Memory card is a solid state electronic flash memory data storage device used for storing digital information. They are commonly used in many electronic gadgets like MP3 players, laptops, digital cameras, mobile phones and video game consoles. They are small, re-recordable and can retain the data even when the power is off. Different types of memory cards are available in market like SD, XD, CF, MMC and many more. Each and every memory card type is equipped with advanced features to entertain users and they provide user friendly interface. Memory cards can store different types of files like audio, video, images, movies. Memory cards are easy to handle but they are also easily prone to data loss under certain circumstances in such cases use memory card recovery software in order to restore important files from memory card. This application can also be used torecover deleted files on Mac OS X based computer.
Under following circumstances files get deleted from memory card:
- Human errors: Human beings are the main reason for deletion of data from memory card. Since memory card data storage capacity is limited you may tend to delete some unimportant files from memory card to make space for new data. While deleting unimportant ones you may accidentally delete important files. Sometimes it may happen that you accidentally press the “Delete All” button provided in many media devices while performing some other actions.
- Third party applications: Virus infects and damages the memory card files severely. Since they can replicate themselves at a faster rate in a small memory space, they spread faster and corrupt the memory cards. Virus usually spread to the memory card when you connect the memory card to virus infected system for data transfer. To get rid of virus you may install anti virus on system, connect and scan the memory card. While scanning the memory card with the help of anti virus program, if the program sense that the file is severely corrupted by virus then it deletes the file from memory card.
- Accidental Formatting: Sometimes while formatting any other volumes of the computer you may accidentally click on memory card connected to the Mac computer and format it. There is also chance of accidentally formatting the memory card by unknowingly choosing the “Format” option provided in most of the media devices. Whatever may be the reason for formatting, it not only deletes all the files and folders from memory card, it completely resets memory card and creates a new file system.
When you delete the files from memory card they are not permanently removed from memory space of card instead file pointers pointing to the physical location of that file will be deleted. The deleted files remain intact until you overwrite it with new data. So once you sense that the important files are deleted from memory card stop performing further data saving operations on memory card. Remove the card from the media device and connect it to the Mac OS X machine and employ memory card recovery tool to undelete files. This tool is equipped with advanced built in algorithm to retrieve data from missing/ deleted Mac volumes. It can also recover deleted files from SD card and other memory cards like XD, CF and MMC. For SD card recovery you can make a visit to http://www.undeleteosx.com/sd-card.html page. It retrieves files from HFS+, HFSX, FAT16 and FAT32 partitions/volumes. You can use this application to restore files from hard drives, Memory sticks, Fire Wire drives, iPods and USB external drives. Through scanning of the Mac volumes is performed by this tool to recover data from inaccessible volumes. This reliable software can also be used to undelete files on Mac Lion and from other Mac operating systems versions like Leopard and Snow Leopard. You can easily locate required file in recovered list using fast built in “Find Tool” , since it preserves original file names after retrieval and provides preview of retrieved files in Mac finder styled interface before saving them. Use this out standing application to recover Mac OS X photos of different formats like GIF, JPEG, PNG, TIFF, JPG etc. For More on photo recovery navigate to the given link
