Sorry, I can't help. However, my experience with IBM stink pads has been nothing but problems. Terry -----Original Message----- From: Janina Sajka [mailto:janina@xxxxxxx] Sent: Sunday, March 04, 2001 4:09 PM To: speakup at braille.uwo.ca; ma-linux at tux.org Subject: A Tale of Two SCSI CD ROMS And, it's a tale of woe! <grin> I am trying to figure out why one of my ide-scsi CD ROM devices works just like it should, while the second one doesn't. I suppose it could be something to do with the complexity of the hardware setup. This is an IBM Thinkpad T20 attached to an IBM docking station--at least it's attached when both devices are present together. The one CD ROM, and it's a CDRW, hence the ide-scsi, is on the Thinkpad itself in an IBM Ultrabay, as they call it. The second is in the dock, also in an ultrabay. I have no problems mounting the first, and no success at all mounting the second. In fact, when I try, I hard-hang the system so that I have to force power off--not even a ctrl-alt-del does the trick. The devices are definitely there. /proc/scsi/scsi reports: Attached devices: /Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: MATSHITA Model: UJDA310 Rev: 3.53 Type: CD-ROM ANSI SCSI revision: 02 Host: scsi0 Channel: 00 Id: 01 Lun: 00 Vendor: TEAC Model: CD-224E Rev: 2.7B Type: CD-ROM ANSI SCSI revision: 02 Host: scsi1 Channel: 00 Id: 06 Lun: 00 Vendor: CWS ORB2 Model: -SE U ID 6 Rev: D29 I have /dev/scd0 and /dev/scd1. If I try, just for grins, mounting /dev/hde (the second device), I get a very polite error message suggesting that I should be using my ide-scsi. What I don't seem to have--and this is where I begin to lose my understanding of how this all works--is sr0 and sr1. These are referred to as the system boots--but they don't seem to be anywhere around: Mar 4 15:31:59 toccata kernel: Kernel command line: BOOT_IMAGE=current ro root=301 BOOT_FILE=/boot/vmlinuz-2.4.2 hdc=ide-scsi hde=ide-scsi Mar 4 15:31:59 toccata kernel: ide_setup: hdc=ide-scsi Mar 4 15:31:59 toccata kernel: ide_setup: hde=ide-scsi ...

I can't imagine the SR0 and SR1 device designations are meaningless--but I don't see them in /dev.
