Problem detect/mount dvd drive force to switch back to WinXP

I just installed the Knoppix into my laptop. However, when I try to click the CD-ROM icon, the following error occured

Unable to run the command specified, The file or folder

file:/mnt/cdrom does not exist


I will be appreciate if there's anyone who can help me resolve this problem. Hope to receive the response as soon as possible. Thanks.

I really appreciate if there's anyone who can help me resolve this problem. Without the drive, it would be useless since sometimes I need to load the stuffs from the drives.

you might try to delete the icon and rightclick on the desktop, create new device-->whatever-->choose the approriate device.
you might have to symlink /dev/dvd to your actuall dvd but...
now it "should" work.
if not.
i first run the comand

Code:

---

dmesg|grep dvd; dmesg|grep DVD

---

then from output i get the actuall devic-file.
mine looks like this.

Code:

---

dmesg|grep dvd; dmesg|grep DVD
sr0: scsi3-mmc drive: 32x/32x writer dvd-ram cd/rw xa/form2 cdda tray
hdc: DVD-ROM DDU1621, ATAPI CD/DVD-ROM drive
hdc: ATAPI 40X DVD-ROM drive, 512kB Cache, UDMA(33)

this means my /dev/dvd should be a symlink to /dev/hdc

Code:

---

ln -s /dev/hdc /dev/dvd

Thank you so much for the help. However, when I try to run the command in the root. There's an error
"ln : '/dev/dvd': File exists

I will be appreciate if you can help me again once more. Again I am very new to Linux, and henceforth don't know all the details like command to use yet. Thanks again.

Try to force with ln -sf /dev/scd# /dev/dvd. This way by passes any other symlinks and sets it directly to the drive. All you need is the appropriate scd#. This you can find in the output from what the last post said. This must be done as root. scd# will be the scsi#, as in scsi2 --> scd2. Hope this helps.
