Comment 84 for bug 149076

If the owner/permissionms change while writing, this may be a hint
that the problem is caused by the well known non-cooperative behavior
from "hald" that interrupts the write process on Linux. Hald implements
in incorrect method for detecting a media change on Linux and in turn
tries to read from the partial written media whie the write process is not
finished.

If you like to verify this, you could use the original cdrecord and write
the cd in -raw96r mode (which makes the write process invisible for hald).

The original software is here:
