Formatting Hard Drive Myths part 3

February 26th, 2015

Anytime bad sectors of the hard drive will suddenly appear whether you just plain using the hard drive or formatting it. The number of bad sectors is definitely will increase as the time goes by.

This myth has some truth in it though. After formatting bad sectors are probably noticeable. This happen because in formatting in formatting the hard drive utility looks for the “new”You will probably notice more bad sectors after formatting. Consequently bad sectors are already there and what happen was revealing them.

So, in a failing hard disk the number of the bad sectors will not increase when you format it. Bad sectors are being revealed in doing so.

Hard drive dock and more.

Look at your workplace. Have you ever wondered how you can get rid of all those wires hanging around? No, I am not saying that you must go wireless with all your things as you might spend a lot of money on buying new gadgets when in fact the old ones are still working. You just have to be a little organized about your home wiring system as this may cause a lot of accidents. But believe me, even if you decided not to go wireless, your workplace can still be as organized as you can imagine.

How about getting some of those docks made by Unitek? They are currently selling in the market a dock wherein a lot of computer gadgets can be connected. Aside from the 4 card reader slots and the 2 USB ports available, you can even insert an external hard drive in it.

Secure Erase

February 12th, 2015

Identity theft and data loss may leave the company at stake being liable under federal law. HIPPA, Sarbanes-Oxley, Graham-Leach-Bliley and other state laws are example of the federal laws. Penalties include fines and imprison of 20 years plus results of civil suits if any.

Secure Erase makes it safe to avoid the crimes. It is a set of command mostly incorporated in ATA drives. This technology is available since 2001. But it was disabled by most of motherboard BIOS. That’s why many of users don’t know it besides Murphy’s Law was still enforced. Secure Erase is a gun aimed right to all of the data in the PC.

IDE Drive cables

February 5th, 2015

There are basically two cables that come with hard drives may they be SATA or IDE, the power and bus cable. The ribbon cable as it is known due it’s resemblance to one in an IDE drive is usually colored grey but it can come in many colors depending on the motherboard manufacturer. Should you ask if they do fail, yes they do and it may bring about a myriad of mysterious events such as disappearing drives or intermittent connection to one. Simply replace the flat cable and re-seat the power supply chord to diagnose it properly and check for the usual humming(no clicking) of the drive as it spins up to proper operating speed and you’re good to go…

Hard Drive Myths part 3

January 29th, 2015

The truth is current design of hard disk’s head actuators are not power-driven by any motor. Previous design of the head actuators are actually powered by a stepper motor. But currently head actuators use the voice coil instrument that uses electromagnetic power to stir the heads. In short, head actuators don’t have a motor to fail and not powered by any mechanical motor.

In addition, take note that head actuators’ automatically when there are power cuts meaning it is not an active process. Head actuator uses spring to park itself. The spring retracts the actuators when the power is cut while it moved against the spring tension when active.

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。
