.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.
|
|
