Name

readom

Synopsis

readom dev=device [options]

Read or write compact discs. The device is usually specified as dev=scsibus/target/lun or dev=target/lun if the device is on the default SCSI bus. The default SCSI bus is bus 0, the target is the ID number, and the lun is the logical unit number.

Options

-c2scan

Do a C2 error scan. If any C2 errors are found, specifying the speed= option to reduce the speed may help.

-clone

Read all data and the table of contents, and put the table-of-contents data into a file with the same filename as specified with f= but with a .toc extension.

-d, debug=num

Increment the debugging level by 1 with -d or set the level to num with debug. Specifying -dd is the equivalent of debug=2.

dev=target

Set the SCSI target.

f=filename

Specify the file from which input should be read, or to which output should be written. If the filename is given as -, use standard input or standard output, respectively.

-factor

Print the speed factor for the meshpoints= option, based on the current medium’s single speed. Works only if readom can determine the current medium type.

-fulltoc

Read the full table of contents from the current CD and display it in hexadecimal.

kd=num, kdebug=num

Modify the kernel debugging level while SCSI commands are running, to do kernel debugging.

meshpoints=num

Print the read speed at num locations, and produce a list of values suitable for plotting. The output is written to standard output.

-nocorr

Ignore read errors, doing no error correction. Switches the drive into ...
