.SH NAME
diskscan \- perform surface analysis
.SH SYNOPSIS

.SH DESCRIPTION
.sp
.LP
\fBdiskscan\fR 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 \fBaddbadsec\fR(1M), which will remap them.
.SH OPTIONS

The following options are supported:
.sp
.ne 2

.sp
.ne 2
.mk
.na
\fB\fB-W\fR\fR
.ad
.RS 6n
.rt  
Causes \fBdiskscan\fR to perform write and read surface analysis. This type of surface analysis is destructive and should be invoked with caution.

\fB\fB-y\fR\fR
.ad
.RS 6n
.rt  
Causes  \fBdiskscan\fR to suppress the warning regarding destruction of existing data that is issued when  \fB-W\fR is used.

.SH NOTES
.sp
.LP
The \fBformat\fR(1M) utility is available to format, label, analyze, and repair \fBSCSI\fR disks. This utility is included with the \fBdiskscan\fR, \fBaddbadsec\fR(1M), \fBfdisk\fR(1M), and \fBfmthard\fR(1M) commands available for x86. To format an \fBIDE\fR disk, use the \fB DOS\fR \fBformat\fR utility; however, to label, analyze, or repair \fBIDE\fR disks on x86 systems, use the Solaris \fBformat\fR(1M) utility.
