HELP!

What could cause disklabel -r to correctly see the disk geometry, but when
I try to boot to the same disk, or mount that disk from another FreeBSD
disk, I get all kinds of messages like:

sd1: raw partition size != slice size
sd1: start 0, end 49999, size 50000
sd1c: start 0, end 430835, size 4308352
sd1: truncating raw partition
sd1: rejecting partition in BSD label: it isn't entirely in the slice
sd1: start 0, end 49999, size 50000
sd1a: start 0, end 65535, size 65536

etc. for my remaining partitions sd1b (swap), sd1c (entire disk), etc.
FreeBSD occupies the entire disk.

What's strange in the above message is the second line: there is no
partition definded by disklabel of size 50000. So for some reason the
kernel copy of the disklabel is not matching the disk copy of the
disklabel. How could this be?? Please tell me how to correct this error
*without* losing the information on that disk! I have backups of the
critical data, but rebuilding the entire disk will be a logistical
nightmare! This problem has come on suddenly, where I've been
booting/mounting this disk for several weeks now.

Please email if you post. Thank you thank you thank you if you can help.
I'm deparate!
