The security lock will be disabled upon successful completion of the secure erase. The first command enables the ATA Security feature and the second one initiates the hardware secure erase which can take anywhere from 20 seconds to several minutes. To use the ATA Secure Erase feature built into the SSD you must issue the following two commands replacing the "sdX" with the correct drive identifier for the SSD. To confirm you are using the correct drive identifier, run this command making sure to substitute the correct drive identifier for the SSD in place of the "sdX" in the following command which should show you the Crucial MX100: sudo hdparm -I /dev/sdX | grep -i model sudo lsblk -o NAME,FSTYPE,LABEL,SIZE,MODEL Run the following command to get the drive ID for your Crucial SSD or you can use the GSmartControl app which is located "Start Menu -> System Tools -> GSmartControl" to get the drive ID. Open a terminal app (the black icon on the bottom left of the Taskbar near the "Start" menu). Option Boot the Knoppix USB drive and select the orange icon labeled "EFI". If this doesn't help, then we could try a hardware secure erase on the SSD, but it is a bit risky to perform when the SSD is connected using USB.Ĭreate a bootable Knoppix Linux USB drive using Etcher (Mac/Windows/Linux). In Disk Utility you may need to click on "View" and select "Show all devices" in order to see the SSD in the left pane of Disk Utility. When you ran DriveDX the drive identifier for the SSD was "/dev/disk2", but it might be different the next time you connect the SSD so double check before running the following command where you replace the "diskN" with the correct drive number: sudo dd if=/dev/zero of=/dev/diskN bs=100m count=10įor example if the drive identifier (or Device Path) for the SSD is "disk2" as shown in the DriveDX report, then the command you will use is: sudo dd if=/dev/zero of=/dev/disk2 bs=100m count=10Īfter this see if you can erase the SSD using Disk Utility. You will need to get the drive identifier for the SSD. The easiest thing is to open the Terminal app and use the command line utility "dd" to erase the beginning part of the SSD so it will appear blank. There is a newer firmware available for this SSD, but it only resolves a security issue when the SSD's hardware encryption features are used.
