Hi, I have a 40GB drive which reports its true number of cylinders to fdisk instead of 16383. From what I have read, >8.4GB disks can have more than 16383 cylinders, but should still report just 16383 because modern disks give their size information via a different interface. Either I have misinterpreted the standard or this is a non-standard disk. Either way, sysinstall complains during the fdisk phase that this drive configuration is 'impossible' and picks other values for the C/H/S info, suggesting that I put the geom in by hand during fdisk. I did the (g) option and entered in what I thought was the right thing 16383/16/63. The install proceeded and things seem to work. The reported size of the disk never changed through any of this. But I wonder, was the the right thing to do? Should I have taken the 4863/255/63 numbers that sysinstall suggested? I am not subscribed to this list, so please respond directly. thanks, -r
