Yes, there are invisible buffers, but the discrepancy doesn't come from this. Drive makers count the space in 1000 -multiple units (i.e. 1GB = 1000*1000*1000 bytes) whereas in computing units are usually count on 1024 -multiple (i.e. 1GiB = 1024*1024*1024 bytes)

So 1TB = 1000*1000*1000*1000 bytes/1024/1024/1024 = 931GiB (or 0.9TiB)

Did you notice the part where I explained how drive makers use the decimal units but the chips they source to build those drives are built in binary capacities?

I don't give a shit whether your operating system likes to show you disk usage in binary or decimal units, because I'm not talking about software at all. I'm explaining how the hardware is built. I especially don't need another person to try to explain what the binary and decimal units are, after I've repeatedly used both correctly.
