NAME
diskscan - scan a disk for bad blocks
SYNOPSIS
diskscan [ -W ] dev
DESCRIPTION
diskscan performs a verification pass over a formatted dev-
ice 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 tem-
perature, humidity, and electrical supply. It is best if
the system administrator adheres to the manufacturer's
defect list and performs frequent backups.
ADDED VALUE
This entry, supplied by INTERACTIVE Systems Corporation, is
an extension of UNIX System V.
