   We currently have two Hitachi 512-17, 170Mb drives.  We plan to replace
our system disk with a Hitachi DK514-38, 380Mb drive.  If this works, we
will probably replace our other disk too.  I have received email from
Jim Diamond indicating that we should be able to replace our data drive
with out any problems, however we weren't sure about the system disk.
This is why we ordered only one drive, if the drive doesn't work as a
system disk, then we will use it as a data disk.  However, if it does
work as a system disk, then we will probably get the second drive.
   Not too long ago I found out that there seems to be a problem with
using two 380Mb drives.  SGI said that the current hardware and 3.6 OS
will support two 380Mb drives.  I talk to someone that actually tried
to do this, and the system keep crashing.  It turned out that there was
a bug some ROM's.  I don't know when or if the correction got into any
other machines or not.  We plan to cross that bridge when we get to it.
