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.)
