NAME    [Toc]    [Back]

     diskinfo -- get information about disk device

SYNOPSIS    [Toc]    [Back]

     diskinfo [-v] [-t] disk ...

DESCRIPTION    [Toc]    [Back]

     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 information
 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.
