mount_cd9660 is supposed to, out-of-hand, mount the last data track
on a CD, Worked for me as such on older, other boxes.
Well, I had tried that earlier on my box, but let me perform that
in front of an audience:
# dmesg | grep acd0
acd0: DVD-ROM <SAMSUNG DVD-ROM SD-608> at ata1-master using WDMA2
# sysctl -a | grep hw.ata
hw.ata.ata_dma: 1
hw.ata.wc: 1
hw.ata.tags: 0
hw.ata.atapi_dma: 1
hw.atamodes: dma,dma,dma,---,
# cdcontrol -f /dev/acd0c Info | grep data
11 54:12.68 7:08.38 243818 31988 data
# mount_cd9660 -s 243818 /dev/acd0c /mnt
mount_cd9660: /dev/acd0c: Invalid argument
I've tried this with both DMA and PIO on my drive, which I'll point
out is a DVD-ROM drive, not a CD-ROM drive.
With your pointers, though, I was able to correctly use 'mount'
using both of my test CDs on another box running 4.1-RELEASE with
a classic CD-ROM drive:
acd0: CDROM <FX4010M> at ata0-slave using UDMA33
So, this issue at hand is some combination of my kernel (4.5-RELEASE)
and my hardware (DVD-ROM). Any further suggestions?
