USB flash drive
August 5th, 2013
Well, I bought a 4GB USB flash drive yesterday, but for some reason it shows 3,73 I tried formatting it, but it doesn’t help.
Hope you’ll be able to help me.
its alright. 4GB pendrive showing 3.7 to 3.8GB. its perfect dnt worry about that.
Manufacturers class 1,000,000,000 bytes as a Gigabyte but Windows defines it by dividing the total capacity in bytes by 1,073,741,824, hence 4GB flash will show as yours has, 3.73GB.
The same as a 1TB Hard drive will only show as about 931GB
It's basically just a discrepancy with how manufacturers counts (in decimal) and how computers count (in binary).
Humans tend to use 1000 bytes = 1 KB, 1000 KB = 1 MB, 1000 MB = 1 GB.
Computers are binary so they use 1024 bytes = 1 KB, 1024 KB = 1MB, and 1024 MB = 1GB.
If you do the math, 4GB equals about 3.73GBs after you do the conversion.
