Upgrade card with 1G (or a lower capacity) upgrades and virtual standard 4G.8G.16G.32G front 1G file copied into the actual available capacity is only normal use, that can be copied into the back of beyond, but the file is damaged and garbled, the most effective way is to use the H2testw expansion test software for overall efficacy Download.shtml the software by writing data to the directory being tested way to test disk write speed, and they read out the written data checksum is correct, read and write the memory block to determine whether the bad blocks.
TF card (TransFlash), also known as MicroSD, SD card, about 1/4, is the smallest, designed for mobile phones, small camera set
Prepared, GPS navigation designed removable memory card. TF card has all the advantages of traditional SD card with SD adapter can be converted into
SD card, and is compatible with devices using SD card complies with SD Association specification standards.
Computer display capacity: 29.6 g
Why U disk or flash memory card, the actual available capacity is less than the standard capacity?
Reason why flash memory cards, USB flash drives and other removable storage devices with a nominal gap is because the conversion asked
Problems. Hardware manufacturers in the production of memory chips by 1MB = 1000KB count, so production from
The actual capacity of 256MB of memory chips 250000KB windows system by 1MB = 1024KB account
Counted, so since the nominal capacity of 256MB of memory displayed in the windows should
250000KB ÷ 1024 = 244MB. Course, this capacity is not absolute, not according to the production process
The same, the use of different core, coupled with the system after formatting will have the system files take up space, so production
The capacity of the actual use of the product will be biased!
2.Mainstream capacity available capacity?
8GB actual available capacity is about 7.4GB | 16GB actual available capacity is about 14.8
32GB actual available capacity of approximately 29.6GB | 64GB actual available capacity of about 60G
