Backpack cdrom

[kfoss]

Good Day,

I have been using a Backpack CDROM connected to the parallel port. Under MDK 9.2 I coiuld mount it under /dev/pcd0. Now under MDK 10.0 I cannot. The /dev/pcd0 device did not exist do I created it with mknod. The /dev/pcd0 directory has two subdirectories ataraid and something like cccsi.

 

Anyways, it used to work under 9.2 but not under 10 so something with devices have chaged. I insert the paride, bpck and pcd modules as per normal and everything looks fine under dmesg.

 

Any ideas what I;m doing wrong?

Try creating the device with mknod if it's not in /dev:

 

# mknod -m 666 /dev/pcd0 b 46 0

 

I got the major and minor numbers from mdk9.2.

Did anyone get the Microsolution's parallel port Backpack CD-Rewriter working under Mandrake 10? Mine is a 6 Series model and I remember having able to use it under Mandrake 9.2 also.

 

Creating a device with mknod does not help. I says the following:

 

[root@aryan .]# mount /dev/pcd0 /mnt/cdrewriter/

/dev/pcd0: Invalid argument

mount: block device /dev/pcd0 is write-protected, mounting read-only

/dev/pcd0: Invalid argument

mount: /dev/pcd0: can't read superblock

[root@aryan .]#

 

Anyone?

I think it's because in Mandrake 10, ppdev (Parallel Port module) is not loaded by default. Therefore, most parallel port devices will not function properly.

 

Try loading ppdev module first by typing this command as root

modprobe ppdev

or if you want it to be loaded everytime you boot up, edit your /etc/modprobe.conf and put this line

ppdev

 

Hope it works.

I think you mean /etc/modprobe.preload

[DragonMage]

Oops.. yeah.. it's /etc/modprobe.preload

[Guest sandeepkhanna]

After modprobing ppdev, I still cannot get it to work.

 

[root@aryan .]# mount /dev/pcd0 /mnt/cdrewriter

mount: block device /dev/pcd0 is write-protected, mounting read-only

mount: No medium found

[root@aryan .]#

 

Previously I had created a /dev/pcd0 entry which is

 

[root@aryan .]# ll /dev/pcd0

brw-rw-rw- 1 root root 46, 0 Sep 8 07:03 /dev/pcd0

[root@aryan .]#

 

What's going wrong??
