I bought a Sandisk MiniSD, 512mb, to use in my LG VX8100 Mp3 phone. I used it for now I guess it has been 2 and a half months. I have put movies and mp3's on the card to listen/watch them on my phone. (while i am typing this I am remembering more so bear with me).
So today I listened to the songs, and then took the card out for a second to show someone (I have taken it out before, no big deal, I do it all the time to put it in my card reader to transfer files to it). I put the card back in my phone and then suddenly it does not work, it says that there are no songs on the card. I get home and put it in my memory card reader, and it does not even register. I think the card is dead. My questions are:
What type of things can cause it to fail or for a device to not be able to read it? (static electricity, smudges on the metal parts, etc?)
When I was listening to Mp3's on the phone right before it died it kept skipping a bit, but I ignored it because it has done that before when I have been in the car and go over bumps, or turn the headphone jack when it is plugged in. But maybe it should not do that, has it been defective all along? Also while typing this I am thinking it is possible (but doubtful) my phone killed it (see next question)
Before it stopped working I tried to listen to music after putting the card back in, and the card worked and everything, but no sound came out of my Phone's speakers, only the headphones (not even the regular non mp3 sound like the phones beeps), so I turned the phone off and then turned it back on and then the sound worked but thats when it started to not recognize the card. Is it possible that my phone was acting up and killed it or something?
It has a 5 year limited warrenty, and I meet all of the criteria to get the warrenty (I was using it in an approved device properly) but I do not have the original packaging, I either lost it or threw it out. I also probably do not have the receipt, but I have the case that it came in. Do I need that? I only have the packaging of my 256mb mini SD card that still works.
Any help or information that you can provide would be greatly appreciated! Thanks a lot for your time 
(I will add more backroung info if I think of any, I might also try howardforums to see if it has happened to anyone else, SanDisk's site gives me nothing)
