33 \fIReadall\fR reads all of the named device in large chunks.
34 It reports about blocks that it cannot read.
35 Unlike \fIdiskcheck\fR, it does not attempt to write on
36 the disk, making it safer to use when one is worried about a sick system.
37 When the \fB\-b\fR flag is given, the output is a shell script that
38 calls the \fIbadblocks\fR program to marked all the bad blocks.
41 it is wise to run \fIreadall\fR with the \fB\-b\fR flag first on all
