Recovering deleted files from USB disks on Ubuntu

Everyday we use USB keys to transfer data without transmitting them through the t. The USB keys and portable disks are small, light and their data capacity allow us to move in privacy huge files. This idyll sometimes is broken by a fatal mistake: we unintentionally delete an important file. Normally, if we are smart we recover the erased file in the Trash but in other situations when we realize the mistake we had made is too late.

In this circumstances is very import to stop to use our USB key or portable disk till we are able to use a good software for data recovering. On Ubuntu you have a wise number of dedicated software that can do this job for you, the most powerful run on Terminal as testdisk, foremost, and scalpel but you can also use a “minimal GUI” software as PhotoRec.

PhotoRec is very intuitive to use and it is able to recover many data formats from jpeg to db. After you install it using Synaptic Package Manager or the Software Center you can launch it in Terminal with:

sudo photorec

Immediately a GUI Terminal interface appears and you have just to follow the instruct  ions you visualize on your monitor.

Using the arrows and the Enter keys you have to:

1 – Choose the USB device from where you want to recover the data

2 – Select the partition table (usually Intel)

3 – Specify the partition table

4 – Select the right filesystem where the data were stored

5 – Decide if you want to try the data recovering from all the free space

6 – select the directory where you want to store the recovered data. IMPORTANT: do not store the recovered data on the same USB key you are scanning for recovering

7 – Wait till PhotoRec finishes the recover operations.

PhotoRec is fast and, during our tests, we were able to recover almost the 100% of data. Not bad!!! AddThis

Sendoid: share your file through torrents

The first time I read about sendoid.com I was really interested about the services offered by this site. In fact, the possibility to share files with my friends regardless dimensions through a torrent protocol appeared to be very useful.

Unfortunately, in my personal experience the results are not so positive as promised by Sendoid.com. When you decide to try it, you can choose between the online version and the desktop widget built on the Adobe AIR technology. The widget installation is easy, graphically nice and simple to use. Furthermore, the online interface is very well structured in few clicks you are able to “build” the torrent url to share your file directly from you PC to other people through torrent protocols. For this reason, if you decide to use the online version, you are not allowed to close the webpage with the url because it is the “door” to keep the torrent working.

The first problem is that the data are not protected by https and you can only decide to add a password to your file. On the other hand, with just one click you can decide to share the file with more than a person.

The second, big, problem you have with Sendoid is the transfer speed because, in my tests, the service was not so competitive in terms of timing. A light 160MB ISO needed more than 20 minutes to complete its transfer from my computer to another located in a near city. Unfortunately I was not able to understand if this specific problem was related to the ISPs or to the sendoid service but I obtained the same results in different extra tests I decided to try with similar files.

To conclude I decided not to use sendoid and now I am looking for another program or website which could offer similar features. Please, if you have something to suggest, do not hesitate to add a comment! AddThis

Try Lib-Ray: “Sintel” Lib-Ray PROTOTYPE v0.2

The following text comes from: http://www.archive.org/details/sintelLib-rayPrototypeV0.2:

‘The Sintel PROTOTYPE of the Lib-Ray free/open fixed media format for high-definition video without DRM or other “anti-features”. Since it is a prototype, it comes with no guarantees about stability or compatibility, but it is best viewed using Google’s Chromium web browser in full-screen mode on a system with a 1920×1080 “full HD” screen. Some features do not yet work even on this configuration, however, as they require elements of HTML5 that are not yet implemented. Because it’s a short movie, the ISO is relatively small (2.1 GB), and it will fit easily onto an inexpensive single-layer DVD-R disk”.

More details about the project are also available from the Lib-Ray site: http://lib-ray.orgAddThis

Another way to share files between Ubuntu and Windows

This tutorial will show you another way to share and to access the network share folders between Windows and Ubuntu machines. When file sharing is enabled, both systems can access files and folders on any of the PCs. Users with accounts on Ubuntu systems will also be able to access the content directly from your home.

1. To begin, you will need to log on to your Windows operating system. Click ‘Start’ -> search for ‘Network and Sharing Center’ and click on it.

2. Access the ‘Change advanced settings sharing. ” option.

3. Enable file sharing and backup as well.

4. At this point, you need to switch your operating system to Ubuntu. Once you log in, click on ‘Ubuntu menu -> System Tools ”

5. Then select ‘Ubuntu Software Center. ”

6. Find and install ‘Samba‘. This software is required for a better compatibility between the two operating systems.

7. After Samba is installed, you should go to ‘System → Administration –> Samba’.

8. Then click ‘Preferences -> Server Settings’.

9. Write the name of the workgroup you set for your Windows PC(s). If you do not know the exact name because you did not set it, the default name for Windows Workgroups is set to ‘WORKGROUP‘ (capitalizing is not required, however, since Windows is generally not case-sensitive). AddThis
