BUYER READING :
Just buy 4 gb TF card such as a user, when connecting the computer, the computer shows that this card has a capacity of only 3.8 G. The name users expressed bewilderment: clearly marked on the memory card capacity of 4 g, why I spend money to buy back the capacity of nearly 200 MB gone? The 200 m is enough to hold 50 or more songs, is this product quality problems or vendors to deliberate? Users can find carefully, not only in the memory card will appear such circumstance, in the U disk or mobile hard disk will appear such circumstance, a marked 250 gb hard drive, often on the computer shows that only 233 g or less. In fact, it is not the manufacturer's fault, for this kind of situation is there are many reasons, combined the main reason:
(1) the calculation methods of error
Storage devices used by manufacturers in nominal storage capacity base is 1000 to 1 k, and the operating system because of using binary relations, formatting software occupies space after hexadecimal is 1024 to 1 k, it will make use of storage space look is much less than the actual. Such as:
Storage vendor standards:=1,000KB
Algorithm of the operating system: 1 MB = 1 KB = 1024 byte 1024 KB));
Questions about capacity of these are normal: 128000000 present 1024 present 1024 = 122.0703 (MB)
Such as hardware nominal 128 MB MP3, identify capacity is converted to software
128 MB (1000 KB / 1024 KB = 125 MB, so there will be 3 MB calculation error.
(2) the internal file takes up space
After the partition and format, the system will take up some space on the hard drive, provide for the use of system files, like hard disk, usb flash disk is the FAT file system, and the FAT file system includes the MBR boot partition, FAT file allocation table and ROOT area, etc., these areas generally takes hundreds of KB flash memory space, so the operating system according to the total capacity and model in the capacity of hard disk is different this is a normal phenomenon.
In addition, due to the problems during manufacture, flash chips allow a bad piece of flash memory medium (BadBlock) the existence of these bad block can not be used, nor exactly effective capacity. That is to say, the manufacturer is not the same conversion method and computer, the one is U disk system space to a certain extent, cause you U disk is smaller than the actual!
1000 gb / 1024 * 1000 = 976.5 MB and system files, so 970 m or so is very normal!
by parity of reasoning
Around 2 GB = 1.8 GB
About 4 GB= 3.6 GB
Around 8 GB = 7.4 GB
About 16 GB = 14.8 GB
That's enough card shows the actual capacity of! Hope I won't be in the evaluation of the words, why only 2 gb memory card capacity 1.8 GB
