acd0 problems during install.

[xi0nxj]

Hey, I'm about to install PCBSD but after when I am asked weather to boot PCBSD installer, start in safe mode etc. I get this message:

acd0: FAILURE - READ_BIG timed out
acd0: FAILURE - READ_BIG retrying
acd0: FAILURE - READ_BIG retrying

And so on.
I have tried booting from two CD drives on the same machine, I just burned it at 4x. I could burn another CD but I only have one blank one left so I want to try to not waste it.

The error indicates the system can't read something from the CD.

Options:
- Check md5sum of ISO is what it should be
- Check physical connections
- Clean CD Drive
- Different Media

Are your optical drives SATA?
I read in another FreeBSD forum that SATA ATAPI is unsupported. I'm having the same problem with my Optiarc SATA burner.
