What is wrong with the flash memory card?

i bought this flash memory card a couple of weeks back. i used it a couple of times it was fine but since yesterday, there's something wrong with it. i don't know what though.


when u put data on it, u unplug it, the next time u wanna use it, it just doesn't open. and it says memory card needs to be formatted everytime. and well, when u format it, u lose the data of course.


any ideas what it might be?








(it couldn't be any physical damage coz it's been all safe all this time. could it be a virus or sth?)

What is wrong with the flash memory card?
This is because your memory card may be affected with some virus (Unknown %26amp; unseen). It will be there in the main directories. Format and use some trustable antivirus software to clear the virus. or else... be very careful in using your mobile when connected with bluetoth and internet. do not accept any files from others so easily till you trust.
Reply:did you use "remove hardware safely" feature when you removed your flash memory? If not this could be one factor. A lot of these things crashes especially the cheap and unknown brands. Aside from physical damage you might have damage it electromagnetically (this happens when the flash card is exposed to EMDs - electromagnetic discharge or ESDs - Electrostatic discharges, which you get from magnets, carpets or by placing it near a high voltage appliances like your tv or monitor).


on the case of a virus you can easily remove it by formatting the flash memory, so i'm sure its not.
