Unraid Showing Much Higher Disk Utilization than Windows [Solved]

[SergeantCC4]

Currently running 6.2.4 stable (setup A) and have been in the process of moving over my drives from RFS to XFS. I have a secondary setup also running 6.2.4 stable (Setup B) and I dump all the data from a specific disk to the other (A-->B). When it's done, I stop the array switch the disk to XFS and start/format the disk.

Now the strange part is that when I go to move the data back from B to A, windows says, for example, that the size on disk is 2.55 TB. However in Unraid on the webUI the "Used" size is showing as 2.81TB.

 

Now usually if it were a small difference I would be ok with it. Take it as some fluke, but nearly 300GB difference I'm having some hard time swallowing....

 

I've attached the pictures describing what I'm talking about, and if anyone could help I'd really appreciate it...

When Windows showing the free space, it takes 1k=1024bytes, 1m=1024k,1g=1024m, 1t=1024g, hence the used space is 2806394044083/1012/1024/1024/1024=2.55, while Linux takes 1k=1000, 1m=1000k an so on, so the used space is 2.81. It's just different in displaying.
