NAME

disk/prep − make disk partition table

SYNOPSIS

­disk/prep [ ­-r ] ­special

DESCRIPTION

A partition table is stored on a disk to specify the division of the physical disk into a set of logical units.  On Plan 9 the partition table is a list of triples: name, starting sector, and ending sector.  The first two partitions must have the names ­disk and partition; the ­disk partition records the starting and ending sectors for the whole disk, and the ­partition partition, typically the last sector on the disk, holds the partition table itself. 

­Special is the maximal prefix of names of the logical units on the disk, for example #w/hd0.  ­Prep reads and prints the associated partition table and then enters a simple interactive mode to control editing the table. 

The single option ­-r (readonly) prohibits writing the table on disk.
