I would talk with Kingston here as your drive should have worked without any problems here. As to saving your data you will need a second Mac connected via Ethernet or ThunderBolt (USB2 is slow) ''back to back'' so your system can be started up in Target mode. Here's how to do to it: [http://support.apple.com/kb/PH13842|OS X Mavericks: Transfer files between two computers using target disk mode], Then you'll need to try Disk Utility to see if you can repair it. If that fails your options here are limited.
