You do not want to calculate block numbers in any old way when you make slices, just offset and size.. You do that a little when you do disklabel. The cylinder, track, sector values are virtual on mondern disks and do not map directly to the disk's actual cylinders, tracks and sectors - at least for SCSI drives and so you don't want to mess with them. Let the system (fdisk and the disk controller) deal with them. ////jerry > > -- > Chris Christoph P. U. Kukulies kukulies (at) rwth-aachen.de
