Most of the Digital Portable Devices have a low internal memmory and have to depend on expandable memmory resources like the memmory cards. Such memmory cards are very delicate ( not physically ! ) and can become useless easily. But a little care can keep them with u for a long time.
A memory card like a SD card or a multimedia card can get corrupted if its file system is distroyed. Then it cannot be used any further. Special care has to be taken while file system is open and andy write process is occuring. Make sure u do the following.
* Do not switch off your camera ( Lets take this as an example ) while a new picture is being written to the card.
* Do not eject the card while your cam is still on.
* Do not move the files to a computer using the windows explorer. Use the associated software. If you are using windows explorer copy the files instead of moving them.
* Do not format your card using windows explorer. Format it using ur cam.
* Format the card at regular intervals. Do not use it for a long time ( like 6 months ) without a format.
* Do not bend the Card or expose to heat or extremes of weather.
Its aways the little things that make big changes.
