Erase Disk

Erase Disk is a Fujitsu Technology Solutions feature embedded in the system firmware (UEFI:
Unified Extensible Firmware Interface), to erase all data from SATA hard disk(s) or SSDs.
This function can be used to delete all data from internal or external hard disks or SSDs
connected via the eSATA port, before the hard disks are discarded or the complete
computer system is disposed of. The function can also be used if hard disks are to be
completely deleted, e.g. before installing a new operating system.
The application can only be selected and run if an administrator/supervisor
password has been assigned (Menu BIOS Setup - Security).
To erase data from SATA hard disks or SSDs, proceed as follows:
► Call the BIOS Setup with the Administrator/Supervisor password.
► To start the application, select Erase Disk (BIOS Setup - Advanced or BIOS
Setup - Security) and set Start after Reboot.
► Then select Save Changes and Exit in the menu Save & Exit / Exit to initiate
a reboot and start Erase Disk.
Because of the reboot, the Erase Disk will be started. You have the option
to interrupt the process during the user selection.
► After the application starts, the Administrator/Supervisor password must
be entered for security reasons.
A dialogue field appears in which a particular, several or all the hard disks can be selected
for deletion. This depends on the number of hard disks in your system.
► Select the hard disk(s) to be deleted. The selected hard disk(s) will be deleted one-by-one.
Erase Disk offers four deletion options, from fast (with one deletion pass) to very
secure (with 35 deletion passes). Depending on the algorithm chosen, the process
can take between ~10 seconds and ~10 minutes per GB:
• Zero Pattern (1 pass)
• German BSI/VSITR (7 passes)
• DoD 5220.22-M ECE (7 passes)
• Guttmann (35 passes)
SSD drives are securely erased with the Enhanced Secure Erase ATA
command integrated in the firmware.
► Select the desired deletion algorithm for the selected hard disks.
