Thank you. But how do I known parameters of existing filesystem? disklabel ad0 shows, in partcular: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 102400 524288 4.2BSD 0 0 0 # (Cyl. 32*- 39*) b: 524288 0 swap # (Cyl. 0 - 32*) c: 12594897 0 unused 0 0 # (Cyl. 0 - 783*) e: 3072000 626688 4.2BSD 1024 8192 22 # (Cyl. 39*- 230*) f: 1024000 3698688 4.2BSD 0 0 0 # (Cyl. 230*- 293*) g: 2048000 4722688 4.2BSD 0 0 0 # (Cyl. 293*- 421*) h: 5824209 6770688 4.2BSD 1024 8192 22 # (Cyl. 421*- 783*) How do I know real parameters of 'f' and 'g' partitions and why zeroes are there?
