why is my 4 GB sandisk cruzer blade showing only 1.07 GB as free space while 2.65 is used. But I have removed all data from it. only some pre loaded data is on it which i THINK is the security and all of the flash drive
If you look at the fine print on the packaging of HDDs, SSDs, flash drives, etc, you will see that it says how the number is calculated based on 1GB = 1000MB, so basically they use a base 10 system. Your computer uses a base 2 system, so it's actually 1024MB to 1GB. What you're basically seeing is the difference in calculating 1GB using base 2 and base 10 math.
