Dear Managers,

i got a 73 GByte disk (ST173404LW) and the disktab entry from the dealer is
following:

st173404|ST173404|SEAGATE 73.4 GB Winchester:\
        :ty=winchester:dt=SCSI:ns#423:nt#24:nc#14098:\
        :oa#0:pa#131072:ba#8192:fa#1024:\
        :ob#131072:pb#401408:bb#8192:fb#1024:\
        :oc#0:pc#143122896:bc#8192:fc#1024:\ 143122896
        :od#0:pd#0:bd#8192:fd#1024:\
        :oe#0:pe#0:be#8192:fe#1024:\
        :of#0:pf#0:bf#8192:ff#1024:\
        :og#532480:pg#142590416:bg#8192:fg#1024:\
        :oh#0:ph#0:bh#8192:fh#1024:


but:

scu> show capacity

Disk Capacity Information:

                  Maximum Capacity: 143374738 (70007.196 megabytes)

                                                not 143122896

scu -f /dev/rrz40c show pages|grep 424
                 Sectors per Track: 424 not 423????? as above

now the disklabel looks:

# /dev/rrz40a:

disk: st173404
label:

bytes/sector: 512
sectors/track: 424

  c: 143374738 0 unused 0 0 # (Cyl. 0 - 14089*)
  d: 16006848 20138304 unused 0 0 # (Cyl. 1979 - 3551)

  f: 22000512 62155008 unused 0 0 # (Cyl. 6108 - 8269)
  g: 0 0 unused 0 0 # (Cyl. 0 - -1)
  h: 0 0 unused 0 0 # (Cyl. 0 - -1)

which one of this entries is true???

                                Thanks, H. Baumgartner
