Guys my 16Gb SD card just died. I was trying to do a backup so I wanted to remove old one but it didn't allow me saying that card is in read only mode, then i tried to connect it via USB phone said that there are errors and suggested to fix them on PC ( I tried Wind 7 64bit)

It found errors and said that successfully recovered however I was not able to browse card and then it completely disappeared from my computer , N900 also doesn't see, printer says error in memory card...so can you tell me is it really dead? no option to recover? do you know any good software?

Thanks
