Hi 7amzakamel,
The code 27 means the test timed out, which means the test has not been done, the reason for this varies, may be from physical connection, or from OS commands, or even drive controller
Are you connecting this SSD thru USB? If so some SMART commend may not pass through USB interface, if not then maybe there are other issues, have you seen any other problem with functionality of the drive ?
You can always contact our support centers for more detailed troubleshooting to isolate the issue
