CD DVD Data Recovery Software Overview

by Arun 27. August 2011 07:46

Blank CDs and DVDs have been around for quite some time now and their limited life span means that many users will eventually run into accessibility problems. With age come problems to read files from the CDs or DVDs. The only option in this case is to make use of data recovery software to save those files to storage device before they become completely unrecoverable.

Why can files become unreadable on optical media? Burned CDs and DVDs suffer from material degradation. And most disks also suffer from oxidation, not to mention scratches and other forms of physical contacts. The average lifespan of such disks is said to be ten years.

This overview looks at free solutions to recover files from CDs and DVDs.

It should be obvious that data that is not there anymore physically cannot be read by even the best DVD or CD recovery software. Sometimes though files can not be read by the user in Windows, while they are largely recoverable on the byte level. Basically, data recovery software copies every readable byte of the optical disks to another storage device.

IsoBuster

isobuster

isobuster

What the developer says:

It supports all optical disc formats and all common optical disc file-systems. Start up IsoBuster, Insert a disc, select the drive (if not selected already) and let IsoBuster mount the media. IsoBuster immediately shows you all the tracks and sessions located on the media, combined with all file-systems that are present. This way you get easy access, just like explorer, to all the files and folders per file-system. Instead of being limited to one file-system that the OS picks for you, you have access to “the complete picture”. Access data from older sessions, access data that your OS (e.g. Windows) does not see or hides from you etc.

IsoBuster is available as a free and professional edition. The free version has several limitations, largely lack of HD DVD, Blu-Ray and file format support.

The program tries to install a toolbar during installation, make sure to cancel that before continuing. The program is simple to use. It will automatically recognize a CD or DVD that has been inserted into the drive. The sessions, tracks folders and files are displayed in the program interface.

Here it is possible to navigate the menu structure, and extract individual files or files from folders from the disk. IsoBuster displays a Save As dialog and extracts the data to the selected disk.

Several recovery options can be configured in the preferences. This includes the maximum number of retries, sorting criteria, file system specific settings or image files handlings. IsoBuster can load CD and DVD images as well, which is the recommended way of handling recoveries.

CD Recovery Toolbox

What the developer says:

CD Recovery Toolbox Free – repair damaged CD disks

CD Recovery Toolbox tool was developed for recovering damaged files from different disk types: CD, DVD,HD DVD, Blu-Ray, etc. You can use it to restore information lost as a result of some mechanical damage of the disk (scratches, chips, different spots on thesurface) or as a result of incorrect recording.

This program is very easy to use. CD Recovery Toolbox supports recovery of CD, DVD,HD DVD and Blu-Ray disks. It begins with the selection of the drive, and the output directory. The program then reads the files from the disk and displays them in a file browser.

Here it is possible to select the root folder, or one of the subfolders of the disk for recovery. A click on Save reads the data from the disk and saves it on the selected storage device.

CD Check

cdcheck

cdcheck

What the developer says:

As your CD and DVD collection grows, there are two important problems you face – do your CDs and DVDs still work? What can you do when a CD or DVD starts to have problems? These are crucial questions since the discs are used to store valuable files like email, home movies, photographs, business/tax records and music. The solution is to use a free program like CDCheck. It can scan most CDs in a few minutes to tell you if the data is OK – this way, you don’t have to find out the hard way that there is a problem. Plus you can use the time it takes for a scan to complete as indicator of the CD or DVDs overall health – even though files may not be recorded as damaged, slower results normally indicate a CD that is on the way out (expect longer times if there are more files on the CD).

If a CD or DVD is showing files with damage or you can no longer read a file in a drive, CDCheck can be switched to recovery mode and make a full sweep of the CD or DVD, recovering lost files along the way. When parts of a file can’t be fully recovered, the program will still recover any salvageable fragments. Many file formats such as Zip, TIFF and JPEG can still be used if incomplete (success of this technique varies, depending on the damage). Most zip tools have a ‘repair archive’ function, and a standard graphics editor can help repair damage to photographs caused by missing fragments.

CD Check is a software that needs to be registered on the developer’s homepage before it is free to use for a lifetime. The program can check a disk for read errors, which the other programs in this overview cannot. The time of each check depends on the disk and the speed of the drive.

The other options are to compare directories, for instance a directory on the CD or DVD with a local directory, and to recover files from the disk. For comparison purposes, hashes are generated.

DVD Disaster

dvd disaster

dvd disaster

What the developer says:

CD, DVD and BD media keep their data only for a finite time (typically for many years). After that time, data loss develops slowly with read errors growing from the outer media region towards the inside.

Archival with data loss protection

dvdisaster stores data on CD/DVD/BD (supported media) in a way that it is fully recoverable even after some read errors have developed. This enables you to rescue the complete data to a new medium.

Data loss is prevented by using error correcting codes. Error correction data is either added to the medium or kept in separate error correction files. dvdisaster works at the image level so that the recovery does not depend on the file system of the medium. The maximum error correction capacity is user-selectable.

DVD Disaster is not a typical data recovery software, as it can be used to prevent data recovery by adding error correction codes to optical disks. To create error correction codes a disk image is required. The program is able to create those disk images and create the codes. Those codes can then later be used to recover files from a disk.

Roadkil’s Unstoppable Copier

unstoppable copier

unstoppable copier

What the developer says:

Recovers files from disks with physical damage. Allows you to copy files from disks with problems such as bad sectors, scratches or that just give errors when reading data. The program will attempt to recover every readable piece of a file and put the pieces together. Using this method most types of files can be made useable even if some parts of the file were not recoverable in the end.

The program can be used as a daily backup system using its batch mode functions. A list of transfers can be saved to a file and then run from the command line to perform the same batch of transfers on a regular basis without having to use the GUI interface. The program supports command line parameters which allow the application to be run from schedulers or scripts so it can be fully integrated into daily server tasks.

Roadkill’s Unstoppable Copier can read data from any kind of disk. It tries to recovery files on a byte level, and can copy files partially because of this. This often means that files can still be accessed, especially if they are not binary.

Abyssal Recovery

abyssal recovery

abyssal recovery

What the developer says:

Abyssal Recovery can rescue corrupted or lost data from damaged, scratched, or defective CD and DVD discs. Abyssal Recovery can copy the files to another destination on your hard drive. Abyssal Recovery will skip the bytes which are not readable from file and copy all other bytes to extract maximum data. You can set the program to copy byte with byte to minimize the losses, or you can set a higher number of bytes to be copied once for a faster recovery.

Abyssal Recovery is a basic CD and DVD data recovery software that tries to rescue data from partially unreadable disks by copying all readable bytes to another storage device. It does not offer an advanced feature set as several of the other recovery solutions in this guide.

Verdict

Two of the tools in this review can be used to prevent data loss. Both CD Check and DVD Disaster offer the means to check data on disks regularly to ensure 100% readability of the data. DVD Disaster even offers a solution if data becomes unreadable.

For disks with corrupt data, IsoBuster is probably the prime choice. Even though it may make sense to use several tools for best recovery results.

Have you encountered unreadable disks in the past? If so, what have you done to recover the data on them?

Facebook Improves Photo Feature

by Administrator 27. August 2011 07:38

It is an incredible number; The 250 million photos that get uploaded to Facebook every day. Imagine that: 250 million photos. That’s a lot and some Facebook users must really be active in this regard.

The current photo viewer on the social networking site has caused lots of controversy since its introduction. Facebook users who did not like the photo viewers interface or functionality at all may be glad to hear that Facebook changes the layout and functionality of the Facebook photo viewer once again.

The company introduced the new features on the official Facebook blog. To sum it up: Three core changes are introduced in the new photo viewer.

Photos can now be shared with a resolution of up to 960 pixels in width, which does not look like much on first glance when compared to the existing solution of 720 pixels. Take a look at the photo below to see the difference in action.

facebook photos

Even better: Despite the increase in size, loading times of photos have been cut in half. Photos on average should load now twice as fast as before which means that Facebook users can access larger resolution images faster on the site.

Photos that have already been uploaded by the user will automatically be displayed in the new higher resolution.

The third and final change is a new photo viewer which on first glance looks a lot better than the current viewer. The new viewer puts the focus on the image. Instead of displaying the image on a black background, it now displays on white which is a lot easier on the eyes.

The clean interface is still displaying comments and other options (like tagging) below the photo on the photo viewer page. Here is a sample shot.

facebook new photo viewer

I personally like the new photo viewer and the fact that photos now load faster on Facebook.

The features are currently being rolled out to all users. It make take a few days before you get access to them in your account.

47 Percent of Small Businesses Use No Social Media Only 12 percent call it a "must." 14 percent say they don't know enough about it.

by Administrator 22. August 2011 05:26
social media That’s according to a just-released survey of more than 300 businesses with fewer than 250 employees conducted by Opinium Research and sponsored by Hiscox, a small business insurer. Of those that do use social media, Facebook led with 19 percent, followed by LinkedIn at 14 percent, and Twitter at 4 percent. Only 12 percent described social media as a “must,” saying they use it daily. Twenty-four percent say they do it when they have time, and 14 percent say they don’t know enough about social media. So what do they do instead? Mostly non-virtual networking. Half of all respondents said they could not do without word-of-mouth referral, and 40 percent said it is their main way of acquiring new business.

How to use Google Webmaster Tools

by Administrator 11. August 2011 10:33

Web crawl errors

Web Crawl errorsOn opening Google Webmaster Tools I select a site. If you do that, the first thing you see is the diagnostic tab, with in it an overview of the latest web crawl errors Google encountered. This is the first thing I check out, as it provides very important data on the current status of the site. If you have a lot of URL's that are either not found, unreachable, or timing out, you should look in to those and fix them. URL's that aren't found might be caused by people linking to you making an error in typing the URL. You could either ask those people to change that URL, if you know who is linking to you like this, or 301 redirect the page that Google didn't find to the correct page. Be sure to check out all errors, and make sure you click all URL's to see what happens.

The crawl rate

The second thing I look at is the crawl rate, linked in the menu on the left under tools. In this page, you want to see this box:

Crawl rate

You want to be sure that Google does not want to crawl your site faster, if it does, you can put it to faster. If that's the case though, chances are that your visitors aren't experiencing a fast site either. So you want to speed up your server, or get your hosting provider to speed it up.

Above this box is an overview of the Googlebot activity over the last 90 days. Check out the graphs that are hidden underneath the links, and make sure that the number of pages crawled per day and the number of kilobytes downloaded per day isn't going down drastically, but also don't obsess over slight downward movements. You also want to make sure the time Googlebot spends downloading your pages is "stable".

Statistics

The next tab is the statistics tab. When you open this, the first thing you'll see is a table showing "The PageRank of your pages in Google", and a table showing the page with the highest pagerank for the last three months. I don't think this data is very interesting, especially because PageRank is only shown as High, Medium, Low or "Not yet assigned". If these things change heavily though, and you weren't expecting them to change, you might want to take a look at your IBL's.

Something else in this tab is a lot more interesting, though you might have gathered this data using other tools. Under "Page analysis", there are two tables showing the common words for both your site's content, and the common words in external links to your site. If you consider that the anchor text used for links towards your site is a very important factor in your rankings, you understand that this is an important table to have a look at. Any keywords that you're targeting that aren't in there? Perhaps you should think about your link building strategy again...

The Links tab

The tab with, in my opinion, the best information in Google Webmaster Tools for an SEO is the links tab. This shows an overview of all the pages on your site which Google has found links to, and the amount of links it has found to these pages. Clicking on the number next to the page URL shows the specific page Google has found the link towards that page on. If you use the extension I created, Google Webmaster Tools External Links++, you will also get the anchor text for the link and the PageRank for the page linking towards you.

I use this data regularly to check on which links Google has indexed, and how many links I have gathered with my new tools, link-bait actions etc.

Conclusion

If you use Google Webmaster Tools like this regularly, you'll be aware of any (indexing) problems with your site in time, and have a thorough understanding of how your site is doing. Make sure you add this to your weekly routine!

Google Search Engine Optimization

10 Ways to Increase Your Site Crawl Rate

by Administrator 11. August 2011 10:07

Regular and frequent visits by the crawler is the first sign that your site appeals to Google. Thus the most efficient way to get frequent and deep crawls is to develop a website that search engines see as important and valuable.

Note that you can’t force Googlebot to visit you more often – what you can do is to invite it to come. Possible measures to take to increase the crawl rate may include:

  1. Update your content often and regularly (and ping Google once you do) – well, an obvious one, so not much to describe here; in a word, try to add new unique content as often as you can afford and do it regularly (3 times a week can be the best solution if you can’t update your site daily and are looking for the optimal update rate).
  2. Make sure your server works correctly: mind the uptime and Google Webmaster tools reports of the unreached pages. Two tools I can recommend here are Pingdom and Mon.itor.us.
  3. Mind your page load time: note that the crawl works on a budget – if it spends too much time crawling your huge images or PDFs, there will be no time left to visit your other pages.
  4. Check the site internal link structure: make sure there is no duplicate content returned via different URLs: again, the more time the crawler spends figuring your duplicate content, the fewer useful and unique pages it will manage to visit.
  5. Get more back links from regularly crawled sites.
  6. Adjust the crawl speed via Google Webmaster tools.
  7. Add a sitemap (though it’s up for a debate whether the sitemap can help with crawling and indexing issues, many webmasters report they have seen increased crawl rate after adding it).
  8. Make sure your server returns the correct header response. Does it handle your error pages properly? Don’t make the bot figure out what has happened: explain it clearly.
  9. Make sure you have unique title and meta tags for each of your pages.
  10. Monitor Google crawl rate for your site and see what works and what not:

How To Ask GoogleBot (Google) To Crawl Your Site

by Administrator 11. August 2011 09:50

How can you induce GoogleBot into crawling your site.

Although there is no magic shot that guarantees inducement of the crawl you can always increase your chances of that crawl in a few ways.

  • Submit a Sitemap file to Google Webmaster Tools
  • Make sure you have plenty of links pointing to your site from pages that are already in the Google index
  • Build out a real sitemap for users
  • Make sure you have a search engine friendly site
  • Increase the crawl rate at Google Webmaster Tools to "Faster"

I am sure there are many other ways to help induce a crawl, but here are just a few good ways to do it.

WordPress Crawl Rate Tracker Plugin

by Arun 11. August 2011 09:43

With the advent of Google Analytics and other JavaScript based solutions a lot of webmasters have lost the ability to easily analyse log files to see how search engines are interacting with their site. Update: A new version of this plugin compatible with WordPress 3+ is now available here. Google Webmaster Central offers a nice graphing feature so you can see the crawl trends but there is no way to access meaningful data. Studying crawl rate is hugely important because it helps you find out which pages are trusted most by the search engines (especially Google). The more Google trusts a page the greater the frequency it will re-visit that page. If you build a few deep links and see your crawl rate for the target page suddenly increase you can be confident that the links are highly trusted and that you should try to get some more. Today we are releasing a plugin for WordPress that allows you to track crawl activity for MSN, Yahoo & Google from your dashboard. Access crawl data for 3 main search engines See the exact times a spider accessed any page on your site Monitor your crawl rate over time Discover how crawl rate is related to PageRank Download the plugin here.
