But it works fine. Except that the optimizations offered by the UFS file-system are not much needed with modern SCSI disk drives which have physical parameters far from being constant in term of sectors / tracks so it is better to let the controller do the work and use the translated geometry... -- Ollivier ROBERT Ollivier.Robert@keltia.frmug.fr.net A FreeBSD & PERL addict...
