# @(#)disktab 8.1 (Berkeley) 6/9/93
#
# Disk geometry and partition layout tables.
# Key:
# dt controller type
# ty type of disk (fixed, removeable, simulated)
# d[0-4] drive-type-dependent parameters
# ns #sectors/track
# nt #tracks/cylinder
# nc #cylinders/disk
# sc #sectors/cylinder, nc*nt default
# su #sectors/unit, sc*nc default
# se sector size, DEV_BSIZE default
# rm rpm, 3600 default
# sf supports bad144-style bad sector forwarding
# sk sector skew per track, default 0
# cs sector skew per cylinder, default 0
# hs headswitch time, default 0
# ts one-cylinder seek time, default 0
# il sector interleave (n:1), 1 default
# bs boot block size, default BBSIZE
# sb superblock size, default SBSIZE
# o[a-h] partition offsets in sectors
# p[a-h] partition sizes in sectors
# b[a-h] partition block sizes in bytes
# f[a-h] partition fragment sizes in bytes
# t[a-h] partition types (filesystem, swap, etc)
# b[0-1] primary and secondary bootstraps, optional
#
# All partition sizes contain space for bad sector tables unless
# the device drivers fail to support this. Smaller disks may
# not have all partitions and all disks have no defaults for
# the `h' partition. The strategy here is that `a' always
# has the same amount for all disks. The `b' partition is
# four times `a' while `c' is always the entire disk. The
# sum of `d', `e', and `f' is equal to `g' which is everything else.

# NOTE: The RZ58 uses a recording technique called zoned recording.
# Using this technique, the number of sectors per track will vary
# depending on what zone of the disk is in use (simply multiplying
# ns*nt*nc does not give true capacity of the drive). The ns (number
# of sectors per track) is calculated by "ns = total sectors/(nt*nc)"
# and is a rounded value. Therefore, the value "ns" is an approximation,
# not a true representation, of what is stored on disk.
#
# The 'c' partition listed below gives the true size of the RZ58
# (this information can be obtained by use of the DEVGETGEOM ioctl).
