Folks,

I'm new at this bsd OS, but did get an xinuos open server 10 operating
which is BSD. I've managed to get everything working with some trial and
error picking the correct ports for necessary libraries.  The BSD os is
stable version 11.3.

The problem popped up when I tried to make a backup tape using a usb dat160
internal drive.  After testing a lot I found that the drive would read
tar and dd formats correctly.  It did only a flawed read on cpio tapes.  It
always failed on any write with CAM errors and scsi errors.  Research on
the web proved that this is not an uncommon problem with usb storage 
devices.  I am not interested in being a freeBSD test bed!  I need a stable
OS for my customers.

My first question - would updateing to stable 12.1 solve this?  If so what
are the updateing pit falls?  Would switching to a dat160 scsi lvd drive
solve the problem?

Thanks all,
Wayne Anschutz
