Memory Card Corrupted... any suggesions..?

Hi everyone, I am using Nokia N-70 (still...)

I have a 1gb memory card (MMC mobile card)

While i was downloading a file onto my Memory Card(in Mobile), it automatically stopped working..!

Then i Safely Removed the card, and once again inserted in my mobile,

it says "Memory Card Corrupted"..!

Also, i tried formatting the card through my Mobile... But, the format process did not complete...

In fact, the Format process, didn't start at all..!

Now, when i connected it to my computer(using a Card Reader), it wont detect my Memory Card at all...!

So, unless the card is detected, i cannot format it..

Please suggest me, How can i Format the Card, or make it usable....!

or if u know, any software for Nokia N70, with which i can format the card using my mobile itself..Bcoz as i said, my Computer wont detect it.. So i cannot Format it using my Computer...

or any other method to make it usable would be really helpful....
