Ah, you were cheated by Andre.
In the good old days `hdparm -i' gave interesting output.
These days `hdparm -i' prints not what the disk says, but
what the author of the IDE driver thought you would prefer to see.

So, `hdparm -i' is completely worthless (for geometries) these days.
That is why I asked for `hdparm -I'.

Let me predict that it will say

# /sbin/hdparm -I /dev/hdc

/dev/hdc:

Model=aMtxro9 71828D, FwRev=AG5S1421, SerialNo=8A501SCX
Config={ Fixed }
RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=29
...

and hence is not an exception. It really tells the world
that it is 16383/16/63, entirely according to the standard.
