Hrm, try power cycling your SSD.
1. Find a computer that you can use for approximately 1 hour. We recommend that you try to perform this procedure on a desktop computer because it allows you to only connect the SATA power connection. This will improve the odds of the power cycle being successful. A USB enclosure with an external power source will also work.
2. Once you have the drive connected and sitting idle for a desktop it is simply powering the computer and waiting. The computer will need to stay powered on for 20 min, and it is recommended that you don't use the computer during this process.
3. Power the computer down and disconnect the drive for 30 seconds.
4. Repeat steps 2 and 3 one more time.
5. Reconnect the drive normally, and boot the computer to your operating system.
6. Update your firmware, if you are not already at the latest on your drive.
After doing this, please let us know the results.
