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.

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.

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

Adtron Hard Disks

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.

How Hard Disk Works

Your hard drive has a number of magnetized platters. The spindle spins the platters at a very fast speed while a read/write head scans over them both looking for reading and writing information. The effectiveness of your hard drive depends on how much of its capacity remains unused, fragmentation and its data transfer rate, which in turn is dependent on its connection type and the drive’s spin rate. In buying a hard drive, you may want to compare the prices of say a 160GB drive against two 80 GB drives. The thing with 2 hard drives is that, If one drive fails all is not lost. Although today’s hard disks are durable pieces of hardware, so long as you do not abuse them, it can provide you a long time of hassle free data storage.

The IDE Hardisk

Integrated Drive Electronics (IDE) hard disks have been around for quite a few years.  Prior to these drives, hard disks were interfaced to a PC motherboard via an extension board known as a hard disk controller.  The drive did most of the mechanical stuff and performed essential electronic/servo functions; the controller told it in detail what to do.  The development of the IDE hard moved most of the electronics and firmware (low-level software on a chip) from the controller to a printed circuit board on the drive itself.  In the process, a buffer/cache’ memory was added to the electronics to speed-up the process of reading and writing hard disk drive data.  The drive got “smarter.”  Overall costs went down and performance went up.
A much simpler board, usually identified as an IDE Controller, interfaced the IDE hard disk to the motherboard bus.  The term IDE Controller is a misnomer.  It is really nothing more than a bus interface and an interface and connector for the IDE cable going to the drive.  The actual controller is on the drive.
