(Deprecated: -o rea) This subcommand runs a read test by reading a random data pattern from the tape and verifying that it matches the written data. The rtest subcommand can be used after the wtest subcommand to verify the data. An optional block size, count, and repetition can be specified with the -b, -c, and -r flags, respectively. If the block size is fixed, then the count specifies the number of blocks to read on each repetition. If the block size is zero (variable), then the count specifies the number of bytes to read on each repetition. The default is a block size of 10240, a count of 20 blocks, and a repetition of 1.
