FreeBSD 5.x and burncd-ing raw files.

I used to be able (on 4.x) to burn any old file to a CDROM
like this:

   $ burncd -f /dev/acd0 -s 12 data /tmp/plain.text fixate

and read it back like this:

   $ dd if=/dev/acd0 of=/tmp/temp bs=2k

But under 5.2.x, I get this output:

   dd: /dev/acd0: Input/output error
   0+0 records in
   0+0 records out
   0 bytes transferred in 0.000700 secs (0 bytes/sec)

Has the design changed or does that look like a bug?

(BTW, I've tried several other block sizes.)

Second question: What is "/dev/acd0t01"?

Thanks.
