[clug] very FAT linux filesystems or cluster pixes?

With that sort of size variation, block size difference doesn't explain it.

I think either they may be showing the size based on total raw disk space
you use (if you are provided RAID volume etc) or by default there might be
some files/utilities occupying around 15MB space in the file system which
are hidden from the end user.
