+.Os
+.Sh NAME
+.Nm diskinfo
+.Nd get information about disk device
+.Sh SYNOPSIS
+.Nm
+.Op Fl ctv
+.Ar disk ...
+.Sh DESCRIPTION
+The
+.Nm
+utility prints out information about a disk device,
+and optionally runs a naive performance test on the device.
+.Pp
+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 information is available.
+.Pp
+If given the
+.Fl v
+option, the fields will be printed one per line with a descriptive comment.
+.Pp
+The
+.Fl c
+option triggers a simple measurement of the I/O read command overhead.
+.Pp
+The
+.Fl t
+option triggers a simple and rather naive benchmark of the disks seek
+and transfer performance.
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Fx 5.1 .
+.Sh AUTHORS
+.An Poul-Henning Kamp
+.Sh BUGS
+There are in order of increasing severity: lies,
+damn lies, statistics, and computer benchmarks.
