Most of the digital cameras in use today, make use of a flash memory card, for storage of the pictures taken using the camera. The flash memory cards come in different capacities, with the memory capacity ranging from a few Megabytes to a few Gigabytes. The memory card is no doubt an extremely useful storage device, but if not handled with care, it might create some trouble for the user.
The most common reason, for loss of photos from a flash memory card, occurs when the memory card is unplugged from the PC in an improper manner. In such situations, the user ends up pulling out the memory card from the card reader, without disconnecting the device correctly.
