My disktab states that rz55 have the following parameters:
rz55|RZ55|DEC RZ55 Winchester:\
:ty=winchester:ns#36:nt#15:nc#1224:\
:pc#649040:bc#8192:fc#1024:\
ns*nt*nc gets a totals of 660960 sectors which is not equal to pc#
(649040), a difference of 11920 sectors.
What are the correct parameters for this kind of disk ? How can I
utilize the whole of it ?
Can I connect the disk to Suns workstations (scsi), any one has a
format.dat entry for it ?
Tnanks in advance,

That's right.. But there are 10300 spare blocks according to the book, so (ns.nt.nc) - 10300 = 649040 provided nc=1221 (the 1224 quoted appears to be the number of tracks before formatting). I got this information partly by experiment, partly by looking at the specs in the 5000/200 appendices, so I cannot guarantee that I am right. -- John Haxby, Definitively Wrong.
