Since U disk in the production process

Since U disk in the production process, in accordance with industry practice, all the U disk capacity must be fixed. Because 1G = 1024MB to address non-integer conversion of all businesses will be translated into solid solution U disk 1G = 1000MB. Thanks to the solid content of this "gap" caused so many unscrupulous businesses will upgrade the U disk against the public interests of consumers.

 

For example, U disk capacity: 1G U disk capacity can be fixed capacity for the 2G or 4G or 8G, etc., 1G U disk capacity of computer property after solid solution appears as 2G or 4G or 8G, but the actual available capacity is 1G.

 

This excessive solid content of the U disk is the industry and consumers, respectively, and fake goods that U is an upgrade disk. U disk test software is based on the Silicon Valley, U disk considerations of consumer interests and development of the birth of the U disk quality test products. U disk bad block is whether the chip U disk storage security key! Bad chips as U-disk can store file data, but there is a higher storage risk.

 

Hazards of bad blocks:

 

First, you can copy the file to write U disk, but read data error, which is just as well copy the data to place a chip due to bad blocks.

 

Second, you can copy the file is written U disk, data loss suddenly dropped, because the chip where there is a lot of bad blocks and the chain reaction of damage.
