Bought a B2 with 1TB disk and after logging in for the first time the info on the home page was:
Total disk size 928 388 MB
Free disk space 881 023 MB
The difference is 47 365 MB -> ~47 GB.
Isn't 'Total disk size' the maximum available space for data on the disk? Of course there is some space required for FAT and similar but shouldn't 'Total disk size' be 'Real Disk size' - 'file table size'?

Preinstalled 1T disk but with 47GB free space diff
This is a combination off several issues actually, which can give the impression that there is a large difference.
First we have partition and filesystem metadata including journaling data which tales up a small amount.
Second the hard drive is divided into three parts, first we have the root partition, which is 10GB; Second, we have the swap partition which is 1 GB; This total to 11 GB.
Third is that the home partition is an lvm-partition, which include some additional overhead
"Total disk size" is the total disk size for the home partition actually, and "Free disk space" is that is available at the moment on the home partition.
I hope this answers your question.

Yes, of course, but I suppose there is information how much space that is available for storage. At least dos/win/mac have this so I suppose even linux have this.

Maybe each partition could have their own "total" & "free" disk space indicator.

Same comment as in Note 1.

There's another factor. By default, ext2/3/4 partitions have reserved space for a user. You can discover how much reserved space is allocated for a partition by issuing the following command:
Where /dev/sda1 is the partition in question.
Code: Select all
tune2fs -l /dev/sda1
