Erase Disk
Erase Disk is a solution that is integrated into the firmware of the FUJITSU C ompute r
(UEFI: Unified Extensible Firmware Interface), to delete all the data from a hard
disk or a solid state drive (SSD) memory module.
This function can be use d to permanently delete all data from hard disks or SSD memory
modules, before they are discarded or the complete computer system is disposed of.
The function can also be used if hard disks/SSD memory modules must be completely
deleted, e.g. before installing a new operating system.
The application c an only be selected and run if an administrator/supervisor
password has been assigned (Menu BIOS Setup - Security).
Proceed as follows to d
elete data from hard disks/SSD memory modules:
► Call the BIO S Setup wi
th the Administrator/Supervisor password.
► To start the application, select Erase Disk (BIOS Setup - Advanced or BIOS
Setup - Security) and set St art after R eboot.
► Then select Save Ch
anges and Exit in the menu Save & Exit / Exit to initiate
a reboot and start E
rase Disk.
Because of the reb
oot, 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/memory
modules can be selected for deletion. This de pends on the n umber of hard
disks/SSD storage modules in your system.
► Select the hard disk(s)/SSD memory modules to be deleted. The selected hard
disk(s)/SSD memory modules 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 G B:
• Zero Pattern (1 pass)
• German BSI/VSITR (7 passes)
• DoD 5220.22-M ECE (7 passes)
• Guttmann (35 passes)
SSD dri
ves are securely erased with the Enhanced Secure Erase ATA
comma
nd integra ted in the firmware.
► Select th e desired deletion algorithm for the selected hard disks/SSD memory modules.
