To Slave or Not to Slave

July 3rd, 2015

This is a manually set designation done on an IDe hard drive that tells the computer system whether the drive is the boot drive or primary or secondary. This is vital for it tells your CPU where the boot drive is that contains the Operating system(usually windows). This can be determined with a quick check on the label of the drive where the pin designations are shown.

Setting this, you take a look at the IDE hard drive(preferably when it is still not installed on the computer system) in between the IDE cable and the power supply. There are normally three pairs of pins, one for master another for secondary or slave and the last one is for auto-detect with the computer system determining on it’s own which is which.

ハードディスク容量のアップグレード Part 1

June 26th, 2015

誰もがより大きなハードディスク容量を求めています。予算に余裕があるのならぜひ実現してみてください。ほんの少しのアップグレードで快適になりますよ。IDEハードディスクをアップグレードするには、古いディスクをはずして容量を増やすための新しいディスクを取り付けるだけ。どちらの作業もちっとも難しくありません。

どのIDEハードディスクにも標準タイプのピンとソケットが採用されています。ハードディスクを取り換えるだけなら、手順はごく簡単です。ディスクからIDEプラグと電源プラグを引き抜いて、ハードディスクドライブを筐体に固定しているネジをはずして新しいハードディスクを差し込むだけです。

Hard Drive Myths part 3

June 19th, 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.

Formatting Hard Drive Myths part 5

June 12th, 2015

It is true that formatting will eliminate the bad sectors and will be replace with good sector on the spare section that part of every hard disk. But the performance will suffer because the heads will seek on the spare section in replacements of bad sectors. Bad sectors are signs of bad hard disk. Basically, it means that there something wrong with the hard disk. Bad sectors create debris on the platter and can cause to damage the hard drive.

Additionally, spare sectors are limited on any hard drive. Then once the hard disk runs out of spare sectors, formatting can not replace those bad sectors.

How Much is Enough

June 5th, 2015

harddrivesThe ability to connect a specific hard drive is generally limited but he architecture of the motherboard and bios as a matter of fact with most today limited to 500GB in capacity. Attach a larger drive and you may not be able to utilize the full capacity of the drive which you may find out in the detected drive displayed within the BIOS setup screen. Though most motherboards now use auto detect, detecting and getting the information about the hard drive from the internal electronics, there was actually a time when you had to know the parameters of the drive for one to mount it and use it properly. IDE today has become an older standard, replaced by SATA which has faster transfer rates and other speedy attributes. They also have a slimmer connector that lessens the restrictive effect the former 80-wire flat cable had on the overall computer system. Continue reading »

Upgrading? Better destroy all data on your Drive

May 29th, 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.

Formatting Hard Drive Myths part 4

May 22nd, 2015

There is a myth that bad sectors can be repaired once it was reformatted. A bad sector is an area where the hard disk cannot be written nor read properly. It may due to program-related problems that result in a logical bad sector. Bad sectors that are software related can be restores by formatting using any logical repair utility.

But in case the problem is due to eroded media or the hardware is directly damaged. Such physical bad sectors can no longer be repaired using any logical repair utility and formatting it will not restore them. Formatting them, however, can replace those bad sectors with spare sectors.

テープドライブに対するハードドライブ

May 15th, 2015

ハード・ディスク・ドライブの登場以前には、主にメインフレーム・コンピュータ用の主要記憶メディアとして「テープ・ドライブ」が使用されていました。2つの記憶メディアには以下のような特筆すべき違いがあります。

・テープ・ドライブでは、薄いプラティック製テープの表面に磁気記録材料がコーティングされているが、ハード・ディスク・ドライブでは層状に重ねられた高精度ステンレスや高精度ガラスを利用している。

・ハード・ディスク・ドライブ上では、テープドライブと比較して、より高速でのシーク動作が可能となった。

・テープ・ドライブのヘッドはメディアに物理的に接触するが、ハード・ディスク・ドライブでは物理的な接触はせずにファイルを読み取る。

・ハード・ディスク・ドライブではテープドライブよりも比較的小さいスペースに膨大なデータを格納できます。

4TB Hard Disk Drive

May 8th, 2015

This year has been the unveiling of 4TB hard disk drives. Companies have been pushing for better and bigger storage and better performance. Both Toshiba and Western Digital has released their new products towards the end of the year.

Toshiba said “The range has been developed with the storage challenges presented by big data and cloud services in mind,” It is 50% increase in storage capacity than the last ones they have produced and 18% faster too!  The sample shipments will be available beginning this month and a bulk produce by the New Year.

Western Digital 4TB WD Black drives have maximum capacity, says Matt Rutledge, VP of Western Digital’s client storage group. He continued on “Maximizing the features and functionality of power computing applications such as gaming, multimedia and video editing, the new WD Black 4 TB hard drives offer capacity and performance – without compromise.”

Both of these products are expected to drive sales by next year, making the future of hard drives more impressive.

データ転送速度

May 1st, 2015

ハードディスクドライブに書き込まれたデータは、人間が読める言語ではなく、2進数を表す「1」と「0」の連続による数列です。これはコンピュータの理解できる唯一の言語であるため一般的にはマシン語と呼ばれます。ファイルには xx KB(キロバイト)xx バイトというようにそれぞれサイズがあります。1バイトは8ビットで構成されており、1つの文字を表現できます。データ転送速度とはあるデバイスから別のデバイスへとデータが転送される速度です。

IDEハードディスクの仕様書では「転送速度は xx ms(マイクロセカンド)」というような記述を目にすると思います。重要なのはデータ転送速度の値が小さいほど、ユーザやアプリケーションが要求したデータを、ハードディスクがより速く読み、メディアへ書き込んで読み出せることです。データ転送速度により、コンピュータ・システムのユーザはより速くタスクを実行できます。
