The
"Secure Erase" page (tab) is only displayed when running on WindowsPE. It
is not displayed when executed on Windows (8, 10, 11, Server, etc.).
Secure Erase/ Sanitize
Performs Secure Erase/Sanitize processing on supported disks. Please see "Secure
erase/ Sanitize" for the details of the process.
Warning! About "Secure Erase" of ATA drives |
Never interrupt Secure Erase process of
ATA drives!
When performing Secure Erase on ATA
drives (including SATA), according to Microsoft specifications,
"AutoATAWindowsString12345678901" is registered as the HDD password
(user password) before the process is executed.
If the secure erase
is successfully completed, the password will also be erased and you can use
the disk drive as usual. However, if it is interrupted midway (power
off, etc.), the HDD password will remain on the drive and the drive will be
password-locked. You will not be able to use it again, It becomes
inaccessible.
If the HDD password is enabled, you will be asked to
enter the password when you turn on the PC, and if the password does not
match, you may not be able to boot or access the HDD. In that case, you may
be able to remove the password by using the above password in the HDD
password section of the PC's BIOS settings. But if the PC performs its own
conversion of input values, in that case, you may not be able to cancel the
password
How to remove HDD password ・Cancel it in the PC's BIOS
settings. ・If the PC can start, perform the Secure Erase using this
program (gppro4.exe) again. ・If the above is not possible, remove the
drive from the PC, connect it to a PC that can boot even if there is an HDD
password, and remove the password. ・If
the drive cannot be removed from a laptop PC, etc., it may become unusable.
Due to these problems, please be very careful when
performing Secure Erase of ATA. |
Below, only the parts that differ from "Erase Disk drive"
are described in detail.
* If you format the disk again, you can use the disk again.
Select Disk to erase
Only processable(SecureErase/Sanitize) disk drives are listed. Select the disk
drive (physical drive) to erase.
Disk information
Choose "erase Disk" and a select disk to display information about the disk.
Also, click on the "Secure Erase" section to display information about secure
erase. Click "Disk Information" to return to normal disk information
display.
Erase method, options
Select the erasing method and processing option.
[Secure Erase](1time)(sec)
Only "Secure Erase"/"Sanitize" process
is performed.
1st time: Secure Erase/Sanitize
[Secure Erase](2times)(sec-00)
Perform "Secure Erase"/"Sanitize" process and then write [00] to the whole
disk drive. 2nd process is normal write process.
1st time: Secure Erase/Sanitize
2nd time: Write 00 (hexary) / 00000000
(binary)
[Secure Erase](3times)(sec-random-00)
Perform "Secure Erase"/"Sanitize" process and then write values to the whole
disk drive as follows. 2nd, 3rd process are normal write processes.
1st time:
Secure Erase/Sanitize
2nd time: Write a random value 3rd time: Write
00 (hexary) / 00000000 (binary)
Secure Erase Method
Normally, you can leave it as "-Auto-". The process is executed using the
most secure method among all executable processes. You can also choose any
method.
Only methods supported by the disk drive will be displayed as
options.
Processing priority for "-Auto-"
ATA drive Sanitize (block erase) Sanitize (over write) Sanitize
(crypto) Secure Erase (enhanced) Secure Erase
NVMe drive Sanitize (block erase)
Sanitize (over write) Sanitize (crypto) Secure Erase
However, if
Sanitize (crypto) and Sanitize (block erase)/Sanitize (over write) are
supported, Sanitize (crypto)+Sanitize (block erase) Sanitize
(crypto)+Sanitize(over write) is execute in combination.
Verify after erase
After the erasing process is completed, read the whole disk and verify that
all sectors have been erased. This process is normal read process.
Stop when error
If a write error tf a write error to the disk occurs in the middle, you can choose to interrupt
the process or ignore it and continue. If you ignore it and continue, the
number of errors is counted. Error counts are for normal read/write
process only.
Confirm
It is provided for confirmation so that it will not work even if you
accidentally press the "execute ERASE" button. Please enter "YES" ("yes" is
also possible).
execute ERASE
Press this button to start the process.
Interrupt
You cannot interrupt during the secure erase step.
For normal read/write process, you can interrupt the process with the "Interrupt" button at the bottom right.
Close
Click the "Close" button to close the Report screen.
