Q : How fast will Drive eRazer Ultra erase the data on my drive?

Drive eRazer Ultra can erase modern hard drives at up to 7 GB/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 take longer. Finally, the erase mode plays a role. Quick Erase will generally finish a little faster than Secure Erase.

Q : Will Drive eRazer Ultra work with a Solid State Drive (SSD)?

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.

Longer answer: With SSDs, the host (such as 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. 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 flash 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 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. However, at least one study has shown that some early SSD manufacturers did not correctly implement this portion of the ATA specification. So, while most SSDs will be erased fully by Secure Erase, some may not. If you know that a particular SSD model correctly executes Secure Erase per the ATA spec, these modes can erase the SSD completely. If you’re unsure, you should assume that data fragments could remain.

Q : With what drive capacities is Drive eRazer compatible?

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. In addition, some old drives smaller than 10GB do not follow modern ATA specifications and therefore cannot be erased by DEU.
As for very large drives, there is currently no known limit to how large of a disk Drive eRazer will erase. As of April 2015 Drive eRazer has been tested with up to 6TB hard drives, the largest available. We have no reason to believe Drive eRazer will not continue to work with newer and larger drive sizes as they are released.

Q : Has Drive eRazer Ultra been evaluated by NIST?

NIST (National Institute of Standards and Technology) has evaluated our erasing techniques on a previous model, Drive eRazer Pro. Although our 'Ultra' version (which adds additional features) has not been specifically tested, it employs the same basic techniques used in the tested version. We're therefore confident that the new model would likewise achieve 'expected results' (NIST's equivalent of a passing grade).

Q : What sizes are the labels that Drive eRazer Ultra Prints?

Drive eRazer Ultra can attempt to print one of two different label sizes: 4"x1" or 4"x6", depending upon how it's configured.

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

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." This cable is available from CRU (Part
Number 7380-8000-03). 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 kind of printer should I use with Drive eRazer Ultra?

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 CRU support for up-to-date information about Drive
eRazer Ultra and serial printers.

Q : Why does the USB connector look like USB 3.0 but the documentation says it's USB 2.0?

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 firmware upgrading, rather than for lengthy data transfers. For these two purposes USB 2.0 speed is sufficient.

Q : How does Secure Erase work?

Secure Erase is a feature on nearly all 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 : In Secure Erase Enhanced mode, my drive appeared to erase far too quickly (seconds rather than hours). Did it really get erased that fast?

SEDs (Self Encrypted Drives) feature internal encryption, which is a security feature that scrambles all data on the drive as it is written, and decodes it as it is read back. The encryption engine uses a logical key, usually 128 or 256 bits in length, to perform the encryption/decryption calculations. To quickly render the drive unreadable, some SEDs simply erase and change the value of the key when Secure Erase Enhanced is invoked. Because it no longer has the old key to decode the bits on the drive, the original data is irretrievable and the drive appears to be unformatted. An examination of the drive's contents would show seemingly random data in every sector. Any new data written to the drive would use the new key.

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

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 flow 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.

Q : With what drive capacities is Drive eRazer compatible?

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. In addition, some old drives smaller than 10GB do not follow modern ATA specifications and therefore cannot be erased by DEU.
