To copy stuff, you read from the source and write to the destination. Which of these operations do you think should require write permission on the source? I guess you have never copied anything from a CD?

DAR_CP(1)						      General Commands Manual							 DAR_CP(1)

NAME
dar_cp - disk archive copy SYNOPSIS
dar_cp <source file> <destination file> dar_cp -h dar_cp -V DESCRIPTION
dar_cp is similar to the standard 'cp' command, except it does not stop copying when an I/O error is met. Instead, it skips a bit further and continues to copy the rest of the file, as much as possible. dar_cp only accepts full filename (not directory) as argument. The reason of its existence in dar package is that you need it if you use Parchive with dar and have a corruption on a CD-R or any other read-only medium. You need to copy the corrupted slice on a read-write filesystem, for Parchive be able to repair it using slice associated redundancy files. OPTIONS
-h Displays help usage. -V Displays version information. EXIT CODES
dar_cp exists with the following codes: 0 upon normal execution (be some corrupted parted skipped or not) 1 syntax error on command-line 2 could not open source or destination files 3 any other system error met during the copy 5 when some data could not be copied due to I/O error SIGNALS
Any signal sent to dar_cp will abort the program immediately, there is no way to have a proper termination before the end of the process SEE ALSO
dar(1), dar_xform(1), dar_manager(1), dar_slave(1) KNOWN BUGS
None actually. AUTHOR
