<p style="margin-bottom: 0in;">I'm having a problem mounting my new
CDRW DVD in my new machine I just built. The motherboard is an Intel
DP35DP, and I connected the CDRW DVD via ribbon cable into the
motherboard IDE slot. Centos 5.1 is installed and functioning fine
so far (other than this problem).</p>
<p style="margin-bottom: 0in;"><br>
</p>
<p style="margin-bottom: 0in;">I can't mount the CDRW-DVD unit. I was
able to run cdrecord with the command:</p>
<p style="margin-bottom: 0in;">cdrecord -v speed=2 dev=6,0,0 -data
/home/mydir/Desktop/backup_bootimage.iso to copy a file that I
downloaded, apparently the data copy went fine, but when I ejected
the CD and then tried to re mount the same CD to read the file, it would not
mount. So then I tried mounting the Centos 5.1 distro disk that I used to install the OS, and am having the same problem with the distro disk. If anyone could give me some suggestions or insights I'd
appreciate it. I have provided some data below.</p>
<p style="margin-bottom: 0in;"><br>
</p>
<p style="margin-bottom: 0in;">I tried the below commands after
ejecting the CD and then executing the commands while the drawer is
open, and I got the below outputs:</p>
<p style="margin-bottom: 0in;"><br>
</p>
<p style="margin-bottom: 0in;"># sudo mount -t iso9660 /dev/sr0
