DISKINFO(8)

NAME

     diskinfo -- get information about disk device

SYNOPSIS

     diskinfo [-tv] disk ...

DESCRIPTION

     The diskinfo utility prints out information about a disk device, and
     optionally runs a naive performance test on the device.

     If given no arguments, the output will be a single line per specified
     device with the following fields: device name, sectorsize, media size in
     bytes, media size in sectors, firmware cylinders, firmware heads, and
     firmware sectors.	The last three fields are only present if the informa-
     tion is available.

     If given the -v option, the fields will be printed one per line with a
     descriptive comment.

     The -t option triggers a simple and rather naive benchmark of the disks
     seek and transfer performance.
