From d43e5e5b5a2e27fb75a6e19cca457ca40ad160e4 Mon Sep 17 00:00:00 2001 From: Jan Drzewiecki Date: Tue, 26 Oct 2010 12:10:57 -0400 Subject: [PATCH] cdrom_id: Fix media state for unreadable DVDs If the disc is unreadable and reading of the first 32 blocks fails set the cd_media status to 0 (not present). This will prevent udev from executing blkid next that tries to determine fs on the disc and which in this case may seem to hang forever locking the drive.
