The 21st century has seen a thrust in progressive miniaturization of every electronic device. The development of handheld devices like cell phones, digital camcorders, cameras, and other such devices, necessitated the development of data storage devices that didn't take up much space and provided adequate storage at the same time. In an effort to provide such devices, SD cards were developed. Loss of data, due to accidental deletion or other such problems, need not be an irreversible phenomenon, in case of these cards.
About SD Cards
Secure Digital (SD) cards are standard storage devices used today, in cell phones, cameras, and even portable computers. Though superseded by the high capacity SDHC (Secure Digital High Capacity) cards, they still remain in use. They provide a maximum storage capacity of 4 GB. If you happen to delete any photos, media files, or other data from your SD card, you can easily recover it by following the instructions presented in the following lines.
Recovering Deleted Files
Almost each one of us faces situations where we mistakenly delete stuff. Thankfully, there is software to recover deleted files. Here is some information to help you out.
On a Mac
Due to the large difference between Windows and Mac operating systems, software programs need to be developed differently, for both. The software that you can use for recovering deleted files from an SD card on Mac, is 'File Recovery For Mac', developed by Applexsoft. You may download the trial version, that is available for free, but to use the full program, which also works as a hard drive data recovery software, you will need to buy the program, which is priced at USD 99.95. The program is a good investment as it can retrieve deleted files from almost any storage device including an Apple iPod, hard drives, and USB flash drives.
Once you buy and install the program, all you need to do is run it and specify the destination from which you want to recover the data. You will also need to specify a target destination for the recovered files to be copied. With that, your job will be done, in a matter of minutes, depending on the size of the data files. If you only need to recover photos, there is a separate software called 'Photo Recovery for Mac', which you can buy for USD 49.95. To recover files on the Mac hard drive, you can use the inbuilt 'Time Machine' program on Mac OS X Snow Leopard.
For Windows, there is a free software that you can use for recovering deleted files. It is named 'DiskDigger' and it works only on Windows. It can recover deleted audio, video, and text files from any storage device, including memory cards. All you have to do is download the program, install it on your computer, and run it to recover your lost data.
All it takes is the installation of the right software, which can do the job for you. However, in some cases, the deleted data may indeed be lost forever. This fact underlines the need for data backup, which can prevent the loss of data. It is a good idea to create a backup as soon as you have some new data on your SD card.
