Hi there. I just got a new CD-RW drive and am trying to get it working
under Linux. I've got the ide-scsi modules all loaded, but have weird
errors when trying to mount a disk.
Here are the messages from "dmesg" that I get when the ide-cd and
ide-scsi modules are loaded. My DVD-ROM is /dev/hdc, and the CD-RW is
/dev/hdd (or /dev/sr0):
-----------------------------------------------------
hdc: ATAPI DVD-ROM drive, 512kB Cache, UDMA(33)
Uniform CD-ROM driver Revision: 3.12
ide-cd: ignoring drive hdd
scsi0 : SCSI host adapter emulation for IDE ATAPI devices
Vendor: SONY Model: CD-RW CRX160E Rev: 1.0e
Type: CD-ROM ANSI SCSI revision: 02
Detected scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0
sr0: scsi3-mmc drive: 32x/32x writer cd/rw xa/form2 cdda tray
-----------------------------------------------------
So, it looks like the drive is attached to /dev/sr0 properly. Then, I
run "cdrecord -scanbus" to make sure:
-----------------------------------------------------
Cdrecord 1.9 (i686-pc-linux-gnu) Copyright (C) 1995-2000 Jörg Schilling

scsibus0:

-----------------------------------------------------
So, it REALLY looks like it's working. However, here's what I get when
I try to mount an ordinary data CD:
-----------------------------------------------------
athens:~# mount -t iso9660 /dev/sr0 /cdrw
mount: block device /dev/sr0 is write-protected, mounting read-only
SCSI cdrom error : host 0 channel 0 id 0 lun 0 return code = 28000000
[valid=0] Info fld=0x0, Current sd0b:00: sense key Hardware Error
Additional sense indicates Logical unit communication CRC error (Ultra-DMA/32)
I/O error: dev 0b:00, sector 64
isofs_read_super: bread failed, dev=0b:00, iso_blknum=16, block=32
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
or too many mounted file systems
-----------------------------------------------------
I've tried this with both kernel 2.4.1 and 2.4.3 and have the exact same
error. I've also tried multiple data CDs and have the same messages.
The CD-RW is a Sony CRX-160E, plugged in to an Asus A7V motherboard (the
PCI bus is described by "lspci" as "VIA Technologies, Inc. VT8363/8365
[KT133/KM133 AGP]"). I'm not sure what other information I can provide,
but I'll be happy to give anything else that might be needed to help fix
this problem.
Thanks a lot!
Tim
