How Much is Enough
The 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 »
Hard Drive – Size does matter
Hard drives come in many forms and shapes, the most common are the 5 1/4″ and the 2 1/2″ the first appearing on desktops and the later on laptops. As of this year, the highest capacity hard drive has topped the 2TB capacity and is set to improve further as data storage technologies improve. The smallest hard drive ever made was a 0.85″ hard drive developed by Toshiba for use as if it were an SD/MMC card for data storage on a computer or mobile devices. The two forms of hard drives have stood the test of time due to the fact that flash memory has experienced such a boom prices have fallen making them a more viable storage solution for smaller needs. The speed at which these drives spin can range from 5,400 to 7,200 rpm the later of which was the long standing standard for server-type SCSI hard drives that were very expensive. Most mobile computers (laptops) come with a 5,400 rpm drive due to the sound considerations when using the device, the faster the device the louder the sound (the spinning sound or hum you hear). You can in theory use faster hard drives on mobile computers but they would reduce battery life and make it noisier defeating the overall design of the laptop. Continue reading »
S.M.A.R.T. – Saving your data before you know it!
SMART is a monitoring technology build into the electronics of hard drives as a way of the computer monitoring it’s performance and may give warning of pending failure. Though the system is generally one that works without a hitch, it cannot protect you from sudden hardware failure which leaves the drive non-operational. Sudden hardware failure is estimated to account for 60% of all drive failures, and is attributed to rough handling or drops and knocks say a laptop falling onto the floor from your desk. They are designed to withstand specific amount of impact force (measured in G’s) that means a hard drive may survive a fall from a 3-foot desk. Continue reading »
Two essential tips
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.
MTBF – Meaure of Reliability
Mean-Time-Between-Failure or MTBF is a term used to describe the reliability of the parts of a computer system from a technical standpoint describing reliability and is measured in hours. The higher this number the more reliable a computer part is. with respect to hard disk drives, particularly IDE drives this denotes the number of hours before it fails or parts of the electronics, motors and bearings can last without any failure. This is an older measure used by the computing industry when hard drives were still quite steeply priced with the best ones reserved fro use on servers and other high demand uses. Ide has long been replaced by the SATA standard which eliminates the thick IDE cable that blocks airflow within a computer’s casing preventing proper cooling.

ソリッドステートハードディスクが現在の回転ドライブと過去10年間ハードディスク市場を構成した部品を取り替えます。 ハードディスク製造の最新技術は現在、多くの産業と防衛製品に適用されています。 ソリッドステートは最高度の性能と信頼性を提供します。 通常のIDEハードディスクの動く部品は負担や摩擦過多のため、メデイア全体で一番の弱点でした。 ソリッドステートのハードディスクは基本的に軽量で、2.5インチと3.5インチのハードドライブを作動するほどのパワーを必要としません。また音響学的特性がありません。 この最新の技術は市場から力強い支持を得ていますが、弱点もあります。 日々のコンピューター使用によるソリッドステートハードディスクの唯一の問題は耐久性です。 そのため、アドトロンハードディスクは対策を最新のリリースに組み込みました。 これはハードディスクにおける最新技術です。 負担や圧力にも耐えることができます。 I/Oアプリケーションにおいて優れた書込み耐久性を持ち、ホストやメディアへのバッファとしてのメモリーキャッシュも必要せず、最高の読込み、書込み率を維持できます。
Hard Disk Error – Hard Disk Not Found
This is an error message we all hate we’d never see but these small yet terrible precision storage devices are electro-mechanical and they will eventually wear out. Before you consider burying the darned thing, try getting hold of a new IDE cable and replacing that. The cable is made up of several dozen wires that tends to cook up in the PC’s case especially if you don’t have ample cooling and you love to over-clock the system that makes it hot enough to cook and egg on.
Another thing you might want to try is to unplug the IDE cable at both ends and try re-seating them. The heat within your PC causes thermal expansion which can loosen cables(though very rare), but they can happen. check the power connector and switch with another one or a free one you may have. Of course you’re doing this all after you’ve shut it down and pulled out the plug from the wall socket, waiting a few minutes for the residual charge in the power supply to dissipate. you should also touch the power supply to get rid of the very nasty static charge you maight have picked up walking on your carpeted floors.
ハードディスクはどうやって動いているのか

ハードディスクには磁気を帯びた数枚のプロッターがあります。 プロッターがついている軸がこれらを高速に回転させ、リード/ライトヘッドが読み/書きする情報をプロッター上で探します。 ハードドライブの有効性はどれ程の量が未使用であるか、フラグメントの割合やデータ転送率により、それはコネクションの種類とドライブの回転数によって変わってきます。ハードドライブを購入する際に、二つの製品、例えば一つの160GBドライブと 二つの80GBドライブの値段を比べるとします。二つのハードドライブがあれば、一つが悪くなっても全てが無くなる訳ではありません。しかし今日のハードドライブは、乱用しなければ、長持ちするハードウェアで、 面倒な事の無い長期に渡るデータ保管を約束します。
Hard Disk Failure

Hard Disk failure is one big factor in loss of important data stored inside your computer. We lose at an average, 44 percent, of our data stored due to our hard disk’s malfunction. It is important to know that hard drives are mechanical equipments or hardwares. It is prone to wear and tear. It has a specified life cycle. If you use them correctly and with its normal operating conditions, you can fully utilize it. But if you abuse its use, usage can further be shortened. Here are some reasons why hard disk failure occurs;
Head Crash accounts for the majority of the percentage if hard disk failure.
Sudden Temperature can influence directly the occurrence of data loss
Electro Static Discharge during installation can lead to electrical failure

Solid state hard disks can now replace the rotating drives and parts that have comprised the hard disk market for the last decade. The latest technology in hard disk production is currently being used in a number of industrial and defense applications. Solid state provides the highest possible degree of performance and reliability. The moving parts of the ordinary IDE hard disks are virtually the weakest link of the entire medium because it is prone to tremendous strain and friction. The solid state hard disk is basically lightweight, it needs less power to run than the common 2.5″ and 3.5″ hard drives, and it has no acoustic signature. While the latest technology is enjoying great support from the market, it is not without its weak points too. The only major flaw that needs to be taken care of a solid state hard disk when used into the everyday stresses of computing, is its durability. Thats why, Adtron Hard Disks came up with their latest product release. The latest in solid state hard disk technology. It is capable of withstanding the strain of pressure. It offers exceptional write durability in I/O applications, it can sustain the best read and write rates without using up precious cache memory as a buffer of the host and media.
