Comment 47 for bug 66254

Glad to hear it works. Can you let us know what your CD drive is. There is a list of CDs for which the fix is reported good in the last 4 messages on https://bugs.launchpad.net/ubuntu/+source/hal/+bug/109763.

I patched 0.5.9 because, before working on the patch, I got the most recent HAL in case others had fixed the problem. The patch works just fine for both cases, so you might just have to use the latest sources and re-apply to avoid the irritating update messages until a patch is adopted by Canonical.

Perhaps you (and others subscribing to either 66254 or 109763 (the same problem, just expressed slightly differently)) contact the HAL developers directly with your observations (and I'm CC'ing the Debian maintainer on this).

The problem has only recently started to appear because until around a year ago (specifically N-C-B 2.14.3, last
date in the sources of which is 31/07/06) contained code that probed the disc directly when HAL failed to return the MMC value.

Debian Testing uses
2.18.2, from 29/05/07, so developers/distributors have not actually had very long to
discover that there are quite a number of folk out there with old CD
drives that used to work and that will no longer do so.

My patch to HAL was just a slight re-coding of the code from N-C-B 2.14.3, and I did that rather than simply patching N-C-B because it seemed a cleaner place to make the mod: e.g. the 'Hardware Information' Browser now reports the empty CD size, and that would not have worked unless the change were made in HAL.

Regards

David
