RE: [SLE] CD recording difficulties
AFAIK it is possible to use the ATAPI tape driver connected to hdd, but you must tell the system to keep its hands of the CD writer with the following line in your modules.conf: options ide-cd ignore=hdc Now the IDE initialisation ignores hdc completely, and you should be able to use your tape driver on hdd. Again, AFAIK :-) Regards Harry

I have resolved the problem described below. It was a hardware fault, but a very subtle one. I summarise the solution here so that others do not fall into the same trap.
The CD writer is an ATAPI unit connected as hdc. But CD writers need a scsi interface, so the system is set to run ide-scsi emulation. On booting, the ide-scsi module is loaded (lilo conf entry ' append = "hdc=ide-scsi" '). On the same ide interface there was an ATAPI tape drive connected as hdd.
I had previous used the writer with success under SuSE 7.3, and I suddenly
realised that at the time the tape drive was installed in another computer.
When I shut down the computer, disconnected the tape drive and rebooted, the CD writer worked perfectly.
MORAL: do not mix scsi and ide on the same bus.
As a result I must increse the number of IDE channels onmy computer. Can anyone recommend a PCI card that provides one or two more IDE channels ( hde, hdf and possibly hdg and hdh)?
TIA

Thank you for the tip - it wasn't quite right; the line should be options ide-scsi ignore hdc Regards Basil
