SCSI Optical device
 

Hi,
I have a SCSI-2 Optical device (HP C1113F) connected to a scsi controller (Adaptec AHA-2920).
I've read the kernel documentation and build fdomain as a module.
As root user I give modprobe fdomain (qith a disc into the optical d.), the device's led blink.
So this is cat /var/log/messages

scsi2: <fdomain> No BIOS; using scsi id 7
scsi2: <fdomain> TMC-36C70 (PCI bus) chip at 0xa400 irq 11
scsi2 : Future Domain 16-bit SCSI Driver Version 5.51
Vendor: HP Model: C1113F Rev: 1.48
Type: Optical Device ANSI SCSI revision: 02
scsi.agent[1591]: how to add device type= at /devices/pci0000:00/0000:00:0c.0/host2/2:0:0:0 ??
sda: Unit Not Ready, sense:
READ CAPACITY failed.
Write Protect is off
SCSI device sda: drive cache: write back
sda:<3>Buffer I/O error on device sda, logical block 0
sda:<3>Buffer I/O error on device sda, logical block 0
Attached scsi removable disk sda at scsi2, channel 0, id 0, lun 0

Of course fidsk /dev/sda failed.
I've also tried to run vmware with sg2 connected: i see the disc, i can eject it but i can't read.

Why?


Thanks
