You're mixing up units and prefixes.

In "km/h", "k" is the prefix and "m/h" is the unit.
In "Free bytes", "bytes" is the unit, not "Gb".

You're getting millions of Gigabytes.  I guess that's not right,
but that is because you instructed MRTG to do so.

The unit is bytes so set "Shortlegend[acs-sql.ldisk.freee]: B

If you're entering gigabytes into MRTG (in stead of bytes), the
default meaning of kMG (,k,M,G,T,P) has to be multiplied by
1,000,000,000 as well.  Basically the first three multipliers
are skipped (you don't do bytes, kilobytes and megabytes) so
do the same in kMG.

You'll have to look the rest up but here's the start: G,T,P,...
