Problem reading CD on freebsd burnt on freebsd

Post by K Nagaraja » Sat, 15 Jun 2002 18:20:34



Hi,

At office, I have burnt an image of a file (name in 8.3 format, about
9MB size) in the standard
ISO 9660 format using the mkisofs and burncd utilities available on
freeBSD (v4.5).
When I tried to read it on my home PC, both in NT and freebsd (I have
both installed
on my home PC), I am facing 'bad address' or read error problems. What
could be the reasons ?
At office, I used a HP ReWritable CD drive. At home, I am using a
Samsung CDROM drive. I have
recorded the data at the lowest speed (-s 1), but stll it doesn't help.
Pls help!

cheers,

Nagarajan

Did you close the CD with the burncd switch/command "fixate"?
Can you read the CD on your box at the office?

 
 
 

1. Problems burning CD-R with cdwrite-1.6a12 on FreeBSD 2.2.5-R

I just purchased a Sony CDU-926S SCSI CD-R:

(ahc0:4:0): "SONY CD-R  CDU926S 1.1g" type 5 removable SCSI 2
cd1(ahc0:4:0): CD-ROM cd present [210262 x 2048 byte records]

Despite the fact that it ID's as a CD-ROM, this device is, indeed, a CD-R.
(In fact, I recorded a CD under Windows using Adaptec CD Creator, and it
worked fine!)

It is definitely listed as being a compatible unit in the cdrecord README.

In any case, I tried using it to burn an audio CD under FreeBSD.  I used
the tosha port to write out my favorite tracks from several CD's onto my
SCSI Jaz drive, and tried to burn them onto a brand new CD-R as follows:
(yes, I am running as root-- note the "#" prompt:)

- -----

- -audio /jaz/track*
Cdrecord release 1.6a12 Copyright (C) 1995-1998 J?rg Schilling
TOC Type: 0 = CD-DA
scsidev: '4,0'
scsibus: 0 target: 4 lun: 0
cdrecord: Cannot do inquiry for CD-Recorder.
cdrecord: Undefined error: 0. test unit ready: scsi sendcmd: fatal error
cmd finished after 0.000s timeout 40s
- -----

The CD-R works great otherwise -- I can mount and use CD-ROMs with it
under FreeBSD, and it burns disks perfectly under Windoze.

Does anyone have any idea of what I'm doing wrong, or why this isn't
workout for me?  Please let me know.  Thanks!
