Re: bad CRC in rar file

One of the rar files has a bad CRC so rar fails to extract the ISO image. Does anyone know if there is a different application that can extract this image even though there are crc errors? I looked at the rar manpage and it didn't seem like rar could do it. The unrar utility in ports says the kb command line switch will keep broken. Remember mounting a bad ISO image may crash your computer. Generally one uses par files to validate and repair rar files before reassembling the original image. To generate par files for this purpose one has to start with a good set of rar files. -- David Kelly N4HHE, [EMAIL PROTECTED] Whom computers would destroy, they must first drive mad. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

What is the purpose of par files if you already have a good set of rar files? Is the idea that the same person that distributes the original rar files will also distribute par files with them? Yes. Par as in parity. The par files would contain redundant information which is intended to be used to verify/repair broken file(s) (not necessarily rar files). Essentially the same as Forward Error Correction. If you have incomplete or damaged files then you need par files to repair. Can not create par files out of bad files. -- David Kelly N4HHE, [EMAIL PROTECTED] Whom computers would destroy, they must first drive mad. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
