Cannot mount CDs or DVDs

[Lexx]

I'm having a problem mounting both CDs and DVDs. I just installed FreeBSD 7.1 on an HP Pavilion DV9825nr laptop.

When I attempt to mount a known-good CD or DVD using the command
mount /dev/acd0 /cdrom (following the FreeBSD handbook and all other commands in it)
and I get the following error:
mount: /dev/acd0 Invalid sectorsize 2352 for superblock size 8192: Invalid argument

$ dmesg | grep acd0 shows:
acd0: DVDR <TSSTcorp CDDVDW TS-L632N/0503> at ata0-master PIO4
my /etc/fstab
/dev/acd0 /dvdr cd9660 ro,noauto 0 0
When I run "cdcontrol -f /dev/acd0 info
Starting track = 1, ending track = 1, TOC size = 18 bytes
track start duration block length type
-------------------------------------------------
1 0:02.32 60:14.05 32 271055 audio
170 60:16.37 - 271087 - -

which is correct.

Can anyone help with this? Thanks in advance.

Are you trying to mount an audio cd?

I'm trying to mount anything. Data cd, music cd. I've tried CDs and DVDs. I still get the same thing. The drive worked with Windows before I reformatted.

I did fail to mention that my laptop is a 64bit Dual core, but I'm using the x86 version for the NVIDIA accelerated video driver. Not sure if that causes a problem.

OK, but you can't mount audio cd.
Try for example with the FreeBSD cd/dvd.
