new formated HDD noob question

[iChip]

Hi, just bought new drive once it was formated and I went to check properties and it already has some "used space" which is around 150MB even tho I just formated it (Using this drive as storage and I did not copy anything there just yet) so Im wondering why does it shows 150mb in usage?
+ its not fully the size as the manufacter said its gonna be but as i have been reading some stuff I assume its normal, is it? Thanks

The data that comprises the file system requires some space. 150MB is perfectly normal and nothing to be concerned over.

As far as hard drive sizes go manufacturers use 1000MB=1GB whereas the rest of the world uses 1024MB=1GB. Either way you get the same amount of space, it's just a difference in the units used to report it.

This comes from two reasons:

1. PC's are designed by engineers but sold by marketing majors ( aka expert fibbers) . In the digital world, a TB id 1024 GB..... to a marketing person, it's 1,000 GB supposedly because the consumer finds multiples of 1024 confusing. It's only been confusing since the late 1990s when marketers led the charge to "redifine" the accepted definitions.... by the time we multiply the 1.024 factor for kilobytes, gigabytes, terabytes etc ...

Ya lose about 7% when thinking in Gigabytes
Ya lose about 9% when thinking in Terabytes

2. We lose more space to the typical 100 MB EFI system or reserved partition in modern OS's and to the Master Boot Record which is basically the index of where all your files are
