DISKSCAN(8) Maintenance Commands and Procedures DISKSCAN(8)
NAME
diskscan - perform surface analysis
SYNOPSIS
diskscan [
-W] [
-n] [
-y]
raw_deviceDESCRIPTION
diskscan is used by the system administrator to perform surface
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 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(8), 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(8) for an
explanation of
SCSI and
IDE device naming conventions.

The
format(8) utility is available to format, label, analyze, and
repair
SCSI disks. This utility is included with the
diskscan,
addbadsec(8),
fdisk(8), and
fmthard(8) 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(8) utility.
