How do you repair damaged SD Card?

I have a 512MB SD…Everything was fine until 1 day, my Kodak C613 could no longer read it and said it needs to be reformatted, I tried reformatting it using the digital camera but it couldnt. I tried using it in my PC and tried to reformat it under Windows VIsta but it only reads "242 MB" when its supposed to be 512mb. I tried it anyway but it still couldnt no matter what even quick or quick format unchecked… I tried downlaoding a format utility and it reads the same 242MB as the size… I was still able to recover most of my lost photos using recovery software but I need to make it back to 512 again. Do you know if my SD card is already damaged?? Help, help please…

i want to buy it, but is it worth the money? What’s the summary of the series and what would you grade it?

my xp pc is running slow, i have taken the unnecessary programs away and cleaned registry. Looks like the only way to get the original performace back is to reinstall windows. Can i reinstall xp without touching programs, i may backup files first but not programs? or any other suggestion to speed up the old pc? Thanks

So every time I try to cut on my laptop it starts but this Start Up repair thing keeps popping up instead of going to my log in screen. It always ask would i like for windows to attempt repairs and I always click yes but it never gets repaired. After going through the same thing 3 or more times it goes to another screen that states "start up repair cannot repair the computer automatically" so I always choose to send the information about the problem. When I come off that screen i choose to always advance view advanced options for system recovery and support. I fill out all the info that they request (country, screen name, & password) and they give me the choices of: start up repair (which i automatically do and it gets me nowhere), system restore (which i do from this point but once i shut down my lap top then use it, shut it down when i’m done, and then cut it back on I have to go through the whole start up repair process over again, windows complete PC restore (idk what a backup image is), windows memory diagnostic tool (did it yesterday and it said there was nothing wrong with my memory), command prompt, and dell factory image restore (if i do this will it erase all my documents and things like music that i have already saved to my computer? seeing that it restores my system software to factory condition)

Please help!!! Idk what I did so hopefully one of you will help me!
