    Playing a CD With Hdd Install

    I've got a poor man's install, and when I try to play a cd, I can't, because file:/cdrom is the hard drive. Is there some way to unmount the hard drive from the cdrom drive? How do I paly cd's with a poor man's install?

    Don't get too hung up in the title that shows up in your home directory. From reading your other post , it sounds as if you are running just fine with the fromhd boot option, but you're concerned about the fact that the title says file:/cdrom. Can you eject the CD while running your poor man's? If so, then it shouldn't be tied up. Poor man's involves running from a hd image of the cd rom drive. IOW, there may be some aspects of Knoppix which "believe" that it's running from CD, even when it isn't. You said that you had your installed apps in the home directory. If you are really running from CD, Knoppix won't let you eject the disk.

    Maybe I'm misunderstanding - sorry if I seem dense, but the only thing I saw in your other post about the hd being tied up was that it appeared that it wasn't mounted as read/write. Check out my reply .

    Yeah. That helps me understand it, but it doesn't help me play a cd or game (not to be rude)

    Well, so, can you eject the CD while running Knoppix or not?

    Yes. I can. But if I put in a cd, and try to play it, it doesn't recognize it. It says file:/mnt/cdrom doesn't exist or something similar to that.

    In knoppix, the cdrom is mounted at /cdrom by default (not /mnt/cdrom). So if you want to mount the cd, it should be:-

    mount /cdrom

    Are you trying to play music cd? If yes, you may have to set the permission of /dev/cdrom to 777. I think the more correct method is to add the user to the audio group + others but I simply chmod 777 /dev/cdrom.

    For music cd, vcd and dvd, there is no need to mount if you are using grip, kscd, xine, gmplayer......

    Well I tried playing it in Xine and other players, but it just said file:/mnt/cdrom doesn't exist. And when I click home window-->devices-->CD-ROM it says the same thing. It also might be of some help to know that my hda1 partition is under home window-->devices-->hda1 (cdrom). Do I have to unmount the hard drive from the cdrom? Is it trying to open the wrong thing by opening file:/mnt/cdrom instead of file:/cdrom? Did I do my PMI wrong? Everything else (besides my Winmodem, but I have many threads made dealing with that) works fine.

    First of all, I really don't think that the hard drive, or how it's mounted, is at issue. What about your cdrom icon on your desktop - does it have a little green triangle in the corner of the icon to indicate that it's mounted? Do you have more than one? Have you tried clicking the cd-rom icon? If a window opens when you do, it should be mounted, and you should be able to redirect Xine to the location shown in the address.

    I don't know what's on your CD, but if it has an executable, you should be able to click and run from the window.

    No, it's not mounted, and mount /cdrom tells me that hda1 is already mounted on cdrom, and umount /dev/hda1 says /cdrom is busy. Question=How do I unmount the hda1 from the cdrom? And then where should it go?

    I'm honestly not trying to frustrate you or get in your way. But I think that one of the reasons your questions isn't being answered as you ask it is that the way you ask it does not make sense. To my knowledge, there is nothing in knoppix that will "mount hd to cdrom". If you are determined to unmount any device, you can do it by right-clicking the icon and selecting "unmount", or alternatively, issuing the "umount" command (note the spelling with one "n") from the console. If it's a permission issue, you can execute a command as root by preceding it with "sudo" (e.g., "sudo umount /dev/cdrom"), you can set a root password by typing "sudo passwd" to allow root commands on the desktop, or you can type "su" in the console to make your whole console session as root, if that's what you really want to do. I'm betting that there's not one person in this entire forum who has any experience "unmounting a hd from the cdrom", so if no one is answering your question, that's probably why.

    If you are going to issue the mount command from console, take a moment to learn the proper syntax, either by typing "man mount" or looking here . You mount an object to a mountpoint. So, to mount the cdrom, figure out the name of the device in question - is it cdrom, or scd0, hdc, or something else entirely? Assuming that it's "cdrom", the normal syntax to mount it (ignoring optional items) is "sudo mount /dev/cdrom /mnt/cdrom" (only root can mount in console). Personally, I would just click the desktop icon (making sure that I was clicking the right one, of course).

    Sorry I can't be more precise in addressing your problem, but I'm flying blind. Not only can I not see your system, but I'm in Windows right now. What storage icons do you have on your desktop? Which ones will not mount with a left click?
