In regard to the message below referencing the OVERview units and seagate
harddrives, there needs to be some clarification. Although we have had
problems with the seagate harddrives shipped with the OVERview units it has
been dealt with on a case-by-case basis. Emperical data tells us that when
the unit operates properly over an extended period the harddrive remains
intact. i.e. the harddrive units suffer from infant mortality. It has been
found out that the newer harrdrives that we are now shipping do not suffer
from this problem. At NIH we are going to replace 2 of the OVERview units
and see how they perform. If this proves to solve the problems we will then
replace the remaining units.

I am not subscribed to p4200 but this mail was forwarded to me by
RAF@CU.NIH.GOV. We at NIH currently have 7 OVERVIEW stations.  All of
our stations have crashed/hung at one time or another with similar
symptoms.  Proteon customer service is telling us that there is a
problem with the seagate hard drives originally supplied with these
units.  They say that they are now using conner hard drives instead
for newly made units.  They say that they will replace all of our
units with the new drives, however, they say that it may be 3 weeks
until we get our first replacement.  I will post to this list the
results of our experiences with the replacement units if and when
that happens.
