Hi, i have been trying to install my old Matsushita CW-7502 CD-R SCSI burner for a long time but i am unable to do so. I am currently running Fedora Core 1. Can anyone help? Thanks

MR

What all have you done already?

What errors are you getting when trying to mount the drive?

Can you post an error log of some CD-R software?

In addition:
Do you have any other SCSI devices and are they working correctly?
Does the SCSI controller BIOS recognize the drive correctly?

Does linux recognize the drive? i.e.
look at the output of dmesg. Any messages for the drive?
look at the output of cat /proc/scsi/scsi

Well i just installed Fedora, and realised it is not detected. I went to system tools -> Hardware Browser, then under Unknown devices i see: ABP5140:Unknown . This is the same message i get in Windows 2000. But in Windows 98 SE, it works fine.

I am trying: mount /dev/sdb /mnt/scsi and i get the error message:
mount: /dev/sdb is not a valid block device

I currently dont have any CD-R software installed on Fedora, i will do it tonight, and let you know. Thanks

MR

No i dont have any other SCSI devices, on the CD-R.
I am pretty sure the SCSI controller BIOS recognize the drive correctly as it works fine on my Windows 98 SE. Also the fact that, when i bought the computer brand new 6 years ago, the burner came with it, so the guyz should have fixed that even if there was a problem.

I dont think linux actually recognizes the drive. I had a look at the dmesg and i cant see the drive there. Everything else is there though. Would you like me to copy and paste the entire message here? Itś every long though.

Here is the output of cat /proc/scsi/scsi :

[root@local root]# cat /proc/scsi/scsi
Attached devices: none

Thanks for all you help so far, very much appreciated.

MR

BTW your device ID for the SCSI CD should be /dev/scd0.

Do you know what kind of SCSI controller you have? Is linux loading the modules. check using the command lsmod.

This is the output of lsmod:
sg 35436 0 (autoclean) (unused)
scsi_mod 110280 1 (autoclean) [sg]

This is the output of /dev/scd0:

[root@local root]# /dev/scd0
bash: /dev/scd0: Permission denied

I dont understand how can i have Permission denied? I am logged in as root.

MR

I installed X-CD-Roast and it doesnt detect my CD-R. It only detects the dvd-rom.

MR

I guess at this point, i should give up...?

MR

All I can tell from the output of lsmod and cat /proc/scsi/scsi is that the SCSI controller module is not being loaded.

What is the output of lspci? This should tell you what kind of SCSI controller is installed in your PC. It should also be displayed when the controller BIOS does it scan at boot. What does windows say for your SCSI controller device?

Since the SCSI controller module isn't being loaded at boot you will not see any messages relating to the writer.

Do you see any messages relating to the controller from the output of dmesg?

Here is the output of lspci:

>>It should also be displayed when the controller BIOS does it scan at boot. What does windows say for your SCSI controller device?

It actually doesnt show up.

From the dmesg i can see the following thing:

SCSI subsystem driver Revision: 1.00

MR

Is it a Advansys ABP5140 ISA SCSI card?

I wouldn't know if FC1 still provides the module. You might also need to load isapnp.

try
modprobe advansys

>>Is it a Advansys ABP5140 ISA SCSI card?

I just check the Unknown Devices section under Hardware Browser and yeah it says:

ABP5140: Uknown !!!!!!!!

>>try modprobe advansys

I did, and then the busy light comes on in my burner, it flickers for a while and my whole system freezes and i had to restart manually. I think i might need to load it during startup. Can anyone tell me how i can do that? I think we are on the right tract, and itś just a matter of time before we fix this problem
