Just got a new Sandisk Ultra 2. Supposed to be 960GB, I understand it normally comes out lower - but 70GB lower? Got to be something wrong surely? The disk is unallocated. All I;'ve done it initialise the disk through windows partition manager.

Easeus partition manager also shows 894GB. Ideas?

Thanks,

Alex

That is exactly what it should be showing.
Gigabytes vs Gibibytes.
Base 10 vs Base 2
Human vs computer.

The bigger the drive, the bigger the difference.

I have a 2x 4TB and 1x 3tb pooled together (meaning shows as 1 large drive), and together my REAL space is only 10TB.

HDD/SDD Drive manufactures use gigbyte to mean billion bytes, so 960 GB = 960 billion bytes.
A real gigbyte = 1024 megabytes which is 1024 kilobytes which is 1024 bytes.
So 894GB * 1024 MB * 1024KB * 1024B = 960 billion Bytes.
