The total and used/free space in ext and FAT filesystems can be computed from the output of tune2fs -l/dumpe2fs -h and fsck.dos -n.

all my disks have "msdos Partition table".


Debian thought it relevant enough to mention in a warning(error?) message. There I thought it reasonable that it was true of _all_ my disks.

  I get the following error message:
root@fromdell:/home/richard# tune2fs -l /dev/sda

You must specify the partition containing the filesystem, not the whole disk.

The man pages for fdisk, parted, sfdisk, tune2fs, and dumpe2fs each give "device" as a possible parameter. Only the last two balk at it.
