Manufactureres sell 8,000,000,000 Byte drives as 8GB

So
7812500KB
7629MB
7.45GB

7.45GB is all you get on an 8GB stick.

If you think that is short changed, I recently bought a 1TB external HDD which max's out at 931GB.

I think what it is, is that vendors call 1000KB=1MB instead of 1024KB=1MB and so on.

More info on storage capacity measurements here....It's a bit of a con/ marketing trick, sellers use decimal, we use binary.

I get that on the Cruzer Edge sticks that I buy but there was even more on the Seagate 1TB external drive which I got rid of by formatting it.

Hi, I think 4 gb is enough, but 8 g b , i prefer.
                                                You should format before doing that. You have to insert some cmd commands to do before you do that.
The Bottom line is "Check your hardware first if it supports the task you try".

Easy way I can think of is windows uses base 2 file size count.

If windows was to switch over to base 10 file size count you would see a bigger size usb.

so if windows had base 10 file size instead of base 2
you would download a file thats 230 mb from the internet and when you look at it on your usb it  would show up as 250mb instead. kinda weird eh?

Base 2= binary (0 and 1)
Base 10= decimal (0-9)
Base 16= hexidecimal (0-9 A-F)

Windows use hexadecimal because the memory addresses are so large.

When I created a bootable USB using Windows USB/DVD Burner Tool, I was prompted to format it first to NTFS, but I noticed in the link JR has posted that Diskpart formats it to FAT32.

Hi,  Boggins,
It will format automatically to NTFS. That is what i know of . But there was no problem. The tool is entirely different.
                   here we do not use any tool , but some cmd commands and total copy. Whereas usb dvd is set tool for this purpose.
The Bottom line is "Check your hardware first if it supports the task you try".

yeah this wired and I hop there is no hiding adware/malware into my USB flash drive  :cheesy: that will using that space like laptops vendor already do that into it

and do I need to format the new USB flash drive? If yes , which format type I need to go ?

I created my bootable USB directly from the ISO and not converting from a DVD which is probably why I was prompted to format to NTFS first.
