I've got this 64GB microsd card as external memory in my android tablet. When formatted in FAT32, it shows only 59.45GB available besides a 32Kb 'lost.dir' file.
So what happened to the 4.5GB that seems gone ?
Would another file system improve this ?

THANKS,
V.

HTG Explains: Why Do Hard Drives Show the Wrong Capacity in Windows? - How-To Geek

It comes down to how the space is calculated by the manufacturer and by how memory is actually calculated.

Computers work with bits.. 1's and 0's... so space is sort of calculated the same way. 256, 512, 1024, 2048, etc etc.. (those all must look familiar, like I don't know, thumb drive sizes over the year)

So hard drive manufactures and others calculate space in powers of 1000. The box says 64 GB but in actuallity its not..

1024kb =1MB
1024MB= 1GB

64*100*100*100= 64000000000 bytes by their logic

64000000000 /(1024*1024*1024) = 59.6046447754 GB

yay math



So all of your space is there, it's just advertised incorrectly.For you to truly have a 64GB capacity its sort of impossible, the next step up would be 128GB due to the power of 2 or something, I didn't really pay much attention to that in my intro to comp sci class since I already knew how to convert bases and what not.....Also some space is lost to formatting but not much.


(now do it all in Binary, convert to base 19, and then convert to hex )

Advertised incorrectly?

Is this proof that the glass is always half empty and not half full?

Clk's Ebay Stuff BUY SOMETHING NOW!!!

Well it makes it easier for the consumer to understand at they are buying,plus the packaging usually displays this info.

That doesn't really solve anything, in fact it just makes It more difficult. Macs still operate in machine code just like windows.

having owned two macs, one notebook and one desk top, i can i say i will never own another. theyre beautiful, but built like ****, and few parts are user replaceable.
