[SOLVED] After formatting SSD lost space

[psy1]

Just as the title says: After formatting SSD lost space

Here's the story:
Had my Win10 OS on my Samsung 960 Pro 512GB.
Something went wrong so I had to format the SSD.
Now that I'm ready to re-install the OS on the SSD I notice that the space is dramatically lower than it should be. (Probably due to the harsh formatting programs I used.)
Original size of drive = ~512 GB, Size after I formatted = 476 GB, Missing GB = 36

Sure you could argue that the missing GB is used for important stuff to keep the drive running, but 36GB is too much.

Here's a screenie from WinDrStat:

Notably, Samsung Magician reports that there's 111MB of used space on the SSD.
I'd love to get the original size back, if I can recall it was around 500GB with all the Samsung stuff on it.
BTW Samsung Magician's 'secure erase' doesn't restore the lost GB. It appears when I formatted the SSD most of the functions of Samsung Magician were lost. I would also like to retrieve those functions.

You can see the capacity in properties is listed as over 512GB.
Oh I see now, it says free space: 5112,092,008,448 bytes. But how does that equate to 476GB?
Oh I understand now it's the stupid 1,024 bytes per Kilobyte thing, it trolled me again!!

OK that's my problem solved sorry for wasting anyone's time.

Yeah, there's the problem.
In order to (over) simplify estimated capacity of drives, suppliers will use 1000MB=1GB and 1000KB=1MB, whereas infact it is 1024MB/KB etc instead. As a rule of thumb, I would expect any drive i buy to lose about 10% of the stated capacity for file indexing/management software built into it.

All in all, 476 from a "512GB" SSD is about average bud.

"Original size of drive = ~512 GB, Size after I formatted = 476 GB, Missing GB = 36 "

That is not missing space.
That is merely a byproduct of different measuring units.

Base 2 vs Base 10
Computer vs Human
1000 vs 1024
Reality vs Marketing

ALL drives are like this. You have lost ZERO space.
A "1TB" drive will read as 931GB
A 500GB drive will read as 465GB
A 512GB drive will read as 476GB

There was even a lawsuit about this many years ago. This is why there is little tiny print on the box, telling you this.

Suit alleges companies misrepresent capacity of flash memory devices by using decimal definitions, thus overstating memory card sizes by 4 percent to 5 percent.

Base 2 vs Base 10 notation. Hard drive manufacturers use base 10 notation (1000 = 1K), whereas computers use base 2 (1024 = 1K). Nothing is actually gained/lost, it's just a difference in notation.
