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 partitions, 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.

If you get READ/WRITE errors and the drive simply dies then it might be the case. Else it is a system issue. There are quirks for mass storage which you can add to sys/dev/usb/storage/umass.c . --HPS On Wednesday 18 November 2009 08:33:07 Guojun Jin wrote: > Did newfs on those partition and made things worsen -- restore completely > fails: (I had experienced another similar problem on an IDE, which works > well for 6.4 and 7.2, but 8.0.)
