I just installed an HP Surestore CD writer in my FreeBSD-2.1R box. I have a couple of questions: 1. It is probed like a regular scsi CD rom, i.e. : (ncr0:6:0): "HP C4324/C4325 1.20" type 5 removable SCSI 2 cd1(ncr0:6:0): CD-ROM cd present.[330928 x 2340 byte records] Is this correct?? Will I be able to issue scsi commands to the cd1 device? (i.e. shouldn't I be using the worm device to write CD's) 2. I can mount a cdrom, and it seems to work fine, but it is slower than my 2x toshiba cdrom drive. I thought this thing was supposed to read at 4x speed. 3. When I initially tried to mount a cdrom, I got a bunch of scsi error messages. Then, it seemed to mount fine the second time I tried it. After I moved it to scsi ID 6, it was fine. Maybe it didn't like something when the other devices were accessed right after it was during the probe? Maybe it is a priority thing? Any ideas?? Here's the log: Jan 24 11:55:24 jjarray /kernel: ncr0:4: ERROR (80:140) (8-2a-0) (0/13) @ (544:900b0000).

I suspect I will be doing alot of tests with the laser off (: Any suggestions would be greatly appreciated. Fred.
