Hard drives can get quite cluttered and can easily get crammed with unwanted files and others and as any techie knows, a deleted file here rarely gets deleted in the real sense. A deleted file normally has the header information deleted with the space it occupies made available for storage. The file fragments are still on the hard drive till they are over-written by new data that is stored over it. Time will come when a computer system may become sluggish and the only way to return it to it’s full glory would be to do a full format and re-install of all the necessary drivers and software.

HD technology has revolutionized the way we use, save and share media in it’s many forms and shapes. Hard drives that used to live within the hot CPU’s of our desktops can now be directly connected to smart-technology TV’s and other devices allowing information such as online purchased movies to be played directly on-screen without a need for a PC. The realm of the external SATA-hard drive and the advent of the mobile mini-laptops changed the way we browse the net. Read more…
Any techie would know the term, and it’s not a game or video card, it’s the ability of a hard drive to survive drops or fall shock which is the main cause of drive failure of hard drives the world over. Accounting for more than 60% of all reasons of hard drive failure, the other 40% divided between hardware/manufacturing defects and others it is one problem that is so hard to address due to the very nature of the people who uses these ultra-high precision pieces of machines that allows us to use computers day after day after day. Some would swear by brand loyalty and some swear with the latest technological innovations like the release of the first terabyte drives and more. Read more…
While it’s a fact that running your disk defragmenter is a bit of a hefty job, it still is nonetheless important in maintaining your hard disks’ smooth operation. Disk defragmentter rearranges the files in a your hard disk, ensuring for more efficient use of hard drive space. Running disk defragmenter not only improves your hard disks’ health but it also boosts startup / booting times of your PC or laptop.
Running disk defragmenter is easy – just go to the Start Menu, look for System tools under Accessories, and then run Disk defragmenter. Now, to make the waiting easier – the bigger the hard disk, the longer HOURS it will take – simply run the program when you don’t plan to use the computer, like when you go to bed or when you’re planning a movie / TV series marathon.
First, the SATA standard has reduced the wires needed for connection from the IDE’s thick cables down to an 8-pin connector. This eliminates the need for the bulky cable and also improves overall PC cooling efficiency allowing better air circulation inside the casing. The other and most enticing difference is the ability to hot-swap meaning hard drives can be replaced without having to turn off the power of the computer system as long as there is no read/write operation in progress.

Fujitsu Asia introduced the MHW2BK series of Serial Advanced Technology Attachment (SATA) hard disk drives (HDDs).
Made mainly for blade server, industrial, robotic, surveillance and telecommunications operations, the MHW2BK series of HDDs has been considered with a spindle speed of 7,200 revolutions per minute (rpm) and a maximum data rate of 3 gigabits per second (Gb/s).
The product line also incorporates features to decrease the adverse effects of rotational vibration (such as read or write failures) which may arise when multiple drives are mounted on a single chassis and rotated at high speeds, for increased operational stability.

CPRM or Content Protection for Recordable Media is a mechanism for controlling the copying, moving and deletion of digital media on a host device, such as a personal computer, or other digital player. It’s already used in specific removable media, and is now being proposed for inclusion in the ATA specification, for hard drives.
