disk geometry confussion

[piotr.smyrak at heron.pl]

Hi,

I had a disk failure recently, and bought a new drive afterwards. it 
is 80GB WD800BB model. I went on with a fast install to restore my 
ability to work. I created a small slice in the leading gigas. Now I 
wanted to go on with slicing the disk, but I got stuck.

When I get to sysinstall's fdisk I get a warning that my geometry is 
incorrect and an explanation as follows:

<quote>
you need to enter whatever your BIOS thinks the geometry is!
For IDE, it's what you were told in BIOS setup. (...) 
_Do NOT use phisical geometry._
</quote>

The BIOS recognizes my disk as: 38309/16/255. The fdisk when started 
claims 155061/16/63 is wrong, when I follow and press G to setup the 
correct values, it presents me with 9729/255/63. I tried all of 
them, but I always get the incorrect geometry message and whenever I 
try to write changes to disk, I get: 

<quote>
ERROR: Unable to write data to disk ad0
Disk partition write returned an error status
</quote>

OK, so here it states smth contrary to the sysinstall warning:

...that I should follow with disk CHS values. I got them from WD 
site (16383/16/63), and these are the only ones fdisk do not 
complain when entered, but! it is the contrary to what the fdisk 
warning states when run:

<quote>
(...)
_Do NOT use phisical geometry._
</quote>

Please enlighten me. What way I should follow? 

TIA,
