1. Installation Steps

a. Attach the protective metal drive plate to, your 3.5” hard drive (This step is

optional). The purpose of the bottom pate is to provide protection to your

plate drive electronics and air heat dissipation.

b. If erasing an IDE/PATA drive, configure the jumpers on the rear of the drive.

The drive must be set to the “Master” setting. Consult the instructions for your

drive (some drives display configuration information on the drive’s label).

c. Ensure that the 4Secure erase power switch is in the OFF (O) position.

d. Connect 4Secure erase to the drive (or adapter), using either the IDE ribbon

cable for IDE drives, or the SATA data/power cable for SATA drives.

e. If using an adapter, connect the drive to the adapter.

f. Attach the power cable to the 4Secure erase and to the drive. For SATA

drives, the power cable and data cable are combined into a single SATA

drive interface.

g. Plug the AC adapter into the 4Secure erase.

h. Turn on the power switch. The connected drive will power up and the 4Secure

erase main menu will appear on the LCD screen.

2. Using the LCD Interface and Menu

Use the LCD and 4-button navigation interface to start erasing, adjust settings,

view information about the drive and dock, or check on operational status. On

the 4-button navigation interface, up and down allow scrolling through options,

while right selects and left goes to the previous screen.

3. Menu Structure

(See the full User Manual for additional details at www.4-secure.com)

4Secure erase menu consists of the following screens:

• Start Erasing: Begins the erasure process using current settings. (By default,

HMG IS5 Erase mode is used).

• Review Settings: Allows the user to view and change settings such as the

erase type, HPA/DCO handling, verification level and printer output type. The

user may also reset all settings to their original factory default values.

• View Drive Info: Displays information about the 4Secure erase product.

(Device name, unique ID number, firmware version).

• Operational Status: During erasure, status messages are displayed on the

LCD. Examples are shown below:

• Error Indication: If 4Secure erase encounters any errors, a brief explanatory

message will display. Examples are shown below:

4. Label Printer Output

4Secure erase features a DB9 null-modern serial connection for the purpose

of connecting a label printer. This will allow 4Secure erase to print a 4” x 6.25”

(101mm x 159mm) label recording details of an erase process upon completion.

The label can then be affixed to the drive, or to a DriveBoxTM anti-static storage

case. You may also print a label as a test without an erasure process.

5. Reporter App

This application can be installed on any Windows based PC or Laptop. It actively

monitors for all erase communication and on receipt of each disk erasure

notification stores the output file in a user defined location.

Optimal Performance Instruction

Q: How does the Secure Erase work?

The 4Secure erase benefits from several user configurable settings that can

affect the speed in which the wiping process takes. For optimal performance in

both IAS5 wiping and non IAS5 compliant wiping please follow the guidelines

below.

IAS5 Compliant wiping:

The 4Secure erase defaults to a “MEDIUM” verification, this is the level of

checking that takes place following an erase of a hard disk drive.

Verification Option

Verification Level

MINIMAL

<1%

MEDIUM

HIGH

10%

COMPLETE

100%

To reduce the overall process time, you can change the verification setting* to

“MINIMAL”.

*Consultation with the senior risk owner should be conducted prior to altering the default verification

level for the HMG IS5 ERASE mode.

Please follow the guide below to review and or change your settings:

1. Follow the Quick Start Guide to power up the 4Secure erase and mount the

drive. Then you can review and change the settings.

2. 4Secure defaults to the “HMG IS5 ERASE”.

either “MINIMAL”, “HIGH” or “COMPLETE”.

9. Use the “Up” and “Down” keys on the keypad to scroll through the different

verifications.

10. For reduced erase times, select “MINIMAL” and press “ENTER”.

11. The display will show “MINIMAL”, “MAKE DEFAULT?”. Selecting “ENTER”

will change the default setting to “MINIMAL” verification.

12. You will then return back to the “VERIFICATION” menu option.

13. Pressing the “Back” key twice will take you to the “START ERASING” menu

option.

14. Select “ENTER” on the keypad, the erase will display “WILL ERASE ALL

DATA”. Press “ENTER”, and the unit will commence the erase processes.

Frequently Asked Questions (FAQ)

Q: How does the Secure Erase work?

A: Secure Erase is a feature on many modern hard drives (greater than 15GB).

This feature is activated by a low-level command to the drive and causes the

drive to erase itself using methods developed by the drive manufacturers in

conjunction with the US NSA. To protect against malware attacks, operating

systems such as Windows and Mac OS (and software written for these operating

systems) cannot send this command, but 4Secure erase can.

Secure Erase sequentially overwrites the data on the drive, similar to 4Secure

erase’s other erase modes. However, Secure Erase better handles data on

“bad blocks” (single pass may stop and report an error at a bad block).

Secure Erase is implemented on most drives that were manufactured in 2001

or later; however, an estimated time for completion was not added until later.

Some drives therefore support Secure Erase but will not be given an estimated

completion time.

Q: How fast will the 4Secure erase, erase data on my drive?

A: The 4Secure erase can erase modern hard drives at up to 7GB/minute or

more. The erasure time depends on several factors. Older drives will generally

take longer than newer ones. Higher levels of verification will not affect the time

spent erasing but will make the total process takes longer. Finally, the erase

mode plays a role. Quick erase will generally finish a little faster than Secure

Erase.

Q: With what drive capacities is 4Secure erase compatible?

A: 4Secure erase cannot erase extremely small drives or media that are less

than 10,000 sectors. Assuming a 512-byte sector size, 10,000 sectors is less

than 5GB. There is currently no known limit to how large of a disk 4Secure

erase can erase. As of September 2011, 4Secure erase has been tested with

up to 6TB hard drives. We have no reason to believe 4Secure erase will not

continue to work with newer and larger drive sizes as they are released.

Q: Do I have to jumper my IDE-drive to a particular setting?

A: 4Secure erase cannot erase extremely small drives or media that are less

than 10,000 sectors. Assuming a 512-byte sector size, 10,000 sectors is less

than 5GB. There is currently no known limit to how large of a disk 4Secure

erase will erase. As of September 2011, 4Secure erase has been tested with

up to 6TB hard drives. We have no reason to believe 4Secure erase will not

continue to work with newer and larger drive sizes as they are released.

Q: What kind of printer should I use with the 4Secure erase?

A: 4Secure erase was tested primarily with Zebra brand printers compatible

with ZPL II formatted text (often indicated by -Z at the end of the model number).

During development we made every effort to make this feature as compatible

as possible, but no list of compatible printers is currently being published. If

choosing a new printer, the Zebra product line is a good starting point. Please

visit www.4secure-erase.com, under resources for a list of compatible Zebra

printers.

Q: What kind of cable do I need for the Printer Port?

A: The printer port is a standard 9-pin serial RS-232 port. 4Secure erase

requires a male end and most printers also require a male end. If you need to

source a new cable, what you need is probably a “Male to Male RS-232 (DB9)

Null Modern Serial cable”.

Q: Can I output the erasure results to a PC?

A: Yes. When using a DB9 null-modern serial cable (with appropriate serial or

USB connector) and after installing the 4Secure Erase Reporter application,

you can connect and output to any PC (Windows OS).

CERTIFICATION OF HARD DRIVE DISPOSITION

Q: What information is included in each label that 4Secure erase prints?

A: See the example below:

Q: Why does the USB connector look like USB 3.0, but the

documentation says it’s USB 2.0?

A: 4Secure erase uses a USB 3.0 style connector because it shares a form

factor and many parts with another product; however, the controlled chip that

drives 4Secure erase’s USB connection supports USB 2.0 only. The port can

be used with either USB 2.0 or 3.0 type cables and with either USB 2.0 or 3.0

hosts, but it will operate at USB 2.0 speed. The intended purposes of the port

are the previewing of a drive and firmware upgrading, rather than for lengthy

data transfers. For these two purposes USB 2.0 speed is sufficient.

Q: Can I switch drives or attach a hard drive when the unit is turned on?

A: This is not recommended because it could cause an electrical short that

could damage the 4Secure erase or the drive.

Q: Will 4Secure erase work with a Solid-State Drive (SSD)?

A: Short answer: SSDs erased by 4Secure erase in any mode would be safe

from casual data retrieval attempts, but for very sensitive data the only way to

guarantee security is to physically destroy the drive.

Longer Answer: The SSDs controller may instead remap that physical sector to

a new logical sector, leaving the data intact but accessible. Even a full overwrite

of an SSD may therefore not result in a fully wiped drive; however, the data

remaining on the drive would not be accessible via normal means.

Recovering such data would require removing the actual flash chips from the

SSDs circuit board and accessing them with special equipment and software

tools. Secure Erase modes offer the best chance of fully erasing an SSD

because they use the drives built in erasing function. Secure Erase is defined

by the ATA specification and requires drives to fully erase all user accessible

data areas when the command is received. The enhanced version also erases

any data within HPA or DCO areas.

At least one study has shown that some SSD manufacturers did not correctly

follow at least this portion of the ATA specification. So, while some SSDs will

be erased fully by Secure Erase, others may not. If you know that a particular

SSD model correctly implements Secure Erase modes per the ATA spec, these

modes can erase the SSD completely. If you are unsure, you should always

assume that data fragments could remain.
