Hi folks, I just wanted to copy a data CD. So I thought I'd first read it out. After I had put the CD into my ATAPI CD-ROM drive, I issued the following command: dd if=/dev/acd0a of=cdimage But it didn't work. I received a message saying "acd0a - Invalid Argument". Next, I tried something different, namely: cat /dev/acd0a | dd of=cdimage and that did work! Any clues why my first attempt (only using dd and not cat) failed?
