U disk shoddy recognition knowledge

It is indisputable that the U disk's appearance, to a lot of people bring mobile data application convenience, but the damage to the users of the fraud, the direct manifestation of the harm to the data. As a storage medium of U disk, if the chip and circuit board quality is low, light causes transmission speed drop, heavy loss of important data, loss is basically unable to quantify. A few years ago, due to flash technology limitations, U disk's maximum capacity has been around 1G, the price is relatively high. User requirements for capacity more than the performance requirements, but the sensitivity of the price to make fake products opportunity, so "capacity fraud" has become the most important means.

"I tell you, before 32MB polished fake 512MB is nothing at all, now make the most ferocious is 1GB, 2GB after the Polish directly fake 32GB, 64GB, or even 160GB products, sell a huge cheap, kill is greedy ' cheap ' layman." "Zhangxiaochi (alias) is a counterfeit U disk factory in Dongguan, the director of his daily work is responsible for the acquisition of U disk chip to rewrite."

The so-called rewriting, that is, some of the cottage U disk factory use of regular low-cost flash chips, through the special software to modify the control of the chip information, to the capacity of the larger purpose. In other words, the quality of the product itself and the previous defective, obsolete products, is definitely good, but the capacity is "unlimited amplification."

As for the modification of the control chip software, we often say that the "mass production tool", which is dedicated to the U disk's control chip to write operations, the original purpose is to write operations on the chip optimization and maintenance, and rewrite the motherboard BIOS principle is roughly the same. But after a special design of "mass production tools", not only can modify U disk capacity, but also the U disk's read and write performance for the temporary optimization, to the low-speed disk posing as a high-speed disk for the purpose of selling profits. That's the second way we're going to fake it.

Ordinary production tools are not complex, the general user through a simple teaching can be started. But the "mass production tool" of the fake workshop is specially designed, and its function is very powerful. Zhangxiaochi introduced, his workshop, one day can be "production" out of "128GB" U disk more than 5,000.
