micro sd fried?

Hi, I had an htc windows fone which dropped at the shopping centre, it fell three floors before hitting the concrete, the mobile was destroyed so when I went home I removed the sd card in the back, I put it in an adaptor but it won’t work in a digital camera, I bought an sd reader and my laptop just says insert a disk into the drive, it won’t register in my blackberry and I tried it in the dvd player in my car. And it came up bad disk, is there any way I can retreive the files now or have I lost it all, I tried the program made by card recovery and it didn’t fine the disk either and I tried a few others but each time it it says it can’t find a disk in the drive. All advice greatly appreciated.
