My guess is that 5.4TB is larger than the maximum partition size that
can be reported in DiskPartitionStats and you are therefore seeing a
partition used calculation that is inaccurate.
The DiskPartitionStats for free blocks, usable blocks, etc. are reported
as a 32-bit signed integer with a block size of 1K. Effectively
anything larger than 2TB is going to give inaccurate results.
A 5.4TB partition will therefore appear to be a 1.4TB partition which is
what you see reported below.
