4. release the hard drive from its slot (kind of like a hard drive laptop hard drive with IDE interface), replace with a capacity that you want. I switched to Samsung 160GB IDE (Creative FUJITSU 60gb IDE).

5. Reinstall all of the sequence 3, 2, 1. slowly in the installation again, not too forced. because everything is in conformity with the body of the protagonist.

6. after everything is installed, we flash FIRMWARE make the new occupants, 160GB. a few items needed to make the flash of the protagonist:
a. creative nomad zen extra 160GB + usb + charged.
b. windows XP sp2 + windows media player 10
c. the latest firmware from creative.com for these nomads.

AMD Phenom II X6 versus new intel Quad Core

For version X6, AMD Phenom II X6 prepare 1100T to replace Black Edition Phenom Black Edition II X6 1090T is a flagship AMD previously, the new version of the X6 has a clock of 3.3 GHz, 100MHz faster than the 1090T, and has a Turbo Core Frequency to 3, 7GHz with a TDP of 125W and is still based on 45nm thuban Die with 6 Core which contains 128kB L1 cache and 512KB L2 cache per core and 6MB of shared L3 cache, IMC that supports DDR2 1066MHz and DDR3 1333MHz which means it can be used both on the socket AM2 + and AM3 .

Besides releasing a new flagship for Six Corenya, AMD is also preparing a more affordable version of the X6 with Phenom II X6 1065T (2.90 GHz, non-BE, 3:40 GHz Turbo), Phenom II X6 1045T (2:50 GHz, non-BE, 3:20 GHz Turbo) . As for the version of the Quad-Core, AMD is also preparing a version higher than the Phenom X4 II 970 BE newly launched, the Phenom X4 II BE 975 with a clock of 3.6 GHz and the unlocked multiplier like other BE family, and still use the core Deneb.

but I think 6 MB L3 cache is still losing the same intel I5 who already have a cache of 8 MB, but it seems AMD does not provide features such as Hyper Thread intel i series. For Price and Performance AMD wins, but the affairs of Performance and electricity AMD still less than the intel. If want to beat intel i-series AMD should be able to lower the watt TDP of the processor that is still less than the intel.
Utilization and efficiency of this power should be taken into consideration the AMD, especially now that it was the PSU manufacturers are aggressively target pairs of 80 + efficiency in its product.

Turbo features offered by AMD seems to be the nail on the step. It should have a modern processor is designed to run faster when it is needed eg when running heavy applications or when playing games. Instead the processor should be designed as smart as possible to reduce its performance when it is not too needed to work hard in order to further save energy consumption.

How to buy LCD for gaming

Monitors with LED backlight, often referred to as LED monitors (which is not quite correct because true LED monitors are those huge ad billboards in which the image is indeed formed by LEDs), have been quickly gaining popularity. They were expensive, premium-class products at first, but now, for example, BenQ offers a 19-incher with LED backlight for less than $200.

LED LCD and LCD the difference is in the backlight, resulting in a distinguished CONTRAST RATIO much different, this contrast ratio is the distance the color Black to White. the farther the real picture.

Plasma TVs have the Black Level Color distinguished better than LCD, but have a need for a high power, LED technology has a Plasma Black Level equivalent, but the electricity more saving for LCD. 2 ms response time and full HD resolution, it is a necessary condition for gaming

But if we are going to talk about the real, not marketing, advantages, we want to know what type of LED backlight we mean. There are three of them available today:

  • A LED backlight based on RGB triads, each triad including one red, one green and one blue LED. This type of backlight ensures an excellent color gamut and very pure colors but is only used in professional monitors (NEC’s SpectraView Reference 21, Samsung’s XL20, XL24, and XL30) because it is expensive and not economical. The only attempt to develop a rather inexpensive monitor with RGB triads that I know of is ViewSonic’s VLED221wm. And it is a downright failure because the manufacturer had to save on everything else, and particularly had to install a matrix with poor viewing angles.
  • A flat backlight based on white LEDs. As there is only one third of the total amount of LEDs here, this backlight is much cheaper than the triad-based backlight, but it cannot deliver an extended color gamut. In the backlight of this type LEDs are uniformly distributed in the plane parallel to the matrix, which allows setting the backlight intensity differently in different parts of the screen when necessary. This is the further development of the dynamic contrast technology. It is currently employed in LCD TV-sets only.
  • An edge backlight with white LEDs. The LEDs are placed in a line along the edge of the matrix, and the uniform brightness of the screen is ensured by a special design of the diffuser. This backlight does not offer the option of zonal control over brightness. It does not ensure an extended color gamut, either. Instead, it is economical and compact, which makes it popular among notebook makers. It is also often installed in monitors. By the way, as opposed to cold-cathode lamps, light-emitting diodes do not contain mercury and thus can be recycled easier.

So, ordinary home monitors usually come with an edge backlight based on white LEDs. Other types of LED-based backlights may become popular in the future, but that’s what we have now.

The manufacturers often promise that a LED backlight affects nearly all of a monitor’s characteristics including contrast ratio, color accuracy, brightness uniformity. Is it really so?

Contrast ratio is only determined by the characteristics of the LCD matrix, namely by the ratio of the transparency levels of open and closed pixels. It depends neither on the backlight nor on the type of that backlight.

Dynamic contrast. As opposed to gas-discharge lamps, LEDs can be lit up instantly or turned out completely, which leads to extremely high levels of dynamic contrast (to remind you, it is calculated as the ratio of white on an all-white screen to black on an all-black screen). But in real applications, for example when watching a movie, there are no absolutely black frames even in the credits. Most of the time there is something on the screen besides blackness and a monitor with a huge specified dynamic contrast will never have the chance to deliver it in practice. As a result, there is no practical point in increasing the dynamic contrast higher than 10,000:1 which has already become standard for any monitors, including those with a backlight based on fluorescent lamps.

Uniformity of brightness. As I’ve said above, home monitors utilize an edge backlight, i.e. a line of LEDs along the edge of the matrix. The whole screen is lit by means of a special diffuser. This is the same design as is used in notebook displays and in inexpensive models of monitors with lamp-based backlight: the lamp is also located near the edge of the screen (more expensive models have a few lamps, located behind the matrix). The uniformity of brightness depends only on the design of the diffuser and you can often see various defects like bright spots or a brighter zone at the edge of the screen where the lamp or the line of LEDs resides. Therefore, LED-based monitors can be both better and worse than lamp-based ones. It depends on the specific models.

Color gamut is due to the properties of the color filters of the LCD matrix and the backlight’s radiation spectrum. The 3-color backlight (red-green-blue) can ensure a really large color gamut with pure and saturated colors (you can refer to this review for details), but home monitors currently use white LEDs with a continuous radiation spectrum of a complex shape. As a result, the color gamut of such monitors differs but little from that of monitors with lamp-based backlight. I don’t say they are identical, but the difference can hardly be spotted with a naked eye.

Color accuracy. Obviously enough, the other aspects of color reproduction do not depend on the type of backlight at all. They are determined by how accurately the monitor is set up, by the monitor’s electronics, the characteristics of the LCD panel, etc.

So, although it would be wrong to claim that LED backlighting has no advantages, those advantages do not affect the image quality. The only indubitable high of LED-based monitors is their lower power consumption, but their image quality won’t be any better until the manufacturers switch from the white edge backlight to other technologies. And I have doubts that this will occur in near future because edge backlighting is cheap while the more advanced alternatives are far more expensive.

Summing it up, you should only deliberately look for a LED-based monitor if you care about power consumption. Otherwise, you should base your choice on other parameters, ignoring the type of backlight altogether.

how to buy new hardisk

A study of Storelab, a repair company data recently released important information about the age of the hard disk. Data collected in the long term, according to usage and damage the hard drive they found. This report is a matter of controversy because many defective or damaged disk made by the vendor manufacturers, and the importance of data stored on computer hard drive.



Computer users, especially the complete computer buyers never know what brand of hard drive they use. Sometimes a lot of buyers like the long warranty period, and ensure that their hard disk will be replaced if damaged. Damaged hard drive will be replaced, what about the fate of important data. Can be answered by the manufacturer of the hard disk.
Hard drive for home PCs may lose important data such as music or photo files into private collections. But for professionals, important data that made many months could have been lost by damage to the hard disk.

How long can hard working age. The answer is never the same. One vendor can generally reach 3.5 years, but there are others only up to 1.5 years. Capacity and model and distinguish the quality of a service life of a hard drive. About the hard drive maker manufacturer, the user, the percentage of damage and service life.

In general there are 6 major manufacturer of hard drive maker Fujitsu, Toshiba, Hitachi, Samsung, Seagate, and Western Digital. In research conducted more than 4000 hard disk unit with 3.5 and 2.5 inch format. Storelab perform comparisons of data collected according to the classification of products, brands and capacity and model.

According to iSuppli, the use of disks in the computer market. The world sales leader Seagate hard drive, followed by Western Digital.
According to data obtained from records Storelab damage the existing hard drive on them. Greatest damage occurred on the hard drive is Seagate's largest product who led the drive sales in the World. Almost 2X from the existing hard drive market share, equivalent to 31%
Although the use of disk in Russia amounted to only 40% of the entire hard drive Seagate brand. But the damage hard drives from other manufacturers are much lower, such as Hitachi and Western Digital are only listed 11% below it.

Designers such as hard disk drive maker Engineers may say they are capable of working hard for many years even decades. But the conclusion that they do is done on the basis of numbers, and not the actual test. Given a new hard drive may not sell after many years of trials conducted to obtain MTBF figures.
What is surprising from the data in the can by StoreLab. There was an old hard drive is only 1.5 years only. While the oldest works of Hitachi and Western Digital brand, able to work up to 3.5 years before the indicated damage.
From brand Seagate 7200.10 only type that is able to work more than 3 years. Samsung and Toshiba / Fujitsu also the same fate, only work within 1.5 to 2 years and into StoreLabs to do forensic data.

The conclusion of each hard drive data destruction

Seagate

* 500GB to 1.5TB Seagate Barracuda 7200.11 type. Achieve 65% of hard drive damage that goes into StoreLab to be repaired or saved data. The biggest damage occurred at Seagate 7200.11 Firmware damaged by displaying code 000000CC.
* Seagate 7200.10 type, more resilient than 7200.11. Damage only reached 35%.
* The damage occurred on the hard disk drive motor, especially on the axles. The greater the number of platters will shorten the life of the motor drive. And ends with the death of the hard disk.
* Hard drive that works excessively and continuously, into one category of causes of death drive. Signs of damage on the hard drive experiencing motor drives, hard drives will increasingly loud noises and excessive noise plus vibration.
* Seagate Technology hard drives trying to fix the 7200 series. And spend 7200.12 more reliable.

Western Digital

* 500GB hard drive turned out to hold up to 3.5 years. The remaining 41% broken is the type of construction.because 500GB platters more typically more vulnerable to damage. Even some models of damaged before the age of 2 years.
* Characteristics of damage to Western Digital is located when the process of writing and reading data on hard disk platter plate. That is the hard drive head is damaged, and become the hallmark of Western Digital hard drive.
* Other conditions are the temperature of the hard disk. Damage occurs when the hard drive has to work at a temperature of 45 degrees more. Hard drive becomes too hot.
* Western Digital makes hard drives with better shaking endurance. Creating motor shaft system is made separately with the cover disk. Do not ever close the hole on Western Digital hard drive. The unit, Western Digital hard drives are reliable. Including electronic and mechanical units used.



Fujitsu , Toshiba and Samsung

* Most of the models are checked for 2.5 inch format, especially the hard drive for notebooks. The average age of 2 hard drive manufacturer is reached 2 years.
* The most common problem on the Toshiba / Fujitsu is a pole clamp as drives in the form of a damaged bearing service life. Because the cover is very thin eroded, and the lubricating fluid evaporation occurs. This makes the friction in the socket, then rupture and destroy the axles.
* Other Damage occurs when the head drive start rubbing and damage the hard disk platter. Easy character, would sound like faint small sound. Then the hard drive will not be detected anymore by the computer BIOS. Certainly the data in the hard disk is unreadable, missing alias. It is generally a phenomenon at the Samsung hard drive.

Of the four major brands, best hard drive is Hitachi.


This was stated by StoreLab. 200 hard drive received and asked to be corrected to note this hard drive repair companies. And none of them have failed because of design work Hitachi hard drive itself.

* All the damage that was found was the fault of the user.

But do not make a benchmark that data StoreLab into alloys in selecting the hard disk. Because many other factors that are not visible to general public. Figures damaged hard drive can be smaller or larger view of this study conducted in eastern European countries, which are generally much cooler and the product is only marketed the country.

This figure is a collection and research conducted by StoreLab on damaged hard drive and tried to rescue the data carried by them.

Securing performance hard drive to work longer.

* Avoid hard work on high heat.
* Not putting hard work in bad conditions, such as the haphazard layout of the hard drive inside the computer or notebook.
* Using the anti-vibration components to protect your hard disk.
* If you need to pair the temperature sensors to monitor hard drive heat.
* Always provide a backup hard drive for data backup, if your data is important.
* Know the weaknesses of each product from the manufacturer.
