I've never tried with conv=noerror, but dd has worked fine for me on several occasions when extracting ISO images from data CDs and DVDs. I don't use it any more because it is slow, cp and cat give the same result and are faster. -- Neil Bothwick ERROR #0915: MONITOR NOT PRESENT.

I've read that dd actually has problems reading from cdroms and isos produced with something like dd if=/dev/cdrom of=my.iso conv=noerror would be invalid.

Not yet, but I just noticed that without -clone option image is iso compatible (at least for solaris cd1) so maybe dd conv=noerror would work. And I still wish to mount "cloned" image like with daemon-tools on windows... Is there any solution to this? (except not mounting them) -- gentoo-user@gentoo.org mailing list

But some CDs have errors (scratches) that cp/cat can't handle. Why readcd makes once iso and once "not iso" compatible image files? -- gentoo-user@gentoo.org mailing list

[gentoo-user] readcd -clone and iso9660 ?
I made a copy of 6 cdroms with readcd -clone f=iso -noerror retries=1 and only two of them I can mount -t udf,iso9660 ./iso /mnt/cdrom -o loop These two are a copy of a "protected" game CD and others are images of solaris CDs. I can mount solaris' CDs with mount -t iso9660 /dev/cdrom /mnt/cdrom but I can't mount images of them. Is there any way to bypass problem with solaris CDs or is there any tool to convert images made by readcd -clone to iso image? -- gentoo-user@gentoo.org mailing list
