That's in order to remain compatible with messdos and other operating
systems that silently assume that fdisk partitions (FreeBSD slices)
must always be aligned to track or cylinder boundaries (however
ficticous the geometry figures might be on a modern disk).

The only way to avoid this is using a ``dangerously dedicated'' disk
where all the disk space is devoted to FreeBSD.  This will dedicate
any and all blocks of your disk to FreeBSD.

``busy'' == ``not ready''

Not sure.  You didn't tell us about your CD drive, and infact, didn't
really tell us at all what's actually going wrong there.  Neither did
you write about your FreeBSD version.

That's most likely something with the CD-ROM handling.
