JFileRecovery is a free Java Web Start application that can copy files from damaged storage devices and media, skipping over problematic regions that typically cause copying to fail. If the file is listed, there is a good chance that JFileRecovery can salvage much of the data with minimal corruption. For many media files such as MP3, MPEG, AVI and JPEG, corruption is often not even noticeable.

Copying large video files from scratched CDs and DVDs often results in CRC errors, aborting the process and making transferring the file impossible. JFileRecovery can bypass these CRC errors, with minimal data loss which may only be noticeable as a single bad frame in the video.

What is a CRC Error?

A cyclic redundancy check (CRC) is used to detect alteration of data during transmission or storage. This checking procedure is useful to identify when data is damaged or corrupted.

The most common time you will see a CRC error message is when trying to read data from a damaged CD or DVD. Usually the computer becomes less responsive and you hear repetitive seek noises from the drive for up to a minute. And then, if you are using windows XP, you will encounter the following error message:

Cannot copy [FILENAME]. Data error (cyclic redundancy check)

The copy process is then aborted with no option of retrying to read from the damaged region or skipping over it. This is very frustrating when copying large files because you must try copying again from the beginning.

JFileRecovery provides options to retry or skip bad sectors when copying files from damaged hard drives, CDs, DVDs and Flash media.

If you use Windows Vista you already know how painful is copy or move a large file, well here you have an alternative program to windows copy program.

TeraCopy is a compact program designed to copy and move files at the maximum possible speed, providing the user a lot of features:

• Copy files faster. TeraCopy uses dynamically adjusted buffers to reduce seek times. Asynchronous copy speeds up file transfer between two physical hard drives.
• Pause and resume file transfers. Pause copy process at any time to free up system resources and continue with a single click.
• Error recovery. In case of copy error, TeraCopy will try several times and in the worse case just skips the file, not terminating the entire transfer.
• Interactive file list. TeraCopy shows failed file transfers and lets you fix the problem and recopy only problem files.
• Shell integration. TeraCopy can completely replace Explorer copy and move functions, allowing you work with files as usual.
• Full Unicode support.

You can download this program from here.

This Sunday I was watching Steelers vs Eagles game and I saw a Microsoft’s commercial ad that shows people saying they are PCs. I tried to understand the commercial and the only thing I can conclude is that Microsoft spend a lot of money just to tell us what you, me and everybody already know.

All the people who owns a computer is a PC person; no matter what Operating System you are using (Windows, Linux or OS X) all of them are installed on a PC (PERSONAL COMPUTER) so this is nothing to be a WINDOWS PERSON as Microsoft try to explain.

The other ads with Jerry Seinfeld the only thing they promote is Apple ads, the first thing we all think when we saw this ads is Apple Mac vs PC ads.

What do you think? …

Sometimes I have a lot of problems to copy a large file or directory in windows vista and this becomes a real pain in the a**. Well the other day doing a search I found a website with the solution or at least something that help a little.

When you tried to copy or move a big file you find a stupid screen telling you that windows is trying to calculate the time to calculate the time … to calculate the time he needs to move or copy something. I do not know who was the idiot with this brilliant idea.

Well there are 2 solutions one is:

Open Administrative Mode Command Prompt

Either type cmd into the start menu and use Ctrl+Shift+Enter or right-click the Command Prompt shortcut and choose Run as Administrator.

Turn Off Auto-Tuning

netsh int tcp set global autotuninglevel=disabled

You’ll have to reboot your system, but once you do, the problems should be resolved. If they are not you can always turn auto-tuning back on.

Other way is:

Use Robocopy

Use the Robocopy utility that is included with Windows Vista to copy the files. For example, type the following command at a command prompt, and then press ENTER:

Robocopy source_path destination_path file_name

For more information about how to use Robocopy, type Robocopy /? at a command prompt, and then press ENTER.

Maybe you need to connect your network to terminals in different locations securely using the internet. Well a great tool, an Open Source tool lets you do that in a secure and safe manner.

OpenVPN is the best software to accomplish that. This software used for little, medium and large companies is recognized as the “Best SSL VPN” in 2007 and “Best Open Software Award”.

I had to create a network between 3 offices; Cancun, Mexico City and San Luis Potosi and it took me 15 minutes to do it with this tool.

A virtual private network (VPN) is a computer network in which some of the links between nodes are carried by open connections or virtual circuits in some larger network (e.g., the Internet) instead of by physical wires.

About OpenVPN

OpenVPN is a full-featured open source SSL VPN solution that accommodates a wide range of configurations, including remote access, site-to-site VPNs, Wi-Fi security, and enterprise-scale remote access solutions with load balancing, failover, and fine-grained access-controls. Starting with the fundamental premise that complexity is the enemy of security, OpenVPN offers a cost-effective, lightweight alternative to other VPN technologies that is well-targeted for the SME and enterprise markets.

OpenVPN combines security with ease-of-use

OpenVPN’s lightweight design sheds many of the complexities that characterize other VPN implementations. The OpenVPN security model is based on SSL, the industry standard for secure communications via the internet. OpenVPN implements OSI layer 2 or 3 secure network extension using the SSL/TLS protocol, supports flexible client authentication methods based on certificates, smart cards, and/or 2-factor authentication, and allows user or group-specific access control policies using firewall rules applied to the VPN virtual interface. OpenVPN is not a web application proxy and does not operate through a web browser.

Best of all is that you can use this software on Windows, Linux and Mac OS. So if you want to download it go to main site of OpenVPM or download GUI for  Windows, Linux and Mac OS.
