.FL "\-b" "Produce shell script on \fIstdout\fR that calls \fIbadblocks\fR"
|
|
.FL "\-t" "Just print device size"
|
|
.SH EXAMPLES
|
|
.EX "readall /dev/hd0" "Read all of \fI/dev/hd0\fR"

|
.EX "readall -b /dev/hd1 >s" "Generate shell script on \fIs\fR"

.SH DESCRIPTION
|
|
.PP
|
|
\fIReadall\fR reads all of the named device in large chunks.
|
|
It reports about blocks that it cannot read.
|
|
Unlike \fIdiskcheck\fR, it does not attempt to write on
|
|
the disk, making it safer to use when one is worried about a sick system.
|
|
When the \fB\-b\fR flag is given, the output is a shell script that
|
|
calls the \fIbadblocks\fR program to marked all the bad blocks.
|
|
Whenever installing
|
|
\s-1MINIX 3\s-1,
|
|
it is wise to run \fIreadall\fR with the \fB\-b\fR flag first on all
|
|
the hard disks.
|
|
