It looks like a system issue since it also happens to the SATA drive.
The USB drive seems having more difficulty. I will back up rest
Then redo the slice and partition to see if problem goes away.
If so, then 8.0-R has a backward compatibility issue on the partition
table or format to older FreeBSD release.

I'm not sure if this is an USB issue or not. If you get READ/WRITE
the drive simply dies then it might be the case. Else it is a system
There are quirks for mass storage which you can add to
