NAME

diskscan − perform surface analysis

SYNOPSIS

diskscan [ −W ] [ −n ] [ −y ] raw_device

DESCRIPTION

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(1M), which will remap them. 

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

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

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

FILES

The raw device should be /dev/rdsk/c?t?d?[ps]?.
