Mounting CDs on IDE CDRW Drives

From Anthony Dearson on Thu, 23 Sep 1999

You had a question about mounting CDRW drives when using SCSI emulation. I found that using /dev/scdX allowed mounting the CDRW. /dev/cdrom can be linked to that instead of /dev/HDX Tony Dearson

Ironically I guessed that and gained some first hand experience about a week ago when I bought and installed one of the silly things into my workstation. I also found out about the need to append hdc=ide-scsi on my shiny new 2.0.38 kernel to get the SCSI emulation working. I also found out that my normal CD-ROM drive (/dev/hdb) can't read CDRW media (though it seems to do O.K. with the CDR's that I burn in the same drive).

Thanks for confirming my guess.

More CDRW

From David G. Watson on Thu, 23 Sep 1999

I have an IDE CD-RW drive, and it's just a little bit tricky getting it to work. The guy who you responded to in TAG is very close - he's just looking at the wrong device. The one he really wants is /dev/scd0. I haven't managed to get all CD playing software to recognize this when I'm not root, but most X CD players can (xplaycd, workman, synaesthesia, kscd, etc.).

Hope this helps, -Dave Watson

Yep! I got one and had to learn a bit about it myself.

Even more on CDRW

James, Regarding,

"Reading CD Discs on an IDE CDR Drive From balou nguyen on Wed, 14 Jul 1999 "

He needs to use: mount -t iso9660 /dev/scd0 /mnt/cdrom

if his CD-ROM drive is the master on the secondary IDE controller.

I just had this same problem on my system. It seems that after enabling SCSI emulation, the CD-ROM drives are seen as SCSI devices.

So, the slave drive on the secondary IDE controller is /dev/scd1.

You have probably already found this out but I couldn't resist trying to help the "Answer Guy" for a change.

Thanks for a great column!

Another fan, Lance DeVooght

Obviously the CDRW medium as arrived! I've gotten more clarifications on that point then I can remember getting on any other.
