Re: mkisofs error
Be _very_ careful, genisoimage is full of bugs and creates defective filesystems. Do not use it, genisoimage is unmaintained and does not even support files 4 GB! Other well known bugs in genisoimage create defective directory entries for . and ... This is because genisoimage is based on a 5 year old version of mkisofs with additional bugs added that never have been in the original software. Mkisofs has no known bugs and is well maintained. I see no reason why mkisofs should be the cause for your problem... Well you did not describe the problem in a way that could allow to analyse the background. Possible reasons for your problem could be read errors on the medium, check using: readcd f=/dev/null whether the medium is fully readable. Another possible reason could be a problem in the filesystem driver of the kernel. If a file gives a read error, there should be a kernel message related to the problem. If you are able to extract the file using isoinfo using the ISO-9660 name of the file (be careful not to use the defective isoinfo that comes with cdrkit), the problem is definitely not in mkisofs. BTW: do you use a recent or an outdated mkisofs? The latest version of mkisofs is 2.01.01a66 and FreeBSD by default unfortunately distributes extremely outdated versions.

mkisofs error
My data backups to DVD use mkisofs to build ISO9660 DVDs like so: mkisofs -J -joliet-long -r -hide-rr-moved -graft-points dir1 dir2 dir3 and then piped into cdrecord. However, I found a problem with one file that casts some doubt on the whole process. The file is named img_0185-6x4crop.jpg and is 3,309,906 bytes. On the hard drive, it reads fine. The filename is present on the DVD, but the file always gives a read error: # file img_0185-6x4crop.jpg img_0185-6x4crop.jpg: ERROR: cannot read `img_0185-6x4crop.jpg' (Input/output error) It's not a one-time error; every DVD always has the same problem. What is going wrong? A poison filename? -Warren Block * Rapid City, South Dakota USA ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
