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: 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._ 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: ERROR: Unable to write data to disk ad0 Disk partition write returned an error status OK, so here it states smth contrary to the sysinstall warning: http://groups.google.com/groups?hl=pl&lr=&selm=3ee36290%241%40news. broadpark.no ...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: (...) _Do NOT use phisical geometry._ Please enlighten me. What way I should follow? TIA, -- Piotr Smyrak piotr.smyrak@heron.pl
