Please help - sd card problem

Hello, I was wondering if someone can please help me. I think I have a corrupted SD card. I did some searches on trying to fix it, I found plently of downloads and comments about people being able to fix a corrupted SD card. My problem is, "How can I fix my SD card if it's UNREADABLE?" Did a search on that too, some say it's possible to fix an unreadable card? How? I tried putting it in my 15-1 card reader..."says nothing is there"...tried putting it in my fiance's camcorder..."freezes"...tried to put it in my digital camera..."Card Error"....what do i do from here?!?! Please tell me there's something i can do to revive this card!!! I know some answers would be...buy a new one...i know this, but would like to know if anyone knows anything...anything to fix this card.

Thank you for your time,
Debbie

Oh and when I put it in my 15-1 card reader which is part of my PC and look at My Computer, I can see the drive that I inserted it in flicker and the green light on the card reader turns on as something is in it. But when I double click on the drive in My Computer to read the card, it tells me in insert a disk...but it's in there.

 

Hello...i tried it and the program doesn't see anything in the drive...
