I can't understand it. I formatted my external hdd and flash drive and they're still with some space used, how?

OS: Windows 10 x64 up to date.

Health of the drives 100% cheked by crystaldiskinfo.

"First is that hard disc manufacturers quote the capacity of their decimally, where kilo=1,000 (and mega=1,000 kilo etc), whereas operating systems usually use the ‘binary standard’, where kilo=1024 etc. On large modern hard discs this can amount to quite a difference.

Secondly, formatting discs involves creating a filesystem – a way of organising the files and folders on the disc (a bit like having table of contents, page numbers and indexes in a book), and this uses up some space. Depending on the filesystem, the amount of space can be considerable.

All perfectly normal.. Think of that space as your file cabinet. There has to be a structure for you to put your files in..

What Burpo said, plus, NTFS reserves space for its overhead. The default reserved space is approximately 12.5% of the actual drive volume.

Yeah, the first one i already knew and i didn't know why until today they insist to not "be on binary system".

The second one is my question as i've never paid attention that even a formatted drive would have that amount of "used space".

About that fileystem, it doesn't create any real files on the disk, right?
