2. Setup

a) Attach protective metal drive plate to your 3.5” hard drive. (This step is optional.) The purpose of the bottom plate is to provide protection to your drive electronics and aid heat dissipation.

b) If erasing an IDE/PATA drive, congure the

jumpers on the rear of the drive. The drive must be set to the Master setting. Consult the instructions or your drive (some drives display

conguration information on the drive’s label).

c) Ensure that the Drive eRazer’s power switch is in

the OFF (0) position. d) Connect Drive eRazer 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 Drive eRazer Ultra 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 Drive eRazer Ultra.

h) Turn on the power switch. The connected drive will power up and Drive eRazer Ultra main menu will appear on the LCD screen

WARNING: Ensure that Drive eRazer Ultra’s power

switch is in the OFF (0) position before connecting a drive.

3. Menu Structure/Usage of Drive eRazer Ultra

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 ENTER selects and BACK goes back to the previous screen.

this function overwrites all addressable areas using zeroes. HPA or DCO areas are excluded per the spec, but Drive eRazer Ultra will unhide such areas prior to initiating Secure Erase if the user has changed the HPA/DCO behavior in the Settings menu. Secure Erase is better able to handle bad blocks compared to other erase methods.

4. Frequently Asked Questions (FAQ)

Q: How does 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 NSA. To protect against malware attacks, operating systems such as Windows and Mac OS (and software applications written for these operating systems) cannot send this command, but Drive eRazer Ultra can.

Secure Erase sequentially overwrites the data on the drive,

similar to Drive eRazer’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 give an estimated completion time.

Q: Do I have to jumper my IDE drive to a particular setting? A: We recommend that you jumper your IDE/PATA hard drives

to a MASTER setting. Some hard drives have two different MASTER settings: one for when there is a SLAVE drive present and one for when there is NO SLAVE drive present. Choose the setting for NO SLAVE present. There may be some drives that will not work with either of these settings. The next choice is CABLE SELECT. If this does not work, try using NO jumpers. This may be the same as MASTER with NO SLAVE present.

Q: What kind of printer should I use with Drive eRazer Ultra? A: Drive eRazer Ultra 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. Feel free to contact WiebeTech for up-to-date information about Drive eRazer Ultra and serial 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.

Drive eRazer Ultra 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

Modem Serial cable.” Check your printer’s documentation regarding serial cable types. Connecting it to a computer’s

serial port is possible with a “Male to Female RS-232 (DB9) Null modem serial cable”.

Q: What sizes are the labels that Drive eRazer Ultra prints? A: Drive eRazer Ultra can print one of two different label sizes:

4”x1” or 4”x6”, depending upon how it’s congured.

Q: How fast will Drive eRazer Ultra erase the data on my drive? A: Drive eRazer Ultra 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 verication will not affect the time spent

erasing, but will make the total process take longer. Finally,

the erase mode plays a role. Quick Erase will generally nish

a little faster than Secure Erase.

Q: With what drive capacities is Drive eRazer compatible? A: Drive eRazer 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 5MB. There is currently no known limit to how large of a disk Drive eRazer will erase. As of September 2011 Drive eRazer has been tested with up to 3TB hard drives. We have no reason to believe Drive eRazer will not continue to work with newer and larger drive sizes as they are released.

Q: What information is included on each label that Drive eRazer Ultra prints?

A: Below are examples of the two types of labels that Drive Eraser Ultra generates.

4” x 1” label

Page 8

(continued from previous page)

4” x 6” label

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

documentation says it’s USB 2.0?

A: Drive eRazer Ultra uses a USB 3.0 style connector because it shares a form factor and many parts with another product.

However, the controller chip that drives DEU’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 rmware upgrading,

rather than for lengthy data transfers. For these two purposes

USB 2.0 speed is sufcient.

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 Drive eRazer ultra or the drive.

Q: Will Drive eRazer Ultra work with a Solid State Drive (SSD)? A: Short answer: SSDs erased by DEU 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.

The SSD’s controller may instead remap that physical

sector to a new logical sector, leaving the data intact but inaccessible. Even a full overwrite of a 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 ash chips from the SSD’s 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 drive’s built-in erasing function. Secure Erase is dened by the ATA specication 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. However, at least one study has shown that some SSD manufacturers did not correctly

follow at least this portion of the ATA specication. 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’re unsure, you

should assume that data fragments could remain.

Q: My Drive eRazer Ultra shows “WRITE CMD ERROR” on the LCD and the erase has stopped progressing. What do I do next?

A: This message means that the drive reported an error when attempting to execute a write command sent to it by DEU. Several things can cause such an error, such as a bad block on the drive, or a poor physical connection between DEU and the drive. It may occur if the drive or dock is moved or bumped during the erase process. This is an unrecoverable error (indicated by the lighting of the Red “Error” LED).

The next step is to turn off DEU’s power. If you like, you can

turn DEU back on and attempt to erase the drive again. A bad block is not always 100% bad, so sometimes a block that fails to be overwritten on one attempt will succeed on the next try. Make sure the cables connecting the drive and DEU are fully seated, and do not attempt to move the drive, DEU, or cables during the erase process. Make sure the drive has

good air ow around it to avoid any possible heat issues. If

you continue to see this error message on the drive, the next thing to try is changing to Secure Erase Enhanced mode. This

mode doesn’t use write commands; rather, it issues a single

command to the drive that causes the drive to erase itself. This mode handles bad blocks better than modes based on write commands. If none of these remedies work, the only way to ensure there are no recoverable data remaining on the drive is to physically destroy it.

Longer answer: With SSDs, the host (such a computer or Drive eRazer) does not have direct access to the sectors on the drive. There is therefore no way to guarantee that a command to erase a given sector will actually erase that sector.

Q: My department requires 100% verication of erasure. Does

Tested to comply

with FCC sta ndards

the “high” option verify 100% of the drive? A: No, although the “high” checks a large number of sectors of

the drive, performing 100% verication would require a much

greater amount of time than the erasure process itself. For this reason, and for the security of having an independent tool, we

recommend using a 3rd party tool for 100% verication.

Many organizations actually require that the erase tool and

the verication tool be separate products.

The Australian Government Information Security Manual, November 2010, states that “Verifying the sanitisation of media with a different product to the one conducting the sanitisation process provides an independent level of assurance that the sanitisation process was conducted correctly” (161).

If it satises your department’s requirements, you could use

a hex editor, such as HxD, to visually inspect the contents of the drive to verify that it was erased.
