Hello.
I have trouble with a PlexWriter PXR412C, Firmware Rev 1.07. This writer
is adapted to a Adaptec 2940UW SCSI Controller, Firmware Rev 2.57.2, SCSI ID 6.
When booting the system, BIOS recognizes the writer, FreeBSD recognizes it, too.
This is the output of dmesg:
--- snip
cd1 at ahc0 bus 0 target 6 lun 0
cd1: <PLEXTOR CD-R PX-R412C 1.07> Removable CD-ROM SCSI-2 device
cd1: 10.000MB/s transfers (10.000MHz, offset 8)
cd1: cd present [4294967146 x 2048 byte records]
--- snip
Seems to me to be absolutely normal.
The Adaptec BIOS is configured to try wide negotiation (turned it off, but no result), all
options are YES on that target ID except multiple LUN. I fiddled around with some options
without success.
When trying cdrecord -scanbus (V1.8) produces the following error:
Cdrecord 1.8 (i386-unknown-freebsd4.0) Copyright (C) 1995-2000 Jörg Schilling

When trying to burn a CD ROM, I get this error:
root: /cdr/image: cdrecord speed=4 dev=6,0 4.1-install.iso

scsidev: '6,0'
scsibus: 0 target: 6 lun: 0
cdrecord: No such file or directory. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root.
I tried to compile cdrecord V 1.9, but I can not compile it althoug I have the latest
Mk files installed and the apropriate stuff installed for cdrecord 1.9. Compilation
target directory is always empty, after the compiler runs for a minute ...
Please help, thanks in advance,
Gruss O. Hartmann
