can't create multisession CD

[Alexandr]

Hello.

I have writeble CD and want to create multisession disk.
I create first session.
root# mkisofs -o /tmp/test.iso -J -R ~/part1/*
root# burncd -mf /dev/acd0 data /tmp/test.iso fixate

this is OK.

but second step:


root# mkisofs -o tmp.iso -R -J -M /dev/acd0 -C `burncd msinfo` xpdf.tbz
root# burncd -tmf /dev/acd0 data tmp.iso fixate
next writeable LBA 14234
writing from file tmp.iso size 1644 KB

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


Why???
I find examples on google.com/bsd and all of them is same...

(for some CD)
root# cdcontrol info
Starting track = 1, ending track = 1, TOC size = 18 bytes
track     start  duration   block  length   type
-------------------------------------------------
    1   0:02.00   0:37.59       0    2834   data
  170   0:39.59         -    2834       -      -
