DISKSCAN(1M)							  DISKSCAN(1M)

NAME
       diskscan - perform surface analysis

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

DESCRIPTION
       diskscan	 is used by the system administrator to perform surface analy‐
       sis on a portion of a hard disk. The disk portion may be a  raw	parti‐
       tion  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  standard 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.

ATTRIBUTES
       See attributes(5) for descriptions of the following attributes:

       ┌───────────────┬─────────────────┐

SEE ALSO

       attributes(5)

NOTES
       The  format(1M)	utility	 is  available	to format, label, analyze, and
       repair SCSI disks. This utility is included with the diskscan,  addbad‐
       sec(1M), fdisk(1M), and fmthard(1M) commands available for x86. To for‐
       mat an IDE disk, use the	 DOS format utility; however, to  label,  ana‐
       lyze,  or  repair  IDE disks on x86 systems, use the Solaris format(1M)
       utility.
