Memory cards are also called as digital film, which are used to store files. Memory cards are available in different size and capacities. Most of the portable electronic devices use different types of memory cards like SD, XD, and MMC etc. Earlier, older cameras were using smart media(SM) cards, which are still available but, these memory cards can store only less amount of data therefore they are replaced by XD and SD cards. JPEG and JPG are the two file formats used for saving photos in memory cards. JPG extension is used in Windows platform whereas JPEG is used in Mac. In some digital cameras JPEG file format is by default made use for saving pictures. Generally, memory cards are used to store pictures in digital cameras. Although the memory cards have several advantages over other type of storage devices, they are more prone to data loss during photo transfer from memory card to system. You can easily recover JPG files, using some memory card recovery software or photo recovery software.
The most common data loss scenarios are virus attacks, accidentally formatting the memory card and accidentally deleting contents of memory cards. Formatting is a process of setting up a new file system by erasing the existing content. Sometimes, while previewing photos from digital camera if you press format option then it will erase complete data present on digital camera, which may result in data loss. But, it’s not a permanent loss. When you format a memory card, it rebuilds the new file system by erasing the existing contents. So, you may not be able to access the data because, the allocation information of that data is deleted. But, the actual contents are still present on the memory card until new data overwrites the free space.
Sometimes, digital camera’s memory cards get corrupted due to improper formatting methods or virus attack. So, to avoid corruption of memory card use proper methods to format memory card. To retrieve lost or deleted data, do not save any new data over affected memory cards. You can use memory card recovery software to recover lost, deleted and corrupted files. Try to use read-only recovery software to avoid permanent data loss from memory cards.
