Full-disk encryption for all computer drives

Wednesday, February 18th, 2009

The six biggest computer drive manufacturers of the world have published this week the final specifications for single and full disk encryption standards which capable to be used in all hard disk drivers, encryption key management applications and solid state drivers. After it is enabled any disk which uses these specifications would be locked without a password and this password would be required even before booting the computer. The three specifications of The Trusted Computing Group can cover storage devices in desktop computers and consumer laptops and also as enterprise class drivers when used in disk storage arrays and servers.

Robert Thibadeau the TCG chairman and chief technologist in Seagate Technology said that this entirely represents capable commitments from all disk driver makers in this world. He further said that they are protecting the data when at rest. When the laptop is powered down or when a USB drive is unplugged or if administrator has pulled down a drive from the server it can actually be brought up and used without feeding in a cryptographically powerful password. However if you don’t have it then you probably won’t be able to sell it even on eBay.

When you are using a single and full disk encryption specification all the drive manufacturers can break your security to firmware of their products while even lower the cost of production and increase the efficiency of security technologies. When an application or an operating system writes data to its self encrypting drive a bottleneck is not created by any software which might have to interrupt the I/O stream and convert your data so that the user can see the encrypted data at I/O speed without any slowdown. Robert Thibadeau further said that the encryption machinery also does not use any power. When the machinery reads the data from a drive it also displays it to your clearly as it is completely transparent and clearly readable.

The Trusted Computer Group (TCG) includes companies like LSI Logic, Wave Systems, Western Digital, UNLINK Technology, Toshiba, IBM, Samsung, Seagate Technology and Hitachi GST. Jon Oltisk the analyst in Enterprise Strategy Group said that in five years time you would see your drive coming off the production line and it would be encrypted with virtually zero cost for it.

Included in the three specifications is the Opal Specification that describes minimum requirements for all the storage devices in laptops and computers. The other is Enterprise Security Subsystem Class specification and this is aimed at drives in high volume applications and data centers where generally there is less security configuration during installation. The third specification includes the Storage Interface Interactions specifications. This specification describes how the previous Storage Core specifications of TCG and other specifications interact with other standards regarding connections and storage interface. For instance this specification supports a huge number of transports that include ATA serial and parallel, ATAPI, Fibre Channel and SCSI SAS. Most of the drive manufacturers including Hitachi, Fujitsu and Seagate have already supported this specification for the same drives.

Toshiba Satellite M305-S4835

Tuesday, December 16th, 2008

Finding the perfect laptop that is adaptable enough to fulfill all your portable needs and your home computing needs can be a bit tough. However the Toshiba Satellite M305-S4835 has perfectly managed to strike both ends of computing needs. The laptop combines a frame which is light enough to carry along while providing decent screen which is full of features that are commanding enough to handle most multimedia tasks and well-organized enough to keep powering rather running out of juices. Overall, the new Toshiba Satellite M305-S4835 includes almost all the requirements for a perfect portable and compact home laptop needs which a reasonable starting price to make it an excellent package.

This compact M 3.5 which is nearly about 6.9 x 13.2 inches perfectly fits a travel bag but regarding its thickness, Toshiba might have gained the idea from Apple’s 0.7 inch MacBook. However you should know that the in built optical driver is actually the big and essential part that makes the system thick. The weight of the notebook is not more than 5.5 pounds including its super battery.

If you need an easily portable laptop then a 14″ screen will generally be the maximum size to be considered which makes the 14.1″ screen of this laptop a perfect option. This is because with a 12″ screen laptop you can loose important features while the 15″ can be really big to carry about. The widescreen of Toshiba Satellite M305-S4835 is bright where photos and movies are popped wit the help of glossy layer of the screen. However the 1,280 by 800 resolution is almost the common resolution that is found in most of the laptops which is rather quite good.

Although facing a bit discouragement in its design the Toshiba Satellite M305-S4835 offers you more feature for money equal to purchasing a 13″ MacBook. The M305 features three USB ports which function the same as those of HP dv2800t and Dell 1310. However these three USB ports offer sleep and charge feature of Toshiba meaning they can easily power an iPod, a GPS device, a cell phone or any other external USB peripheral. The laptop also features a dual layer DVD burner including an eSATA port and a FireWire port. Apart from this the Toshiba Satellite M305-S4835 also comes packed with Centrino 2 Wi-Fi, however sprint WiMAX and Internet WWAN are currently not supported.

The performance is very satisfying for a laptop in this particular size and price range. The Toshiba Satellite M305-S4835 includes the 2.0-GHz Intel Core 2 Duo P7350 which is located at the lower end of the processor line and is very powerful or the same as that of P8400 of Dell 1310 and P8600 of MacBook. This is made up by the laptop through its impressive 4GB memory. Additionally the laptop comes with Windows Vista 64-bit operating system and so it can technically use all the memory that is installed according to the task. Although the Intel integrated graphics of this laptop are perfectly fine for any laptop user the MacBook 13 inch and Dell 1320 manage to make us more powerful, but is makes a perfect power laptop package with reasonable price range.
