The "Self Destruct" feature is a defense against brute force password hack attempts. DataLocker products (Enterprise, DL3 and Sentry) perform this by "zeroizing" all the device’s encryption keys once a pre-set number of failed login attempts is reached. 
Once the encryption key is deleted, the data can not be recovered.  Powering off the unit does NOT reset the unsuccessful password attempts counter. Use this feature with caution.

For Enterprise users:
When activated, after nine unsuccessful password entries the encryption key is deleted rendering all of the data on the drive inaccessible.  
The initiation sequence is: 3 unsuccessful attempts, power down, 3 unsuccessful attempts, power down, 7th unsuccessful attempt and a "Hack Detected" warning message will appear, 8th unsuccessful attempt and warning will appear again, after the 9th unsuccessful attempt the device self-destruct will initiate. 
This feature can be disabled in the "Options" menu which is available immediately after entering your initial password.

For DL3 users:
By default the DL3 allows 10 failed password attempts before it self-destructs. The user can set the counter to 10-30 attempts through the setup menu. After the drive has self-destructed, the encryption key is deleted rendering all of the data on the drive inaccessible and the drive returns to its default state; the password is 000000.
If the attempt counter is set for 10 attempts, the self-destruct sequence is 5 unsuccessful attempts, power down, 7th unsuccessful attempt and a "Hack Detected" warning message will appear, 8th and 9th unsuccessful attempt and warning will appear again, after the 10th unsuccessful attempt the device will self-destruct.

For Sentry users:
By default, the Sentry gives you 20 failed password attempts before it self-destructs. After the drive has self-destructed, it erases the encryption key rendering all data inaccessible and the drive returns to its default state, prompting you to create a new password.

For RFID users: 
By default, the DL3  gives you 30 attempts to enter the incorrect "Input Tag" before it initiates its self destruct mode and wipes the drive. This deletes the encryption key rendering  all data inaccessible and returns the drive back to its default state and settings. After you input the incorrect "input key" 5 times the DataLocker powers down. You will need to disconnect the drive and reconnect it again, where you will get 5 more attempts, so on and so forth until you reach 29th failed attempt when it will display a message warning that if you enter the incorrect "input key" again, the drive will self destruct. Once you have input the 30th incorrect key the drive will power down and output a long beep, which is prompting you to disconnect the drive again. Once you disconnect and connect the drive again you will notice that you will be prompted to initialize the drive, and set up a new password again.
