NAME

diskscan − scan a disk for bad blocks

SYNOPSIS

diskscan [ −W ] dev

DESCRIPTION

diskscan performs a verification pass over a formatted device specified by dev.  The −W option specifies a more robust and destructive scan. 

DIAGNOSTICS

The program maintains a simple display of progress on stdout. Detected bad sector numbers are written, new-line character separated, to stderr.

BUGS

diskscan performs only the simplest of scans, even when −W is specified.  It is likely to find only the grossest of disk errors.  A truly thorough scan could take days, and still might not find defects that appear at extremes of temperature, humidity, and electrical supply.  It is best if the system administrator adheres to the manufacturer’s defect list and performs frequent backups.
