.TH DISKPART 8 "18 July 1983"
diskpart \- calculate default disk partition sizes
is used to calculate the disk partition sizes based on the
default rules used at Berkeley. If the
option is supplied, tables suitable for inclusion in a device driver
option is supplied, an entry suitable for inclusion in the disk
Space is always left in the last partition on the disk
for a bad sector forwarding table. The space reserved
is one track for the replicated copies of the table and
sufficient tracks to hold a pool of 126 sectors to which bad sectors
are mapped. For more information, see
The disk partition sizes are based on the total amount of
space on the disk as give in the table below (all values
are supplied in units of 512 byte sectors). The `c' partition
is, by convention, used to access the entire physical disk, including
the space reserved for the bad sector forwarding table.
In normal operation, either the `g' partition is used, or the
`d', `e', and `f' partitions are used. The `g' and `f' partitions
are variable sized, occupying whatever space remains after allocation
of the fixed sized partitions.
If the disk is smaller than 20 Megabytes, then
aborts with the message ``disk too small, calculate by hand''.

If an unknown disk type is specified,
will prompt for the required disk geometry information.
Certain default partition sizes are based on historical artifacts
(e.g. RP06), and may result in unsatisfactory layouts.
When using the \-d flag, alternate disk names are not included
Does not understand how to handle drives attached to a UDA50.
