||||
|
||||
*The Free disk space option of BleachBit*
|
||||
|
||||
The entire wiping operation will take a long time. You can see the entire progress in the main window. Do not hesitate to drop a comment below if you encounter any issues with this tutorial.

Ubuntu 14.04 LTS vs. Windows XP: Pros and Cons
|
||||
================================================================================
|
||||
|
||||
|
||||
**More and more people are looking towards the release of Ubuntu 14.04 LTS (Trusty Tahr) as the natural Windows XP replacement, so we'll try to present the pros and cons for this decision.**
|
||||
|
||||
A lot of Windows XP users are looking to make a change after their operating system will cease to receive security updates from Microsoft, in April. Like most people who are migrating to Linux, they have a lot of questions about various aspects, regarding its use and its capabilities. The truth is that probably Windows XP users are more scared than they should be, as we will show right now.
|
||||
|
||||
### Installation ###
|
||||
|
||||
If you ever installed a Windows operating system, you will know how to install Ubuntu or any of its flavors. It uses a very simple and straightforward installer that doesn't bother the users with difficult choices.
|
||||
|
||||
The only drawback is that if you want to partition your system you might encounter some names that are not familiar, like swap or EXT4. The good news is that it’s unlikely that you will ever need multiple partitions.
|
||||
|
||||
|
||||
|
||||
*Ubuntu installation*
|
||||
|
||||
### Drivers ###
|
||||
|
||||
Windows users also need to install drivers for new components, like Webcams for example. Some are supported by the operating system, other need manual installation.
|
||||
|
||||
The only driver that you will have to worry in Ubuntu is the one for the graphics card. It’s not quite clear from where you can change it at first and installing a newer one might take some adjusting. The good news is the when you will learn how to add a PPA or how to upgrade your packages, everything will seem a breeze.
|
||||
|
||||
|
||||
|
||||
*Install proprietary drivers*
|
||||
|
||||
### Main interface ###
|
||||
|
||||
Ubuntu is somewhat different from Windows XP in terms of the general interface. Although it’s intuitive, some users might not want to invest the time to learn how to operate a new OS.
|
||||
|
||||
The good news is that Ubuntu has a lot of flavors that are a lot more similar with the way Windows XP looks, like Xubuntu or Lubuntu. Both are based on Ubuntu and feature pretty much the same software.
|
||||
|
||||
|
||||
|
||||

|
||||
|
||||
### Applications and security ###
|
||||
|
||||
Installing applications in Windows XP seem easy, right? Double click on a package, hit next a couple of time (agree to an EULA agreement you don't actually read), and everything is set.
|
||||
|
||||
In Ubuntu things are a lot easier. Just open Ubuntu Software Center and search for the application you want. Click install and you're done.
|
||||
|
||||
Installing applications in Windows XP could be very dangerous, especially after Microsoft will pull the plug and end the stream of security patches. On Ubuntu you will never get viruses or malware, and the number of viruses for the Linux platform is extremely small. Whenever a problem appears, it only takes the developers a short while to fix it.
|
||||
|
||||
The only drawback on Ubuntu is that you might not find all the applications you were used to on Windows XP. Most of the bigger apps are cross-platform, but on Ubuntu you might need to search for alternatives.
|
||||
|
||||
|
||||
|
||||
*Installing applications in Ubuntu Software Center*
|
||||
|
||||
### Gaming ###
|
||||
|
||||
Windows XP might seem a better platform for gaming, but the truth is that most game developers will soon stop to make their software compatible with a dying OS. Valve is putting a lot of effort towards the Linux platform and they are pushing the gaming industry in this direction.
|
||||
|
||||
Steam for Linux got more than 500 games in just one year and there is no sign that they are going to slow down. In the next couple of years, the Linux platform will surely be on par with any Windows OS. Adopting Ubuntu now and getting used to it, if you are a gamer, might a great idea.
|
||||
|
||||
|
||||
|
||||
*Portal 2 in Linux*
|
||||
|
||||
### Conclusion ###
|
||||
|
||||
If you are a Windows XP user and you have doubts about adopting Linux and Ubuntu, you might want to think twice about your decision to upgrade to Windows 7 or 8. Linux has it all and there is no good reason not to want an operating system based on it.
