Multisession CDs with 'burncd'

[Alejandro Pulver]

Hello,

How can I burn multisession CDs with 'burncd'?

I have FreeBSD 5.3.

# atacontrol list

ATA channel 0:
    Master:  ad0 <ST340014A/3.16> ATA/ATAPI revision 6
    Slave:  acd0 <HL-DT-ST GCE-8523B/1.01> ATA/ATAPI revision 0
ATA channel 1:
    Master:  ad2 <Maxtor 6E040L0/NAR61590> ATA/ATAPI revision 7
    Slave:       no device present

I tried this:

== first session ==

% mkisofs -o proj.iso -allow-lowercase -allow-multidot Projects

# burncd -e -f /dev/acd0 -m -s 4 -v data proj.iso fixate

(works, I can mount it, read it, read it with Windows, and it appears
to close the session but not the disk)

== second session ==

# burncd -f /dev/acd0 msinfo
0,12794

% mkisofs -o test.iso -allow-lowercase -allow-multidot -C 0,12794
instalar

# burncd -e -f /dev/acd0 -m -s 4 -v data test.iso fixate

adding type 0x08 file test.iso size 40492 KB 20246 blocks 
next writeable LBA 12794
addr = 12794 size = 41463808 blocks = 20246
writing from file test.iso size 40492 KB

only wrote -1 of 32768 bytes: Input/output error

fixating CD, please wait..

(it does not write anything)

------------------------------------------------------------------

What am I doing wrong?

What is the DAO mode?

Should I try with SCSI programs like 'cdrecord', etc.? Are them better?

Thanks and Best Regards,
Ale
