Gentoo2 root # dd if=/dev/cdrom of=EXILE_DISK_1.iso dd: reading `/dev/cdrom':Input/oupuut error 3304+0 records in 3304+0 records out It fails for some of these reasons: 1. broken CD 2. end of CD (to check it, mount cd, run df and compare sizes) 3. copy protected CD. It can be a problem to differentiate reasons 1.and 3. because some manufacturers probably use the same copy protection method as used on floppies in old times ... some theory follows: Sector on CD is 2352 Bytes, 2048 for data, the rest is for headers and CRC. Normally every sector's CRC is calculated from sector's data (IMHO calculated by CD burner itself). In this way it's possible to read a CD even if reading of some bits fails (for different reasons). Sector intentionally burned with broken CRC and/or header (yes, it's possible to do!) can be used as copy indicator, because on original CD read error occurs (data still can be read OK), but on copied CD the error is corrected. dd command will fail with broken sector msg or so. U can still read it using this command: dd if=/dev/cdrom of=my.iso conv=noerror bs=1k count=[size shown by df] The problem is to burn the image now, because if u burn it in usual way, CRC/header of the broken sector will be burned properly. There are for sure other possibilities how CD's can be copy protected and still readable by dd without any error ( e.g. info from CD's header can be checked etc.) I don't know about linux SW, which can clone such CD's, but I heard clonecd or nero for micro$hit should do it. noro -- [EMAIL PROTECTED] mailing list

That's really interesting. Can you explain 'mounting on loopback'? What is that? I only have one Linux book (Linux in a Nutshell) and it doesn't have loopback in the index. It allows you to mount a file system from a file (it loops accesses to this nested file system back into VFS, hence the name). As already pointed out, you need kernel support and the -o loop option to mount. For example, you can mount an ISO image resting on a hard disk-based FS to one directory, and then mount a ROMFS image off the mounted ISO FS to another directory. I actually tried this, it really works! You just have to unmount in the reverse order of mounting these nested file systems (otherwise umount will simply tell you that the file system is still in use). -- [EMAIL PROTECTED] mailing list

Apparently CloneCD is not being developed much any more, and the Alcohol 120% site is very active, so I gave it a try. After burning 2 coasters while learnnin to use the program (and making it much more difficult than it had to be!) I got a good copy in about 10 minutes of using the program correctly. One very useful site is here http://www.makeabackup.com/modules.php?name=Game_Protections_List which give a good list of exactly what protection specific games are using. Armed with this info you then know how to run Alcohol 120% using its default settings and things jsut work. It should be noted that not all cd-r's can reproduce this data. Very true I found out. Luckily all of mine have the capability to burn subchannel data correctly, or appear to. Again, thanks very much.

Re: [gentoo-user] Possibly copy protected CDs?
Shoot, I don't have it installed here, but there is an ebuild for it, and once installed, copying a CD was really easy. Basically, you use cdrdao to create an image of the cd (a set of bin/cue files), then use it again to write them to a blank CD. I got it from just looking at man cdrdao and trying it, and did not make a single coaster. This may sound like RTFM, but google can probably provide you with better instructions than I can. :-) Larry [EMAIL PROTECTED] 02/03/04 3:54 PM Larry Meadors wrote: You might try cdrdao, I have used it to copy all kinds of stuff.
