Hardware damaged

Xu Yi and Yan Yu played out in the network arena in time, ANSG office is raged. World War II had just experienced a hacker, not only did not get any useful information, people catch up with the headquarters also will get three days the computer get on the ground. Which has always been invincible ANSG encountered this situation? The past, no matter how difficult the task, if the other team get it working, as long as the head of Kevin a hand, will be completed. This time, the situation is greatly beyond their expectations, team leader at the last moment and shouted, "Shut! Immediately!" Of Christ also echoed in front of them.

"Head Why is that? He ... ah ... he was, but Kevin! He Is not invincible it?" The spiritual leader of the world of hackers, hacking the eyes of God we, we never expected him too badly, embarrassed to turn off the computer only to escape the destruction of opponents.

Kevin The performance is disappointing, although we all know is very powerful opponents, but Kevin has been broken the myth of invincibility, although everyone did not say anything, but Kevin's position in their hearts already shaken. "So is our captain and also as ah." Members have the hearts of such a Si Ming Wu.

At the moment, Kevin is hands across their chests, waiting for that three men were on the test results of the computer problems, deep eyes and stared at a computer monitor which I do not know what the thinking.

Check out the results soon, is, as expected, and Xu Yi, two computer hard drives had some damage to the sector, the other with self-test is a computer problem, which means a problem with the computer's motherboard.

This result is undoubtedly very alarming.

If the former, who was said to be in a short time through the network computer hardware damage, and that no one will believe them. But now, a living example in front of them, they have to admit that this conclusion is yes.

We are aware of each other's terrible, it shows that he is not only well-versed in network technology, but also very understanding of the underlying hardware. They have speculated the other is how to do this.

"I know how damaged the hard disk." Sat before a computer which checks Kane drone to speak. Everyone's attention was immediately attracted to their eyes focused on him, they all know deep Kane studies in this respect, and only he can find the why.

"In fact, his approach is also quite simple, it is kept to format."

"Kane, formatting can also damage the track it? Format if not does not really delete the above file? Disk file structure information is also stored in the above, and even a thorough format, only the equivalent of the above 0 or 1, all of the information re-covered again it will not cause any damage to the hard drive, right? "Si Duoti out of his own questions.

"Ah, the usual format is this. You say this format is a high-level formatting. You know, the disk format can be divided into high-level formatting and low-level format, the two are different."

We all know there is such a low level format, but usually have never used this function, they are often ignored by, their functions are not well understood. Several people were exposed expression dawned.

Martin said: "So is the low-level formatting ah!"

Kane nodded: "low-level format, also known as the physical format, its role is to empty one disk divided into concentric circles of different radius, track, track will be divided into several sectors, and in each The physical sector address information marked regional court, which is similar to playing in a white paper on the same grid. usually played on the disk before the operation will be completed by the manufacturer, so buy the hard disk, we do not use the format direct partition, and then advanced formatting. and the life of low-level format the hard drive there is a huge influence, as long as the short period of time, repeated the same low-level format the disk sectors, this sector will soon be damaged. You see, "Kane display only the results of the disk check said," where bad sectors starting from 0, then 1, so go off if you do not stop, the entire hard disk will be scrapped. "

Sure enough, all the disk checker to see the display shown in the results, as Kane puts it, all nodded, may have in mind in considering the next time also used this method to deal with against other people.

Kevin on Kane nodded, apparently agreed with his argument. He also knows that low-level format the hard disk will have an impact, but never thought to use this feature to the computer damage.

See Martin, head of staring at the third machine looked for a moment, frowning, shaking his head is nodding again, and then asked: "leader, you know where the machine is damaged it?"

This third computer obviously much more serious than the other two, even the self is not normal, it can be said to be truly scrapped.

Kevin did not directly answer, but is instead asked his head around a bare body fat kid: "Michael, What do you think?"

"Team leader, I guess, not board scrapped, it should be the issue on the motherboard BIOS, the other contents of the BIOS to change the inside, so the system can not start." Of course, Michael knows that if an ordinary Internet users encountered this situation, it is the equivalent of board scrapped.

Kevin nodded again, agree with him.

BIOS stands for ROM-BIOS, which means "read-only memory input \ output system", it is a small program to deal with specialized and computer hardware resources, but this program is not stored in the hard drive, but directly in a curing chip, regardless of power or electricity, it will not be lost. Therefore, it is read only, the key point is to "cure" word, usually does not change. But this time, it was changed!

As if to prove his point, Michael started working on the motherboard BIOS upgrade program. Although BIOS is read-only, but there are ways to modify the major motherboard manufacturers have proprietary BIOS upgrade, but some problems may start from a floppy disk, using special procedures to upgrade. Michael ready for the machine in the same motherboard BIOS upgrade, you want to re-"refresh" inside the BIOS program, but found the process damaged the original BIOS, this method can not successfully upgraded.

But it's still way Michael. He got a compatible FlashROM "writer" (the stuff you can burn the program into the chip), the BIOS chip on the motherboard that buckle down, and then burn into the upgrade process, and then plug it back chip , connected lines, the system started really well.

The reason is clear, but, in the end how to come through the system BIOS software to operate it? They may have never heard of such a BIOS can also modify the.

After three computers will be repaired, we will be scattered, Face your heart, what happened today is too much shock to them, and this thing just for them is a great shame.
