On my newer XP disk images, fdisk seems to report correctly the number of heads 
and sectors but fails to get the number of cylinders and complains with a "you 
must set cylinders" message.
On my older images, it doesn't seem to be able to guess anything.
Hdparm -g exits with a "Value too large for defined data type" message in both 
cases.
