Secure Erasing Disk Drives
When you perform a secure erase on a disk drive, all data on that disk drive is completely and
irretrievably eradicated. Secure erase performs three distinct writing passes to the disk drive
being erased—it does not just write zeros.
Performing a secure erase takes up to six times longer than clearing (or zeroing) a disk drive.
You may want to perform a secure erase only on disk drives that contain confidential or
classified information.
Note:
To erase (or zero) a disk drive with non-classified information, you may choose to
format
it (see
page 90
) instead, or
clear
it using ICP Storage Manager—both options take much less
time than the secure erase option.
To begin a secure erase, select
Secure Erase
from the main ACU menu, then select
Y
(yes). To
return to the main ACU menu once the secure erase has begun, press
Esc
.
The selected disk drive(s) cannot be used until the erase is complete.
Stopping a Secure Erase
To stop a secure erase in progress:
1
In the main ACU window, select
Secure Erase
.
2
Select the disk drive being secure erased, then press
Ctrl+Q
.
The secure erase stops and the ACU returns to its main window.
