Nope. FreeBSD does not support the SUN filesystem. SUN does not use a PC type 
partition table (called slices in FreeBSD terminology) on Sparc systems 
(which the Ultra 10 is). And, as Lowell mentioned, there is the endian issue.

Good the disk works.

If you want to learn a lot about filesystems, you could spend the next year 
writing a  program to access the raw disk device and start  picking apart the 
contents of the disk one block/byte at a time.
