For example, when a disk has been formatted 51(by 52.Xr format 8 ) , 53you can check that 54hard errors has been taken care of by running 55.Nm "" . 56No hard errors should be found, but in many cases 57quite a few soft 58.Tn ECC 59errors will be reported. 60.Pp 61While 62.Nm 63is running, the cylinder number is printed on 64the console for every 10th cylinder read. 65.Sh EXAMPLES 66A sample run of 67.Nm 68is shown below. 69In this example (using a 750), 70.Nm 71is loaded from the root file system; 72usually it 73will be loaded from the machine's 74console storage device. Boldface means user input. 75As usual, ``#'' and ``@'' may be used to edit input. 76.Pp 77.Bd -unfilled -offset indent -compact 78.Li \&\*[Gt]\*[Gt]\*[Gt] Ns Sy B/3 79.Li \&%% 80.Li \&loading hk(0,0)boot 81.Li \&Boot 82.Li \&: Sy \&hk(0,0)drtest 83.Li Test program for stand-alone up and hp driver 84.Pp 85.Li Debugging level (1=bse, 2=ecc, 3=bse+ecc)? 86.Li Enter disk name [type(adapter,unit),\ e.g.\ hp(1,3)]?

Note, however, that 99the device number 100in the diagnostic messages is identified as 101.Em typeX 102instead of 103.Em type(a,u) 104where 105.Ar X 106\&= a*8+u, e.g., hp(1,3) becomes hp11. 107.Sh SEE ALSO 108.Xr bad144 8 , 109.Xr format 8 110.Sh HISTORY 111The 112.Nm 113command appeared in 114.Bx 4.2 . 115.Sh AUTHORS 116.An Helge Skrivervik 117
