WD Introduced its New My Book and My Passport External Hard Drives with USB 3.0 Connectivity

Oct. 5, 2010 – WD today introduced its new My Passport® Essential™ portable hard drive, My Passport® Essential™ SE portable hard drive, and My Book® Essential external hard drive. All three drive families come in a variety of capacities and offer lightning-fast USB 3.0 connectivity. Highest industry capacity is another key feature for the My Book Essential drive, which is now available in 3 TB capacity, in addition to 1 and 2 TB capacities. Equipped with WD SmartWare™ visual backup software for automatic, continuous backup, these drives provide users the extra space they need to store or back up all of their digital memories, such as high-resolution photos and videos, along with music and other critical files, all in one place.

The drives not only take advantage of the latest blazing-fast USB 3.0 technology, but are also fully compatible with USB 2.0 connections for those who have yet to upgrade their computers to USB 3.0. When connected to a SuperSpeed USB 3.0 port, consumers can transfer data at speeds up to 5 Gb/s. At that rate, a two-hour HD video will transfer in as little as three minutes. The same two-hour video would take approximately 13 minutes to transfer on a USB 2.0 port.

My Passport Essential, still WD’s smallest portable drive, is available in a 500 GB capacity and comes in five fun colors – Midnight Black, Cool Silver, Real Red, Pacific Blue and Arctic White (Arctic White only available in EMEA and APAC). My Passport Essential SE portable hard drives are available in 750 GB and 1 TB capacities and come in stylish black, silver, metallic blue and metallic red colors. The pocket-sized My Passport portable hard drives are powered directly through the USB cable; no separate power supply is needed.

My Book Essential, the world’s number-one selling hard drive, also impresses with its small footprint, sleek design and high-capacity storage ranging from 1 TB up to a massive 3 TB3. The drive is compatible with both USB 2.0 and USB 3.0 ports, and uses WD SmartWare visual backup software.

“With more and more devices like the iPod touch®, iPhone®4 and other smartphones adding video-capable cameras, digital video is becoming ubiquitous. Most homes already have thousands of photos and music files, increasing the need for storage around the house. Having the extra capacity to store these files and move them around quickly is becoming a big issue for many consumers around the world, WD’s newest line of My Book and My Passport external hard drives features the latest USB 3.0 connection technology, which more than triples the speed to transfer media files, but still works with today’s USB 2.0 ports. In addition, consumers can take advantage of the highest capacity available on external hard drives with the new 3 TB My Book Essential drive.” – said Dale Pistilli, vice president of marketing for WD’s branded products group.

Features:
My Book Essential external hard drives, My Passport Essential and My Passport Essential SE portable hard drives feature:

  • Dual USB 3.0 and USB 2.0 interfaces;
  • Up to 3x faster transfer rates when compared to USB 2.0;

Free Raid Data Recovery Software – ReclaiMe Free RAID Recovery

Free RAID recovery software to recover RAID 0, RAID 5, RAID 0+1, and RAID 1+0. Recovers array parameters such as disk order and parity location.

ReclaiMe Free RAID RecoveryFile Name: ReclaiMe Free RAID Recovery
Publisher: Reclaime.com
Raid Supported: RAID 0, RAID 5, RAID 0+1, RAID 1+0
Price: Free

What can ReclaiMe Free RAID Recovery Do?

1. Recover the following RAID parameters:

  • Start offset and block size;
  • Number of member disks;
  • Member disks and data order;
  • Parity position and rotation;

2. Once you recovered the parameters, you can

  • Run ReclaiMe data recovery software to recover data from the array;
  • Create the array image file;
  • Write the array to disk;
  • Save layout to the XML file;

How to recover RAID data by using ReclaiMe Free RAID Recovery?

1. Download, install, and launch ReclaiMe Free RAID Recovery software.
2. If it is needed, open or create disk image files of the member disks using the Disks button.
3. Decide on the type of your array

  • For RAID 0 select a minimum of two devices from the list and click Start RAID 0
  • For RAID 0+1 and 1+0, select all the available member disks and click Start RAID 0. It is required to select a minimum of two disks.
  • For RAID 5, select all the available member disks and click Start RAID 5. Minimum of two disks is required. ReclaiMe Free RAID Recovery software can recover RAID 5 with one disk missing.

4. Wait until the program completes detecting the parameters. It can take from a couple of minutes to several hours. The process completes when either Scan progress or Confidence is completely filled. Note that Scan progress always grows while Confidence may decrease.
5. At the step all the parameters have been already restored. Then you can select:

  • Run ReclaiMe to recover data. If ReclaiMe data recovery software has been already installed on the computer, then it is launched in RAID recovery mode and displays the partitions on the array. If you do not have ReclaiMe, you will be offered to download ReclaiMe data recovery software.
  • Save layout to the XML file. Save the recovered array parameters to the file in XML format. Note that you can open this file in ReclaiMe and start to recover data off the array using ReclaiMe RAID recovery mode.
  • Use with other data recovery software. Provides step-by-step instructions on how to transfer the recovered parameters to certain well-known data recovery tools. Note that the instructions are created for each particular case of RAID and you should follow them exactly. Should the need arise, the instructions can be copied to the clipboard using Copy to the clipboard button.

Before you start your RAID recovery, please consider the following:

  • If one of the member disks of RAID 5 or RAID 0+1 is physically damaged (produces unusual sounds, e.g. clicking or repeated spin-up and spin-down sounds), don’t use this disk for the recovery.
  • If you cannot avoid using a physically damaged disk, say, for RAID 0 recovery, try to create the disk image file – use Create disk image under Disks on the toolbar in ReclaiMe Free RAID Recovery software.
  • If you have a hardware RAID, you should
    1. Clearly label the member disks, the cables, and the controller ports, so that the original setup can be reassembled if need be.
    2. Disconnect the array member disks from the RAID controller and then attach them as a separate/standalone disks to a non-RAID controller. ReclaiMe Free RAID Recovey needs to access the disks separately to be able to reconstruct RAID parameters.
  • If you plan to recover data once the RAID parameters are restored, prepare a free disk space equal to the amount of data which you are going to recover.

Seagate Self-Encrypting Laptop Hard Drive First To Win Key U.S. Government Certification

Seagate Self-Encrypting Laptop Hard Drive Seagate’s Momentus Laptop Hard Drive Earns FIPS 140-2 Certification, Clearing Way for Deployment of Drives by All U.S. Government Agencies and Regulated Industries such as Healthcare, Defense and Finance.

September 14, 2010, seagate announced that its groundbreaking Momentus ® Self-Encrypting Drive, the world’s first laptop hard drive with built-in encryption to protect against unauthorized access to information on lost or stolen mobile computers, has secured FIPS 140-2 certification from the U.S. National Institute of Standards and Technology (NIST).

The key government certification clears the way for deployments of Momentus Self-Encrypting Drives (SEDs) by all U.S. and Canadian federal agencies, many state and local governments, and regulated industries such as healthcare, finance and defense required to use FIPS-certified gear to help protect sensitive data on PCs and computer networks. Many utility, education and transportation entities also have adopted the FIPS (Federal Information Processing Standard) 140-2 standard to lock down confidential information. Foreign governments in addition to Canada also recognize FIPS-validated products. The Momentus SED is the first hard drive with native encryption to earn the FIPS certification.

“The FIPS 140-2 certification exemplifies Seagate’s commitment to security standards that enable the widespread adoption of encrypting hard drives for laptops and other computers as the explosive growth of laptop PCs puts more sensitive personal and business information at risk, today’s NIST approval gives our system builder and end-user customers the peace of mind that Momentus ® Self-Encrypting Drives deliver the full power of government-grade security.” – said Dave Mosley, executive vice president of Sales, Marketing and Product Line Management at Seagate.

The FIPS 140-2 seal of approval comes three years after NIST, the federal agency focused on promoting product innovation by establishing technical standards for government and business, certified the Advanced Encryption Standard (AES) chip built into the Momentus drive. Seagate has shipped more than a million of its self-encrypting laptop drives since their introduction in 2006.

See Seagate’s FIPS 140-2 certificate here: http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/140crt/140crt1388.pdf .

More information on NIST and FIPS 140-2 is available on the NIST website:
http://csrc.nist.gov/groups/STM/cmvp/index.html

Seagate® Momentus® hard drives deliver high capacity and performance along with innovative technology, such as self-encryption and free-fall sensors. If you require feature-rich, reliable, robust and secure laptop storage, Momentus drives are for you.
