MicroSDHC 16Gb corrupted

OK so i tried to copy some files from my 16GB MicroSDHC card from my phone. It began coping, but mid way threw i got a windows error pop up and the sd card stoped working. I plugged it back into my phone and got a message saying “SD card Blank or Missing.” I removed the card and  put it back in the computer, it came up on the computer but it had no memery and after Five minutes it began to melt my card reader. I just wondering if anyone Might know what could have happend or if its fixable.
