The mystery of the maniacal cd systems Something is awry with my shiney new Plextor CD-RW drive. dmesg reports the following on boot: acd0: CD-RW <PLEXTOR CD-R PX-W4012A> at ata1-master using PIO4 acd1: DVD-ROM <DVDROM 12X> at ata1-slave using PIO4 Using the magic of sysctl as described in ata(4), I've enabled DMA on both devices. This shouldn't make a difference as they both operate tolerably with DMA enabled, however I should mention it anyway. I can not mount verified good iso-9660 cdroms in the Plextor drive (acd0c). I have tried at least 6 different data cds, and not a single one will take. Every cd does take in the DVD-Rom (acd1c) though. To further confuse issues, the Plextor does indeed burn CDs quite happily with burncd. What follows is a demonstration of burncd creating a working CD using acd0c, mounting and reading it in acd1c, and then failing to mount it using acd0c. I'm puzzled. As always, any help will be met with appreciation and a large virtual fruit or vegetable of your choice. drizzle# /usr/local/bin/mkisofs -U -R -o /root/imagefile.iso /kernel.GENERIC Warning: creating filesystem that does not conform to ISO-9660.
