Newbie install error mounting /dev/acd0 on /dist

[Adam King]

Hi all.

I am new to FreeBSD and recently bought a packaged CD set and am
installing it on a second hard drive. I am booting directly from the CD,
configure all relevant option and and when I commit to installing, it
fails with the error message:

Error mounting /dev/acd0 on /dist: Input/Output error (5)

I browsed the mailing list and found another person with the same
problem, but without an appropriate fix. Does anyone know what the
problem is?

Thanks,
Adam
