Copying directories from removable media?

Hi, I have a CD that has an important exam directory that i want to copy to my Linux Mint box. I subsequently ran this command:

sudo dd if=/media/LPIC\ I\ EC\ 2/ of=linux-exam bs=1 count=100

and receive this error message:

dd: reading `/media/LPIC I EC 2/': Is a directory

0+0 records in

0+0 records out

0 bytes (0 B) copied, 0.000590019 s, 0.0 kB/s

Thanks in advance..9

    I am really not sure if I understand correctly, but if you copy some cd-rom or usb flash or st. you have to use propriate file in the /dev directory eg. /dev/cdrom or /dev/sda. But I used it only for few times. Also I am not sure, if there is possible to make a copy of directory using this way, because there can be stored other directories everywhere in some device so i think that dd can be used only for coppying files eg. of devices.

    So it could look somethink like:
    dd if=/dev/cdrom of=/home/user/Desktop/MyCD.iso

    I am not sure, but I think that you can erase part of your disk by using command like that, because I destroyed my system this way. I am using flash disc /dev/sdb until this time for this case.

    dd works with file content and a directory has no content at all, that's why you are getting the error.

    As 012345JOsh says, you should point your "if" to the file that represents your removable media.
