diskscan(1M)

NAME

     diskscan - perform surface analysis

SYNOPSIS

     diskscan [-W] [-n] [-y] raw_device

DESCRIPTION

     diskscan is used by the system administrator to perform sur-
     face  analysis on a portion of a hard disk. The disk portion
     may be a raw partition or slice; it is identified using  its
     raw  device  name.  By default, the specified portion of the
     disk is read (non-destructive) and errors reported on  stan-
     dard  error.  In  addition,  a progress report is printed on
     standard out. The list of bad blocks should be  saved  in  a
     file  and  later  fed  into  addbadsec(1M), which will remap
     them.

OPTIONS

     The following options are supported:

     -n    Causes  diskscan to suppress linefeeds  when  printing
           progress information on standard out.

     -W    Causes diskscan to  perform  write  and  read  surface
           analysis. This type of surface analysis is destructive
           and should be invoked with caution.

     -y    Causes  diskscan to  suppress  the  warning  regarding
           destruction  of  existing data that is issued when  -W
           is used.

OPERANDS

     The following operands are supported:

     raw_device
           The address of the disk drive (see FILES).

FILES

     The  raw  device  should  be  /dev/rdsk/c?[t?]d?[ps]?.   See
     disks(1M)  for  an explanation of SCSI and IDE device naming
     conventions.

NOTES

     The  format(1M)  utility  is  available  to  format,  label,
     analyze,  and  repair  SCSI  disks. This utility is included
     with the diskscan, addbadsec(1M), fdisk(1M), and fmthard(1M)
     commands  available  for x86. To format an IDE disk, use the
     DOS format utility; however, to label,  analyze,  or  repair
     IDE  disks  on x86 systems, use the Solaris format(1M) util-
     ity.
