![]() supported: enhanced erase : If displayed, it supports Enhanced Secure Erase.locked: Whether SSD is locked with password or not.frozen: Whether the SSD is protected from running Secure Erase.enabled: Whether the security function of the SSD is turned on.Notice the "Security" at the end of the above, and the meaning of each item is: ![]() Used: unknown (minor revision code 0x0110 )Ģmin for SECURITY ERASE UNIT. Transport: Serial, ATA8-AST, SATA 1.0a, SATA II Extensions, SATA Rev 2.5, SATA Rev 2.6, SATA Rev 3.0 Next, execute the following command to check the status of the SSD. Run ls -l /dev/sd* in the terminal and check the device file of the target SSD, and proceed as if it was /dev/sdb below. Preparationįirst, mount the SSD directly to the motherboard using a SATA cable without using a conversion terminal such as USB-SATA. Also, in the case of SSDs that support Enhanced Secure Erase 3, it is possible to erase all blocks after de-leveling. When the execution instruction of Secure Erase comes, the SSD erases this mapping table so that it forgets how to read the data stored in the flash memory and makes it impossible to decipher. Inside the controller of the SSD is a mapping table that stores the correspondence of "which data was recorded at which position". Secure Erase is a function built into SSDs and is used by calling it from the outside. However, since SSD handles data in blocks unit, the mechanism is different from HDD, and since it is equipped with technology 2 to improve the life of SSD called wear leveling, it can not be overwritten correctly by the above method.įor this reason, recent SSDs are equipped with Secure Erase, a mechanism for completely erasing data by SSD itself.
