Hello, I noticed a discrepancy recently regarding a partition of mine that I installed Ubuntu Studio on.

According to Gparted, it shows that the partition that it's installed on reads 652.71 GB total compared to what it shows on the desktop.

On the desktop for that same partition, it reads 701 GB as its total size. Which program is reading the partition size correctly?

I forgot to clarify with some screenshots earlier.

Both Disk Management and Gparted read 300GB for the Windows partition and 630GB for the Ubuntu Studio partition.

Testing out Ubuntu Studio from a live CD image, it reads 323GB for the Windows one and 676 for the Ubuntu one.

300.88GB+630GB+529MB+100MB = 931GB.
Exactly what a "1TB drive" should read in Disk Management

I found out that Disk Management reads in Gibibytes (GiB).

The Windows partition reads 322 Gigabytes on Ubuntu Studio, and the same partition on Windows through Disk Management reads 300 Gibibytes.

They are the same thing.
322 gigabytes is the same as 300 gibibytes.

But for some reason, Windows incorrectly reads it as GB (gigabytes) instead of GiB (gibibytes).
Why is this?

The label in Windows is gigabytes. "Gibibytes" would sound too geeky and confusing to the masses.
