See the procedure below - it's likely you'll be asked to do this by the manufacturer anyway
In most cases, your SSD can be returned to normal operating condition by completing a power cycle. The process will take approximately one hour.
We recommend you perform this procedure on a desktop computer because it allows you to only connect the SATA power connection, which improves the odds of the power cycle being successful. However, a USB enclosure with an external power source will also work. Apple and Windows desktop users follow the same steps.
1. Once you have the drive connected (if possible WITHOUT the data connection) and sitting idle, simply power on the computer and wait for 20 minutes. We recommend that you don't use the computer during this process.
2. Power the computer down and disconnect the drive for 30 seconds.
3. Repeat steps 1 and 2 one more time.
4. Reconnect the drive normally, and boot the computer to your operating system.
5. If the latest firmware is has not been updated to your drive, do so.
If it still doesn't work after a cold reset then it's a failure and it'll be replaced under warranty.
