Now that the problem has appeared, Yao Dong immediately began to investigate and solve the problem, for the investigation of computer problems, as long as there is a little common sense, you know that the road is generally carried out according to the method of first soft and then hard.

Just like if the current computer is not working normally, the first thing we should think about is whether it is the loss of a certain associated file, which leads to the corruption of the entire software and makes the computer unable to use normally.

If the problem persists after doing the above steps, then we should consider whether there is a problem with some aspect of our computer system.

This is still not difficult, find a software with system repair to repair the system, or redo the system can also be judged, which is why many people say that the computer system card, the computer is not broken, and it can be used normally when someone else helps you redo a system in the computer store.

If the problem persists after the above two methods, then congratulations, you have won the lottery.

Since the fault of the software part is eliminated, we need to judge from the hardware aspect, but this is generally powerless for users, and the hardware repair process is as long as a 28,000-mile long march.

Just imagine those days when people who like to surf the Internet every day but can't be on the Internet for a long time, which is even more uncomfortable than breaking up with the other half in love.

And even if it is beyond the warranty period to get the computer repair shop in the time it takes is not short, and you have to pay out of your own pocket, it is better to meet a conscience store, you will consider yourself unlucky when you encounter a black store, even in that era when information is very developed, not many people will find the price of the model of hardware on the Internet, and even if you find it, people have 100,000 reasons to fool you, that is, how to think you don't understand the computer......

Problems with the computer software can be ruled out because other files as well as programming programs can work properly.

After that, the problem of computer hardware was also ruled out, because when Yao Dong took a new floppy disk to experiment and write, it could also be entered normally.

The problem has become very obvious now,It's out of the floppy disk,This year, the most used floppy disk is5.25Inch floppy disk,Although Sony has taken the lead this year to launch a smaller size、Larger capacity3.5Inch floppy drive and floppy disk,But now it is not accepted by some major PC manufacturers,The popular one on the market is still 5.25Inch floppy disk,The United States does not buy small Japanese accounts at all。

It wasn't until April 1987 that IBM launched the 386-based IBMPersonalSystem/2 (PS/2) personal computer series, officially equipped with a 3.5-inch floppy drive, that it attracted a lot of attention.

Everyone is attracted by this new floppy disk that is smaller in size, but the capacity is several times that of the 5.25-inch floppy disk, since then, under the strong recommendation of IBM, Compaq as the representative of the manufacturer, this 3.5-inch floppy disk began to become popular, 3.5-inch floppy disk with its cheap price, The relatively huge storage capacity (1.44M, million bytes of storage) soon occupied the market, and the 3.5-inch floppy disk drive also began to officially replace the 5-inch floppy drive as the standard configuration of the PC, heading for the most glorious period of its life.

This absolute monopoly lasted for more than a decade, until 2002.

At this time, the floppy disk is not like the U disk we use in later generations, can not be used normally, but also can use the computer's own disk detection and repair tool for detection and repair, it is really not possible to use it again if it is ruthlessly formatted, only a few defective products because of their own quality is not up to standard, it will not work twice, I believe that some students who are greedy for cheap and have bought 8G on the stall as long as 15 or 20 yuan U disk have suffered such a loss, often can be used at the time, buy it back and use it a few times to break, these are actually defective goods.

And what about floppy disks in these years, if they are broken, they are broken, and they can no longer be reformatted, either you risk that the huge floppy disk may strike at any time and continue to use the tracks that have not used the damaged sectors, or you have to replace the floppy disk with a new one to work.

In short, this year's floppy disk has all kinds of faults and drawbacks, large size, poor quality and easy to break, must be formatted before use, and small capacity, which may be an incomparable headache for others, but for Yao Dong, this is undoubtedly the inspiration for him to get rich quickly.

Floppy disk is actually the predecessor of the hard disk and U disk in a sense, it currently replaces the position of the hard disk in the computer, in addition to the computer instructions pre-stored in the processor, the files and programs used by people are undoubtedly stored on the floppy disk.

The manufacturing technology of the floppy disk itself is also very simple, in principle, a floppy disk is divided into a number of tracks, each track is divided into a number of sectors, and each sector stores 512 bytes.

The track is a set of concentric circles, a track is about a few tenths of a millimeter wide, and the data is stored on these tracks, take the single-sided 360KB floppy disk that Yao Dong is using now, it has 80 tracks, each track has 9 sectors, and only one side can store data, we can calculate its capacity like this: 80×9×512≈360K.

In terms of manufacturing technology, a floppy disk actually consists of only two parts: a thin plastic disc coated with magnetic material, and a protective plastic envelope or hard shell.

After thinking about this, Yao Fei taught the principles of floppy disks and the general manufacturing techniques to Gong Yun and the bearded Abt and their group, and Yao Dong continued to be the shopkeeper.

If you make it so clear that they are useless and can't produce tangible results, then you should really send them to the Sahara, where birds don't poop, to farm.

More than half a month has passed, and after digesting the knowledge they have instilled in them, these people have lived up to Yao Fei's hopes for them, and the floppy disks with the same functions on the market have been able to produce themselves.

Moreover, it has overcome a very key technology, that is, by improving the reading and writing operation of the floppy disk drive and the manufacturing technology of the floppy disk, the floppy disk produced by Feiyue Technology Company does not have to perform the formatting operation before each use, so that it can complete intermittent operation on a floppy disk at any time, without the need for continuous backup as before, which not only greatly facilitates the computer user, but also greatly improves the work efficiency of the computer user.

And it also saves the cost of floppy disk users, you must know that the floppy disk in this year is still very expensive, and the worst is to start at more than ten dollars, unlike the later generations like dozens of dollars can buy how many G capacity U disks.

Next, just wait for Xerox's inkjet printers to sell well and start mass production immediately, what is lacking now is start-up capital, and when there is money to build a floppy disk manufacturing plant, the only thing left is to slowly improve the production process.

This is not something that can be solved overnight, even if it can be solved, Yao Dong does not want the products on the market to be broken, which is completely inconsistent with the law of market development, and the launch of products is still more stable and in line with their own interests.

If you immediately make the USB flash drive a bad street, let's not discuss whether there is a USB standard interface use in these years, just how many generations of products produced in the middle of it have to make less money from this world.

Everyone earns money, if you really dump other people's N streets, and serve your own broth, you will cut off other people's lives, and it is still unknown whether you will have a life.

Although it is a legal society these days, there are still a lot of privileged classes, Yao Dong doesn't even have the power to protect himself now, it is better to keep a low profile, and it is better to make a fortune as low-key as he can be.

As for the future, let's talk about it later, when I have the strength to protect myself and am not afraid of the threat of anyone or even any country, then I can go the way of others without any scruples, so that others have no way to go......
