When a new medium is inserted, hald-probe-volume is launched at some time with a 10s timeout.
This value seems to be too short for some hardware.
Indeed a DVD-R inserted in LG GSA-H30N recorder is never really recognized because hald-probe-volume is killed after the timeout.
Increasing this value from 10s to 15s solves the bug (in hald/util.h), the DVD-R
is correctly recognized.
The problem has been found on Ubuntu 7.10 with hal 0.5.9.1, udev 113, kernel 2.6.22.

Seems that Yann and I figured this out independently. I sent explanations and the (trivial) patch to the upstream ML recently:
