Its time for disk geometry games. Its been a while since I worked with disk
geometry but its not really that bad. In fdisk select (x) and press m. Notice
the following options ( c, h, s ). You'll have to work with these settings to
get your system to see the whole disk. I seem to remember that you basically
multiply c * h * s ( as listed in your hd specs ) which yield a particular
number. You then change the values of the c, h and s, in fdisk, to yield that
same number or as close to it as possible.
The problem comes from a value in the disk geometry structure in the kernel.
It seems that the values for c,h and s are short ints and your disk has more
cylinders heads or tracks than will fit in the value held in the structure.
Its been a couple of years since I dealt with this so if anyone else could
chime in now would be a good time.
