     _R_e_a_d_a_l_l reads all of the named device in large chunks.  It  reports
about  blocks that it cannot read. Unlike _d_i_s_k_c_h_e_c_k, it does not attempt
to write on the disk, making it safer to use when one is worried about a
sick  system.   When  the ---bbb flag is given, the output is a shell script
that calls the _b_a_d_b_l_o_c_k_s program to marked all the bad blocks.  Whenever
installing  MINIX,  it  is wise to run _r_e_a_d_a_l_l with the ---bbb flag first on
all the hard disks.
