The primary use for memory cards is as a high volume storage media for digital cameras. Memory cards have many types depending upon their size and format. But a few more popular types are smart media, SD and XD picture cards. Almost all of these are formatted in the Microsoft FAT system. When attempting memory card recovery there are a few simple tips to be aware of. The first as with any data recovery situation is never load more information onto that card in the form of new digital pictures until you have successfully recovered all of your old files.
Another important tip is that just because you have downloaded the files from a memory card onto your computer you should never assume that file transfer when successfully. Digital photographs are notorious for having missing parts due to partial transfer of data. To recover memory card files that have been lost due to accidental deletion or poor transfer you will need a digital media recovery program.
