IDEハードディスク: なぜこのような名前で呼ばれるのでしょう?

January 22nd, 2015

どのハードディスクもディスク制御装置を介してマザーボードに接続されています。ディスク制御装置はハードディスクとOSの間でブリッジの役割を果たすものです。ユーザがハードディスクのデータにアクセスできるようにハードディスクとマザーボードはデータバス(回路間のデータ通信経路)で接続されています。データバスとは電子データを伝達するパイプのようなものです。

データバスには、シリアルATA(SATAハードディスクに使用される)とパラレルATA(IDEハードディスクに使用される)の2種類があります。IDEとは「インテグレーテッド・デバイス・エレクトロニクス:Integrated Device Electronics」の略です。パラレルATAは以前IDEと呼ばれていました。そのためパラレルATAを使用するハードディスクはIDEハードディスクと呼ばれるのです。

Two essential tips

January 15th, 2015

1. Run Disk Degragmenter.

You can find it in Start > Program Files > Accessories > System Tools. Disk Defragmenter effectively sifts through your files and organizes them, thereby saving you hard disk space as well as speeding your system up. Since it takes a long time to get done, it is recommended that you run Disk Defragmenter just before you have a task or errand to do so you don’t have to endure the long wait.

2. Use a hard disk fan.
Electronic processes generate a lot of heat for the hardware, which is ironic, since heat is the major factor in the degradation of computer equipment over time. Especially for bigger and faster hard disks that spin at faster rates, you need a fan to help dissipate the heat and make your HD last longer.

Upgrading? Better destroy all data on your Drive

January 8th, 2015

Many companies observe strict policies regarding computer hardware and the data they contain. But many of us common folk fail to observe the same and sometimes end up in trouble for such irresponsible acts. May they be old digital photos or lewd email backed up on your hard drive, all of these can be used for wrongdoing and should be dealt with in the proper manner.
The simplest way to destroy data is to do a software hard format using the Operating system’s long format option. Going a step further, you could get your drill and drill a few holes through the whole thing just to be safe and then toss it into the recycling bin to be made into new drives. But be safe and do wear proper safety gear and clamp down the drive in a vise to prevent injury.
Keeping information out of the wrong hands is the responsibility of everybody and it does not hurt to be extra careful.

Know the Measurement Jargon

January 1st, 2015

IDE hard disk Post 1Somebody once told me that a mans thing is proportional to the size of his hard disk. Thats totally untrue but it is definitely true that size does matter. Sometimes, during some intellectual boastful conversation, one may actually say a quarter of terabyte instead of 250 gigabytes to make it sound more size-monster.

The capacity of early hard disks is quoted as megabytes. A megabyte can store up to 1,048,576 or 220 bytes. Today, hard disks are commonly in gigabytes. Gigabytes is equal to 1,073,741,824 or 230 bytes of computer storage. Byte, on the other hand is equal to eight bits. A bit is a binary digit, taking up the values of either 1 or 0.

コンピュータ・システムにおけるハードディスクの役割

December 25th, 2014

ハードディスクはコンピュータ・システムの動作において、以下のような様々な側面で主要な役割を担っています。

・パフォーマンス:ハードディスクはコンピュータ・システム全体のパフォーマンスを左右する重要なハードウェアです。システム起動やアプリケーション呼び出しの速度に、ハードディスクの速度が直接影響するからです。同様にマルチ・タスク動作や大量のデータ処理においても重要となります。

・記憶容量:主要記憶デバイスであるハードディスクの容量が大きいほどより多くのデータやプログラムを格納できるのは当然です。

・ソフトウェア・サポート:膨大なOSファイルやアプリケーションを安定して動作させるためにハードディスクが重要なサポートを提供します。

・信頼性:高品質なメンテナンスとバック・アップ機能の組み合わせによりユーザのデータ保護を手助けします。

New Hard Disk Drives

December 18th, 2014

 

I’m no longer surprised whenever something so advanced and high tech comes up. I’m always impressed but no longer surprised. Just this month in Singapore, researchers have developed one of the world’s thinnest hybrid hard disk drives with storage capacity of over 1 terabyte. Woah, right? A typical hard drive is 7mm thick but this one is only 5mm thick. It has bigger capacity too since the typical ones can only store 500 gigabytes. Its perfect for tablets and ultrabooks.

It is called “A-Drive” is a hybrid hard disk drive. It costs less and provides more storage space. How much more? Well it can easily store 250,000 songs!  It is expected to cost around $60 when it comes out soon. There are no exact dates when this product will be available in the market.been developed by a team of researchers from the Data Storage Institute (DSI) of the Agency for Science, Technology and Research.

JTS Corporation

December 11th, 2014

JTS corporation, which is base on San Jose, California, was a producer of IDE hard drive for personal computers. In 1994 Jugi Tandon founded JTS Corporation. The company originally concentrated in making on a new 3″ form-factor drive for laptops. The three inches feature accepted a larger drive storage capacity for laptops with their technology.

Compaq Computers was qualified JTS’s drives and incorporate it with their laptops. They became the supplier of bargain basement priced with good-performance hard drives with 5400 RPM. They produced their product in the southern part suburb of Madras City. In this case reputations on products were noticeable. Upon merging with Atari on February 1996, and getting cash from it, JTS filed for Bankruptcy by December 1998.

Conner Peripherals

December 4th, 2014

Conner Peripherals was known in developing hard drives for personal computers. It was founded in 1986. Finis Conner, John Squires, and Terry Johnson founded the company.

Their first milestone was in 1990 where they set a record of almost 1.337 billion in sales spanning in four years. They were recognized as the fastest growing manufacturing in the United States. Also, they were first of many companies to produce IDE specified hard drives. In 1990 Seagate buy them out. Conner peripherals also started to make tape drives during 1993. In 1998, the company shut down the operation when they can not meet the low-cost demand from the suppliers.

A hard drive and media player in one?

Have you ever thought of bringing a portable video player on the road? Of course, you may think I might be talking about portable DVDs, but no. If you have a wide collection of movies at home, will you bring your CDs with you to your destination? Of course not! That would be too much of a hassle.

To the movie buffs, here’s a treat for you. Chinavasion is again trying to catch up with the big names in the hard drive industry as they have come up with a portable external hard drive that can be used a media player. The player has a 120GB capacity and a 2.5 inches wide screen for viewing. It also has an earphone jack, so you can basically bring it everywhere you go—even in places that value silence.

Deframenting Hard Drive Myths part 1

November 20th, 2014

Stressing the needle because of defragmenting has some truth in it, though gone astray. Defragmenting the hard disk might require a lot of searching and looking as the hard drive reorganizes its data in a contiguous style. Defragmenting lets the read-and-write heads to scan huge amounts of data without searching over the platters.

On the other hand, right after defragmentation, the hard disk is no longer required to search for all the platters for your data. In this way it lowers the amount of head actuator actions as well as intensely increases the performance of the hard drive. For that reason and technically, defragmenting the hard drive will reduce the workload of the head actuator.
