How to Recover Deleted Photos from a Memory Card:

how_to_recover_photos_from_an_sd_card.jpg


We will be recommending PC software here, to help readers recover data from their SD cards. If after connecting the camera, or mobile phone to a computer, the storage on it is not read like a separate drive, users may be required to remove their SD cards from their cameras or mobile devices, and connect them to their PCs via a memory card reader (a laptop built-in card reader on a will also do the trick, though an microSD to SD card adaptor may be required).

The readers should in any case remove the affected SD cards from their cameras or mobile phones immediately, as there is a chance the device will overwrite the delete/ corrupted files when using the SD card.

It's worth noting that while the focus of this how to is SD cards, all of these software will do a great job of recovering files from any kind of media like your hard drive, external drive, thumb drive etc.  

Recuva (for Windows)


Recuva (version 1.51.1063) is a 4.02 MB free download, and works with PCs running Windows 2000 or above. To recover your files from your SD card, load the card on the PC via a card reader, select the corresponding drive in Recuva's drop down menu. Run a scan via the Scan button.

The scan will return a list of files on the card, including deleted or corrupted files, and give you the option the recover the files, using the Recover button.

Pandora Recovery (for Windows)


Pandora Recovery (version 2.1.1) is a free-to-use tool that is a 3.12 MB download. It supports PCs running Windows XP or above. Just like with Recuva, users will need to load their SD card via a card reader, and perform either a Quick Scan or Deep (Surface) Scan to throw up results of deleted and corrupted files. The second option is for formatted memory, and while it is slower, it should turn up more results than a quick scan.

Users can then choose which files to recover from the results by right clicking. Alternatively, users can run the Pandora Recovery Wizard and follow on-screen instructions.

Stellar Phoenix Mac Photo Recovery (for OS X)



The Stellar Phoenix Mac Photo Recovery software (version 6.0) is a 13 MB download, and supports Macs running OS X 10.5 or higher. Users will be required to connect their SD cards through a card reader.

Users can then select the Recover Photo, Audio & Video option, and then select their drive from the left panel. Thereafter, they can either choose the Scan Now or Advanced Scan (for a custom scan) option. The scan will return a list of recoverable files, from which users can choose which files they want recovered, and then click the Recover button. Users can scan the drive for free and preview the files the software can recover, but undeleting files is a paid option. The software is also available for windows.

PhotoRec (for DOS, Windows 9x or higher, Linux, OS X)

A free, open-source multi-platform data recovery software, PhotoRec (version 7.0 beta) is 9.4 MB download (for Windows 64-bit), and works with PCs running a vast variety of operating systems. It comes bundled with TestDisk, an app for recovering lost partitions. Featuring a very basic text-based UI for older operating systems, PhotoRec also features a GUI-based version for newer ones.

In both versions, users will be asked to select the type of file system of the drive, select the relevant drive (after connecting it via a card-reader), and then proceed with Scan option, with the choice of Free (for deleted files) or Whole (for corrupted files). Users can then select the location where recovered files should be saved.

We hope these tools served you well. If you have any suggestions of other data recovery methods you'd like to share with your fellow readers, please let us know via the comments.

Difference between Linux and Windows

Features
Linux
Windows
1.    What is it?
Linux is an example of Open Source software development and Free Operating System (OS).
Windows is the family of operating system (OS) from Microsoft, which is the most famous OS in the world.
2.    Cost
Linux can be freely distributed, downloaded freely, distributed through magazines, Books etc. There are priced versions for Linux also, but they are normally cheaper than Windows.
For desktop or home use, Windows can be expensive. A single copy can cost around $50 to $ 450 depending on the version of Windows.
3.    User
Everyone. From home users to developers and computer enthusiasts alike.
Everyone. From home users to developers and computer enthusiasts alike.
4.    Manufacturer
Linux kernel is developed by the community. Linus Torvalds oversees things.
Microsoft created the Windows operating system, but allows other computer manufactures to distribute their own computers with Windows pre-installed.
5.    Usage
Linux can be installed on a wide variety of computer hardware, ranging from mobile phones, tablet computers and video games consoles,to mainframes and supercomputers.
On PC's desktops, laptops, servers and some phones.
6.    Development and Distribution
Linux is developed by Open Source development i.e. through sharing and collaboration of code and features through forums etc and it is distributed by various vendors.
Windows is developed and distributed by Microsoft.
7.    GUI
Linux typically provides two GUIs, KDE and Gnome. But there are millions of alternatives such as LXDE, Xfce, Unity, Mate, twm, etc.
The Windows GUI is an integral component of the OS and is not replaceable. This can be a con when it comes to Windows 8`s Metro.
8.    File System support
Ext2, Ext3, Ext4, Jfs, ReiserFS, Xfs, Btrfs, FAT, FAT32, NTFS.
FAT, FAT32, NTFS, exFAT.
9.    Text mode interface
BASH (Bourne Again SHell) is the Linux default shell. It can support multiple command interpreters.
Windows uses a command shell and each version of Windows has a single command interpreter with dos-like commands, recently there is the addition of the optional PowerShell that uses more Unix-like commands.
10. Price
Free but support is available for a price.
$50-$450
11. Security
Linux has had about 60-100 viruses listed till date. None of them actively spreading nowadays.
According to Dr. Nic Peeling and Dr Julian Satchell's “Analysis of the Impact of Open Source Software” there have been more than 60,000 viruses in Windows. Anti Virus cost about $20 to $400.
12. Threat detection and solution
In case of Linux, threat detection and solution is very fast, as Linux is mainly community driven and whenever any Linux user posts any kind of threat, several developers start working on it from different parts of the world.
After detecting a major threat in Windows OS, Microsoft generally releases a patch that can fix the problem and it can take more than 2/3 months. Sometimes sooner, Microsoft releases patches and updates weekly.
13. Processors
Dozens of different kinds.
Limited but most (80%)
14. Examples
Ubuntu, Fedora, Red Hat, Debian, Archlinux, Android etc.
Windows 8, 8.1, 7, Vista, XP
15. Gaming
Very few games available natively. Some games can be played through Wine, but often not all features are available.
Almost all games are compatible with Windows. Some CPU intensive and graphics intensive games are exclusive to Windows PC's.
16. User experience
Although there are many GUI applications, most of the work is done through Terminal (a console window), and if a problem arrises GUI is rarely usable to fix them.
Everything can be controlled through GUI and incompatibility problems are rare.
17. Graphics performance
Because hardware manufacturers, such as NVidia, often does not provide documentation for linux developers, drivers can not use full card performance.
Combined with newest DirectX versions and full graphics card support the performance is almost as good as it can get.
18. Company /Developer
Linus Torvalds
Microsoft
19. Introduction (from Wikipedia)
Linux is a Unix-like and POSIX-compliant computer operating system assembled under the model of free and open source software development and distribution. The defining component of Linux is the Linux kernel, an operating system kernel first released.
Microsoft Windows is a series of graphical interface operating systems developed, marketed, and sold by Microsoft. Microsoft introduced an operating environment named Windows on November 20, 1985 as a graphical operating system shell for MS-DOS.
