Did you assign it a drive letter when you formatted it? If you did and your MPC still doesn't recognize the drive, try partitioning it into 2 smaller partitions of equal size and see if that works. If it doesn't, then perhaps try another drive that is known to work and see if your MPC sees that one. It's also possible there is an actual hardware problem with your SSD connection as well - check to make sure you've got it plugged in correctly and it hasn't become unconnected. Sometime if you wedge them in, it can wiggle out of the SATA port.
